This value represents the number of beads that have more than a single targeted clone and as a result, cannot be used for sequencing and alignment. Based on manufacturer recommendations, a sequencing run with polyclonality values of less than 40% is considered of a good quality. This value refers to the formation of a sequencing adaptor-dimer, with no targeted insert or a very short insert. The ideal distribution of fragments in the custom Ampliseq assay used in this study was aimed to be shifted towards the 150-200bp region (Figure 35). This value represents the greatest position in the read at which the accuracy in the bases meets the accuracy threshold (see an example in Figure 36). The Ion Torrent data analysis process includes several continuous steps and is summarised in Figure 37. Ion Reporter software provided the opportunity to annotate and export all the variants, including the reference calls, which was not possible with the build-in Variant Caller in the Ion Torrent Suite software. A stepwise linear regression analysis with cofactors such as sex and ancestry were implemented to find potential associations of specific phenotypic traits with genetic markers. Prediction analysis of phenotypic traits and ancestry Numerous craniofacial and pigmentation phenotypic traits and ancestry were predicted using stepwise logistic regression models. Multiple determination coefficients 2 (R) of these models were used to estimate the predictive power of the model. Prior to performing genotyping all relevant methods and use of equipment were optimised, when needed. This was necessary for the subsequent association and prediction studies, which were the main aims of this project. Introduction the sample collection process occurred over a period of three and a half years. The use of the online schedule helped with the logistics of the sample collection process. In addition, 39 individuals were sourced from the existing database, collected between 2000 to 2009. The volunteers were of various ancestries, with the majority (70%) being Caucasian. A sample set comprised of different ancestries can potentially introduce a bias in statistical analysis, due to the difference in allele distribution in various populations. However, this issue was addressed by performing a statistical correction to address the population stratification issue in the association analysis (as detailed in Chapter 5). However, collecting and genotyping of larger sample numbers is not always feasible, since it is more time-consuming and costly. Furthermore, very large sample sets often involve collaborative efforts of several researchers, which is also not always possible. An effective sample size is defined as the minimum number of samples that achieves adequate statistical power. A statistical power of 80% is considered sufficient for large scale association studies [345, 346]. In order to correct the false positive errors (type I error), either the Bonferroni or the false discovery rate correction is generally applied [347]. Given that the more often used (and more stringent) Bonferroni correction involves dividing the p-value significance threshold by the number of markers tested, a large number of samples is generally needed to compensate for this correction. In fact, results of the association analysis demonstrated that the sample size used was statistically effective (Chapter 5). However, as in most association studies, an additional set of samples might be required in order to replicate these results. There is no sample number limitation per extraction, although usually up to 24 samples are processed for easier handling. There is no specific sample number limitation per extraction, although usually up to 24 samples are processed for easier handling. Two different sets of duplicates were used due to the limited number of buccal swabs collected per person (n=4), while each two (2) were used for a single extraction. The Isohelix method resulted in the highest yield, although there was greater variability between the samples (Table 6). A candidate gene approach was chosen as the most appropriate and feasible method for this project (as discussed in Chapter 1). This approach provided information on genes and respective polymorphisms, potentially influencing craniofacial morphology (discussed in details in Chapters 1 and 2). This section provides a summary of the candidate genes and markers selection process and details of their annotation analysis. Methods Two main complementary strategies were used to generate a list of candidate markers. The first focused on searching the literature for candidate genes, involved either in normal craniofacial variation or in craniofacial malformations in both humans and model organisms. The web resources used for searching candidate genes and markers are listed in Section 2. Results and Discussion Both searching methodological approaches were performed simultaneously and pinpointed 1,088 candidate genes and intergenic regions. However, 592 of these genes showed no clear link with craniofacial development and were therefore not included. Most of these 592 genes were originally selected based on high Fst values of respective markers. This process resulted in 496 genes and intergenic regions potentially involved in regulating normal craniofacial morphology. Subsequent analysis of these 269 genes/regions using various resources for functional annotation, resulted in 137 candidate genes/regions, possessing 10,746 markers. Although Life Technologies does not provide details for the technical issues with primer design failure, the most reasonable explanation is that these markers are located in highly polymorphic or repetitive regions of the genome. These genomic regions are known to be more unfavourable for the primer design process. Given that each amplicon covers between 125 bp to 225 bp, each 108 | P a g e amplicon could potentially cover more than one polymorphism. The final hotspot file of all the markers included approximately 6,500 known markers in 985 genes/regions and was used as a reference hotspot file for variant caller in the Ion Torrent Suite and Ion Reporter software. However, it should be noted that more than 50% of these markers are not common (less than 2% frequency) and as a result were filtered from the association analysis (Chapter 5). This tool helps annotate non coding genomic regions, which typically lack genetic annotation. The analysis revealed that almost 99% of the total number of genomic regions (which may cover multiple markers) are associated with one or two genes (Figure 40), with approximately 62% of genomic regions located between 0-500 kb downstream of a transcription start site (Figure 41). Analysis of potential mouse phenotype associations confirmed that orthologous candidate markers were previously detected in mice models displaying abnormal morphology of the skeleton, head, viscerocranium and facial area, as well as specific malformations of the eye, ear, jaw, palate, limbs, digits and tail. The majority of amplicons covered multiple markers and were associated with more than one gene. An illustration of genomic location of candidate markers in respect to the transcription start site. The results of these experiments were published or submitted for publication and provided as Sections 3. The results of both studies were included in the thesis of Dr Sheree Hughes-Stumm, submitted to the Bond University [350]. The association and prediction study provided an important opportunity for evaluation of both the genotyping and statistical analysis methods and established an initial foundation for subsequent study of externally visible traits and ancestry with more advanced genotyping technology (Chapter 5). This aspect made possible performing a validation study between two genotyping methods, as detailed in Section 3. A blind test of each model using 100 samples showed the following accuracies for each of the traits investigated: 92% 96% for ancestry, 73% 94% for hair colours, 78% 97% for skin colours and 83% 87% for eye colours. At the same time, it is relatively novel and is not yet a routine method (as discussed in section 1. However, given that custom primers were designed in two multiplex pools, this required using double the amount of sequencing consumables, significantly increasing the cost and processing time. A half reaction volume is mentioned as an option in the protocol, although not officially supported by the manufacturer [340]. The manufacturer recommends using between 10pM and 20pM input, while even a slight difference. It should be noted that due to the high cost of the sequencing consumables, only a limited number of biological duplicates were assessed in this study. Materials and Methods the following items in this section (items a to d) correspond to the aims listed in the Introduction section 3. The samples with half reaction volume were merged after the first amplification step, as per manufacturer recommendations (Chapter 2. Specific Ion Xpress barcode X (X= the number of the specific barcode) adapters (Life Technologies) were ligated onto the 5 and 3 ends of each fragment and linked by nick translation (as per manufacturer recommendations) to allow for sequencing multiple samples simultaneously (Chapter 2. Library quantities were determined using the Ion Library Quantitation 139 | P a g e kit (Life Technologies). The sequencing output was assessed using the overall chip output (aligned reads), mean sequencing depths and number of targeted markers per samples. A validation of the full versus half amplification reaction volume showed that sample outputs of the half reactions performed as well as the full volume reactions (Table 7). The overall chip output is a function of various parameters, although the chip loading is the most important. These conclusions were supported by the output of subsequent chips (n=35) that were processed. Mean Sample >=Q20 read Read Variants Barcode # name Bases bases Reads length Depth detected 10-001 full IonXpress 001 volume 103,192,101 87,793,917 716,854 143 bp 322. The number of polymorphisms detected in the samples at 10pM were slightly higher than in the same samples at 20pM (5% difference). Polyclonality was the most significantly affected parameter of the run (16% at the 10pM versus 27. Generally, the higher the concentration of enriched beads, the higher the polyclonality was, which may affect the sequencing output. Following these results, the 10pM library concentration was found optimal for all the subsequent samples. The mean sequencing depth was lower when a higher number of samples per chip was used (n=32), albeit sufficient for comprehensive coverage of targeted markers. Alteration to the original chip loading protocol were assessed as recommended on the Ion Torrent community forum ioncommunity. Based on the results of this study, up to 32 barcoded samples were processed on each 316 chip. The overall discrepancy among samples analysed at low stringency variant detection settings, varied between 2 to 19 markers per sample pair corresponding to 0. In general, samples sequenced at a higher depth showed less discrepancy (three to four markers per sample pair or approximately 0. However, the percentage of inconsistent calls might not be an accurate representation, since the total number of markers can be counted in various ways, such as the total number of genotyped markers or successfully genotyped markers only. Example of three samples duplicates, sequenced on the same chip and analysed under low stringency algorithm. The discrepancy in allele calls and its percentage from the total number of calls is shown. Three duplicates (see Table 10) sequenced at significantly higher depth, showed less discrepancy between each other, compared to the same samples, sequenced at approximately ten fold less depth. In addition, the same duplicates while analysed according to the high stringency parameters, showed significantly higher concordance (from zero to only three markers difference) per duplicate (Table 12). On the other hand, applying the higher stringency settings, resulted in less markers detected (down by approximately 30%). The same samples as in Table 10, analysed using Variant Caller, according to high stringency parameters. However, prior to statistical analysis (Chapter 4) the data were filtered by a minimum coverage of x10 and genotype quality of 10 (per marker), thus reducing the potential error rate. Remarkably, an application of the high stringency analysis parameters resulted in less than 0. Therefore, for any forensic use, a high coverage (x100 or higher) followed by high stringency variant analysis parameters should be considered. For example, the Ion Torrent hardware, software, reagents and laboratory manuals in this project were updated through series of optimization as follows: the OneTouch instrument (an essential component for template preparation) was physically replaced five times in one year and its software was therefore also updated five times. A limited validation performed in this study tested the concordance and genotyping accuracy within the same platform. Given the relatively novel nature of the Ion Torrent platform, it was decided to perform a limited comparison between at least two independent genotyping methods.

Do you have any relevant literature references or reports regarding Pacific oysters that would be of value within the current study. The distribution and abundance of the non-native Pacific oyster, Crassostrea gigas, in west Devon a result of climate change. We do not hold long-term temperature records, but these should be available from the British Oceanographic Data Centre. We also hold some habitat/species information available for European marine sites that is derived through specific reporting processes. Are there any other staff contacts within your organisation that should be contacted to obtain feedback regarding this Project. There are other relevant staff but for the time being it will be easier if you contact either Rob Blyth Skyrme or myself and then we can co-ordinate Natural England responses. Established is the term used to consider species for Schedule 9 of the Wildlife and Countryside Act (as amended) 1981. So, we would consider that Pacific oysters are now naturalised or established in the wild. Natural England considers Pacific Oyster to be a non-native, invasive species in English waters. Broadly interpreted this includes threats to the entire ecosystem including human interests. The recent cases in the Wadden Sea and Denmark demonstrate how invasive Pacific oysters can be, leading to the loss of mud and sand flats as well as competing with local indigenous fauna such as native mussels. No/few natural predators so once established will potentially out-compete and dominate marine habitats C. Will colonise bare mud as well as rock habitats, potentially forming a reef monoculture which transforms estuarine and marine environments. This has the potential to effect bird feeding areas which could have a significant effect on our estuaries, of which a large proportion are protected for the nationally and internationally important bird populations that they support. They also have the potential to effect fish nursery areas, through the smothering of muddy and sandy areas which provide an essential food source. There is a real risk that once established that it will not be possible to control them, or extremely invasive methods such as dredging will be required. All the above will have the effect of permanently damaging internationally and nationally important conservation sites meaning that they will always be in unfavourable condition and will not meet good ecological status under the Water Framework Directive. Access to the coastal/estuarine environment will also be impacted as Pacific Oysters have razor sharp edges which make walking on them extremely hazardous, has been demonstrated in Sylt, Germany, Wadden Sea, Holland and Denmark. Does your organisation have any evidence of wild settlement of Pacific oysters in areas for which you have responsibility. Couzens reported the wild settlement of Pacific Oysters in areas around Plymouth, even though the Plym and Tamar estuaries do not contain any commercial Pacific oyster farms. It also showed the reef which has now formed in the River Yealm, and reported the sporadic spatfall of Pacific oysters near areas of cultivation in the Exe, Yealm and Dart estuaries, but this was in 1994 prior to the warm summers and mild winters experienced over the last 10years. This information is essentially contained within the answer to the question above on wild settlement. However, we currently have not reported Pacific oysters causing adverse effects within designated conservation sites within England. However this may in part be due to the timetable for assessing site condition being on a 6 yearly cycle, which means that the areas like the Yealm may not have been condition assessed since the development of the Pacific oyster reef. Where the invasion of Pacifics has been rapid and widespread, with areas which used to be sandflats and mussel beds now being dominated by Pacific oysters. This was reported to have lead to the reduction in eider and other birds that used to feed on the sandflats and mussel beds. However, although the focus is likely to be on protected sites, the issues are likely to be generic to inshore waters around England. What marine conservation legislation protects natural habitats & native flora and fauna from non native species and in what capacity. The review of non-native species policy by Defra (2003), provides a useful summary of the relevant legislation, the following is taken from this document: 1. This Convention requires contracting parties (of which there are 184), as far as possible and as appropriate, to prevent the introduction of, to control or eradicate, those alien. Further to this Article, the Committee of Ministers to Member States issued Recommendation R(84)14 (adopted on 21st June 1984), stating that the introduction of non-native species into the environment should be prohibited. Exceptions to this prohibition may be authorised on the condition that the potential consequences of such introductions are assessed beforehand. In Great Britain, this is transposed into domestic legislation by Section 14 of the Wildlife and Countryside Act 1981. For more information, please refer to the Habitats Regulations Guidance notes, available online: enintranet/default pages/default 37796. How is and could the Pacific oyster farm industry be affected by such legislation. Existing farm sites may also be covered under the provisions of the Habitats Regulations. Significant effects may occur even if the plan or project is some distance away [from the protected site]. The effects may be direct or indirect, temporary or permanent, beneficial or harmful to the site, or a combination of these. Applications for new farms or modifications to existing activities: Our answers to the following questions relate to new applications or modifications to existing licences that are not within Regulating or Several Orders. In the last 5 years how many applications have you been asked to comment on for new proposed Pacific oyster farms or modifications to existing operations. From the responses we have received back from our regional officers it appears that we have commented on 6 applications in the past 5 years. However this may not be a complete figure as we have not been able to get responses from all the relevant people within the short timescale of this part of the project. Those applications we have received are from a wide geographical area of the English coast. In general terms what were your recommendations in this respect and what was the eventual outcome of the applications. In general terms our recommendations have been: limits on the size and locations of operations, the use of triploid stock, the need to go through an appropriate assessment under Regulation 48 of the Habitats Regulations and the need to monitor the effects of the activities. Without reference to specific individuals what is the current status of applications that you have been asked to comment on. The current situation is that 2 of the applications have gone ahead, 1 was given permission but abandoned due to the infrastructure washing away, 1 is still in discussions with the competent authority over the impacts, 1 has gone ahead against our advice and the other is considering the possibility of undertaking an appropriate assessment. Naturalisation and wild settlement: Could the Pacific oyster now be considered naturalised. The few species we consider naturalized include species such as the rabbit, the garden snail etc which have been present for hundreds of years, not cultivated for 30 years and only settling in the wild over the last 10. Zebra mussels Dreiseina polymorpha which is invasive in North America has been present in Britain for over a century and has only recently started to cause problems here). In Europe it has taken a couple of hot summers which seems to have triggered the Pacific oyster into taking on invasive properties especially in France and the Wadden Sea. At present in Britain there is only one example of a wild settlement of Crassostrea gigas forming a reef as such, in the Yealm estuary in Devon despite quite extensive settlements. Anecdotal reports by recreational anglers suggest it is becoming an amenity issue at Southend on Sea in the Thames estuary, who have reported cutting their feet on the shore on wild settlements of C. On the continent, the status of the Pacific oyster, Crassostrea gigas, has changed from non-native to invasive. This has been brought about by recent warm summers which have resulted in an explosion of the species in some warmer areas including the Wadden Sea. It has also been found to be settling in the wild further north into Scandinavia 2 (it recently settled in Sweden at densities of up to 300/m). The nuisance value comes from it forming dense reefs and aggregations that can comprise a very large proportion of the biomass. It can replace mussel reefs and while the associated fauna is less affected, it nonetheless changes the existing habitat. In Britain, this species is a non-native and has been settling in the wild for over 10 years. As with records from elsewhere in Europe, it was initially found as individual shells attached to hard substrates. The cause of the spread lies in the cultivation of Pacific oysters on aquaculture lays. Initially its settlement in the wild in south coast estuaries was blamed on larvae being transported in gyres from France, however, their wider appearance soon showed that local recruitment was occurring. There are a range of habitats which could be colonized and changed by the settlement of Pacific oysters. Our greatest concern lies within site of nature conservation importance, however, any establishment in the wild would degrade its naturalness. There has been sparse but widespread settlement in the Menai Straits since the 1990s.

This would obviously require investment in new equipment and infrastructure which must then be recouped through sales of the product erectile dysfunction clinic generic viagra with fluoxetine 100/60 mg visa. There may also be a need to reduce stocking densities during on-growing which may mean that bigger sites are required in order to maintain the same levels of production and that additional equipment will be required impotence divorce order viagra with fluoxetine 100/60 mg with mastercard. However in order to make these sorts of additional investments growers will have to be confident that they will obtain some sort of increased return on their investment erectile dysfunction after testosterone treatment buy viagra with fluoxetine 100/60mg without a prescription. This has brought the first sale price down to 15p per shell (11 to 13p if sold unpurified) although prices of 20 to 25p per shell are still being achieved by some growers selling to niche markets (Syvret and Utting erectile dysfunction doctors huntsville al cheap viagra with fluoxetine 100/60 mg mastercard, 2004) psychological erectile dysfunction drugs purchase viagra with fluoxetine without a prescription. It is recommended therefore that support be given to industry to help develop a quality grading system that could then be circulated to buyers of Pacific oysters erectile dysfunction johannesburg viagra with fluoxetine 100/60 mg low cost. Through such a system of product quality promotion it may be possible for growers to obtain a better price for their product in comparison to poorer quality products. Cooperative approach An example of an industry cooperative approach to initiating a quality scheme can be seen in the Tasmanian Pacific oyster industry. Up until 15 years ago the industry in Tasmania was developing with little control or policing of standards. As a result outbreaks of sickness in consumers were common leading to poor consumer confidence which together with haphazard grading and poor quality products allowed the buyers to constantly push down prices. This company set a standard price for shareholder-growers based on a quality scheme (see Figure 36) with payment within 7 days of delivery once the customer had confirmed that they were happy with the quality of the consignment. The company was responsible for finding the sales and the grower harvested to order. This approach meant a radical change in farming practices for many growers, especially with respect to stocking densities, more care in husbandry, selection, grading, packing and transport to market. Oysters are now sold on a region of origin basis, an approach similar to segmentation in the wine industry. Label Rouge certification in this case covers various features including meat quality and the natural greening process which is found in certain oyster ponds in Marennes. An indication of the premium generated by this label can be seen from a simple price comparison seen recently. There has also recently been the development of a quality scheme for Pacific oysters in Ireland following an initiative between Bord Iascaigh Mhara, industry and a certification company. A new marketing initiative promoting a saleable oyster product is desperately needed to help increase home consumption. Local agricultural shows and seafood festivals are becoming increasingly popular for promoting sales (selling product, distributing leaflets etc. Almost half of questionnaire respondents in this region had undertaken some element of triploid production with one farm relying solely on triploid seed for their commercial production. South East growers have in the past used triploids and some continue to rely on this type of seed. However the availability of wild Pacific oyster seed through natural settlement has meant that many growers no longer rely on hatcheries for their sources of seed. Growers in the East of England did not seem to have tried triploid production and they commented that their oyster growth rates were already good in that region. The Southern England respondent to the questionnaire had used triploids in the past but already experienced high growth rates on their sub-tidal site. In North Wales the two oyster growers contacted were about to commence trials with triploid Pacific oysters that were being funded by the Countryside Council for Wales in a joint initiative to investigate mitigation measures to prevent the possibility of wild settlement of oysters in the Menai Straits. In Northern Ireland only one grower reported having had any experience of growing triploid oysters and this was only as a small proportion of their production in order to maintain supply to customers when diploids were in advanced spawning condition i. Interestingly concerns about mortality levels following grading in summer months and unmanageable growth rates for triploids were mentioned by most Northern Irish growers even though most had no experience of growing this type of oyster. It seems therefore that viewpoints amongst growers with no experience of using this type of seed are being strongly influenced by the minority of growers that have tried triploids. Whether a fair assessment of the advantages and disadvantages of using this type of seed is being put forward is questionable. However the evidence to back up these reports seems in some cases limited and so it is recommended that more detailed follow up of these reports of mortality issues should be undertaken to see if this is an inherent issue with the use of triploid seed or whether it is in fact related more to the need to alter husbandry or management practises when dealing with this different form of oyster. Because of this they were trialling triploid half-ware oysters for the first time in 2008. Where oysters are overstocked the crowding effect produces misshapen oysters and the competition for food leads to oysters growing through the mesh in an effort to reach food. One answer to this problem would be to reduce the stocking densities of oysters held in oyster bags. However this would of course lead to a requirement for a larger growing area to accommodate the same level of production, more oyster bags and more steel trestles. The latter is particularly important as current high commodity costs have pushed up the cost of steel considerably. The economic impact of such a change in practises would need to be assessed taking into consideration both the additional costs and potential savings in labour that might arise through a reduced need for handling and grading oysters. The fast growth rates result in the need for regular handling, turning and grading. However as mentioned above a reduction in stocking densities in oyster bags should help to overcome this problem. Another possibility to help combat this problem might be a change in the culture equipment used. The main advantages of this are that there is improved hydrodynamics allowing more water movement and therefore food through the growing volume as well as a reduced need and time spent turning the cylinders in order to ensure the oysters do not grow into each other and maintain a good conformation (Legg, 1998). Any change in culture systems would of course require expenditure on new rearing cylinders as well as the infrastructure to hold or mount them. Such purchases of new equipment would have economic consequences and impacts that would require further investigation. By way of a crude comparison one French hatchery who supply mated or natural triploids quoted a price of 7 (5. Wright acknowledged that triploids offered a good alternative to diploid oysters at times of the year when diploids would either be in poor condition post-spawning or considered too milky. However when opening at a table in a restaurant it was not considered acceptable to have an average of 3-4 oysters per dozen in poor condition for this niche high value market i. This was not however during the course of this study highlighted as a problem by growers using triploids for supply to the bulk market although this problem may arise if variability is too high. These are then transferred to bottom lays, usually producing one of the better meat yields in Ireland. This change in culture sites has proved effective but necessitated an application for a new licence. At a second site the triploids also show very fast growth but no licence could be obtained to move the culture area and so poor shell shape has been experienced at times. This grower continues to grow a proportion of triploids in order to be able to supply the French market when their oysters are milky. With respect to hatchery practises Thompson reports that seed transferred in warmer months from the hatchery to farms can suffer high mortalities, but producing seed in the winter is impossible thus leaving a very narrow window for producing seed. Some farmers will only therefore buy larger part-grown triploids in order to reduce the risk of mortalities. This is of course more costly for the grower but as a consequence places the burden of risk with respect to mortalities on the hatchery producer. The positive aspects reported are good flavour with bigger meats without being milky. In these poorer growing conditions diploids are often said to still grow reasonably. There are also reports that triploids can grow too fast for some farms to manage leading to issues with poor shell shape. Mortalities have been experienced where triploid oysters are handled during the warmer months. In order to try and clarify some of these points Christopher Le Masurier of the Jersey Oyster Company (Jersey, Channel Islands) was also interviewed to obtain an overview of their experiences of producing commercial quantities of both triploid and diploid Pacific oysters. This enables them to avoid any one-off mortality problems that may be experienced occasionally due to problems within individual hatchery suppliers. Failure to do this will result in misshapen or long oysters and growth through the bag mesh. Contrary to some of the reports of mortalities following handling they regard the triploids as being generally hardier when compared to diploids in terms of summer handling and grading. It seems likely that the basis of their experience lies in the fact that triploid oysters and diploid oysters will be handled differently during the warmer summer months. Firstly, unnecessary handling during summer months is avoided as much as possible so as not to stress either type of oyster. When grading is required for diploid oysters then this is only carried out if the oysters are not close to spawning. Experience has shown that if passed over mechanised graders when in spawning condition the shock tends to induce spawning which then together with exposure to air and high summer temperatures can lead to mortalities occurring. These mortalities therefore are as a result of the reproductive state of the diploid oysters at that time. Triploids by comparison can be graded throughout the summer as they do not suffer mortalities in this way as no spawning event will occur through a shock such as grading. However, Jersey Oysters employ a different methodology when handling triploids as opposed to diploid oysters in the summer. This difference is based on the fact that triploids with their fast growth rates tend to have large amounts of frill and softer shells. Therefore two weeks prior to grading the oyster bags are turned in order to help harden the oysters; the trailer on to which the oyster bags are loaded is only filled to half the normal depth so as not to crush the shells of the oysters in the bottom bags; grading may either be carried out by hand or with the minimum amount of mechanisation possible. A grader using a water bath to soften impact is also about to be purchased in order to further reduce stress during grading for both diploid and triploid oysters. In this way the risks of causing shell damage and holes, thus allowing desiccation of the oyster, are minimised. This ensures that the shell valves do not gape during transport and lose moisture. This method ensures that the oysters are transported under minimal stress conditions so ensuring a good shelf life and minimal mortality levels. It may be that the experiences of oyster farmers who have successfully grown triploid oysters could where possible be documented and this information made available to other industry members. Industry members growing triploid oysters should be encouraged as far as possible to share their experiences and dissemination routes that might be used could include invitations to those growers to attend and present at association and industry meetings or conferences. Funding should be investigated to allow for this dissemination to take place whether through literature, site visits or presentations. With this method cytochalasin B (a blocking agent) is used to inhibit the expulsion of polar body 2 in diploid females crossed with tetraploid males. The process of producing tetraploids was described first by Guo and Allen (1994b) where cytochalasin B was used to treat the cross of a fertile triploid female with a diploid male. This new method uses the normal cross used in hatcheries to produce triploids of 2n females with 4n males but with the added addition of cytochalasin B treatment to the fertilised eggs to inhibit the expulsion of the second polar body therefore adding an extra haploid genome and producing tetraploids. This technique differs from that of Guo and Allen (1994b) in that no triploid oysters are used during the process. This method gives a direct means of introgression of genetic characters from selected diploid to tetraploid lines. Selective breeding of tetraploids is known to be slower and more complex than in diploids (Boudry and Haffray, 2006) so this new method of producing tetraploids has the advantage that desirable traits can be selected in diploids working in normal laboratory conditions, i. Thus breeding of tetraploids lines can be undertaken more easily thus leading to the possibility of producing genetically improved triploids. Investigations have been undertaken as to whether this might offer a non-patented method of producing tetraploid males for triploid production. Boudry confirmed that this method requires that you have at least one male tetraploid oyster in order to produce more tetraploid progenies. It shows that diploid eggs can produce tetraploid offspring, so that the use of larger triploid eggs is not the only way to produce tetraploids (which is the basis of Guo and Allen patent). It also appears that there are more Patents currently being processed regarding the production of tetraploid bivalves that will only make this issue more complex. This patent issue added to the need to have at least some tetraploid males to begin with would seem to suggest that it is unlikely that this method described by McCombie et al. There does however appear to be a strong demand in the French market at present for triploid Pacific oyster seed due to concerns over summer mortality problems. His comments are summarised as follows: There is good scope for increasing the percentage of triploids oysters produced by temperature methods. This would require laboratory based trials to be carried out that could then be scaled up to hatchery production. This could also be explored through a collaborative R&D and commercial arrangement; Developing these methods could well achieve triploid production rates of 95 to 100%. This method could be considered for Pacific oysters but would be considered more speculative; Beaumont was not aware of any other methods of producing sterile oysters other than triploidy. Other techniques used in aquaculture such as hormonal feminisation that is used on fish etc. It also seems unlikely that practises such as culling of slow growing larvae would have this effect.

They know that if they can find the voice of the Wind Singer erectile dysfunction prescription drugs generic viagra with fluoxetine 100/60 mg without a prescription, an ancient and mysterious instrument that stands in the centre of Aramanth erectile dysfunction diagnosis treatment order cheap viagra with fluoxetine online, they can save their people from a deadening lethargy impotence over 60 discount viagra with fluoxetine 100/60mg without prescription. Tolerance and the importance of individuality are explored in the wonderful fantasy erectile dysfunction causes stress purchase viagra with fluoxetine 100/60 mg amex, the first book of a planned trilogy erectile dysfunction drugs otc buy viagra with fluoxetine 100/60mg. The audience Dubosarsky addresses is an upper primary one but there is much in these two books that will assist secondary school teachers erectile dysfunction treatment edmonton buy viagra with fluoxetine 100/60mg with visa. The Word Spy looks at the genesis of alphabets and the growth of the English language. His extraordinary sounds to represent full stops, commas, quotation marks and exclamation marks are very amusing. There is fun to be had with word codes, anagrams, palindromes, mnemonics, pig Latin, homophones and mondegreens. Spoonerisms and Tom Swifies and so much more are available with great examples and games and activities to inspire and involve students. Both books would be notable additions to any library and valuable resources for both teachers and students. The old, weak and young were sent to the left and to their deaths in the gas chambers while those sent to the right suffered starvation and torture as well as the likely prospect of sudden death. The Wrong Boy tells the story of 16-year-old Hanna Mendal and her family who are sent to the right. His son, Karl, appears sullen and remote in front of his father but it becomes apparent he is trying to help what Jews he can and an unlikely friendship grows between the two young people. This powerful and disturbing story, which ends with the liberation of the camp, the return of Hanna to Hungary, a reunion with her sister, and a letter to Karl, should make a powerful impression upon students. The themes and forms used are varied and each poet has at least three poems so that you can start to identify the distinguishing features of that poet. The tragic loss of his companions, and his own struggle back to base against the awful cold and the poison he unwittingly consumed in the dog meat he was eating, make this a remarkable story of courage and survival. It is based on the comic book character of the same name published by Marvel Comics. The story revolves around the young and powerful, but arrogant, Crown Prince of Asgard, Thor (from ancient Norse mythology). The plot is fairly simplistic and one-dimensional, as are many of the characters, so the key to studying this film would be examining its representation of comic superheroes and mythical characters as well as its use of engaging cinematic, visual and special effects (especially were you to view the 3D version). The first play, the Devoted Friend, is very self-conscious of the process of creation, ordering wardrobes of clothes and encouraging the act of pretending, so that children develop their imagination. It uses speeches composed of sentence fragments and partial ideas to convey stories of friendship and bullying centred around a garden with songs. The Happy Prince uses puppets, songs and poems with interesting dialogue to link characters. Repetitive songs act as a chorus, not dependent on a narrator to develop the story (often the process in book adaptations). Kira is a rich, female protagonist whose aim is to save refugees attacked by pirates on the high seas. The book deals with a number of moral dilemmas, decisions relating to piracy, individual responsibility and the dubious power of the press, highlighted in sensationalised gossip columns and headlines. The thriller is compelling and easy reading with an interesting twist to complete the story. The novel is set during the Great Depression in the fictional town of Maycomb, Alabama. Six-year-old Scout and her older brother, Jem, live with their widowed father, Atticus Finch, who is the town lawyer. They have a reclusive neighbour, Boo Radley, and a friend, Dill, who visits Maycomb in the summer. It is only with the help of their neighbour, Boo, that Scout and Jem avoid paying with their lives for the bravery of their father. Students in Year 10 can appreciate the warmth and humour of the book as well as investigate its serious themes of racial equality and moral courage. His father sacrifices all in order to take him to Beijing so that he can be tutored by the best and realise his dreams. As he is torn between his love of family, his love of music and his first romantic love, the shy and sensitive Xiaochun strives to figure out who he is and who he wants to be. As we head for what we assume is a predictable conclusion, the viewer is pleasantly surprised by a truly poignant twist in the tale at the end that makes you reflect on all that you have just witnessed. This is a film about love and sacrifice, power and ambition, but most importantly it is about loyalty and the understanding of self. Another funny, quirky adventure about friendship, families and saving the world, from popular award-winning storyteller, Steven Herrick. Ellie and her friends return from a camping trip in the bush to find their families taken prisoner and their country overrun. From evading their enemies they turn to attacking them and in the process undergo significant changes. John, the main character, is obsessed with setting up his dominoes so they will topple over by pushing just one domino. The game of rugby becomes something of a metaphor for life as his friendship with the unconventional and confronting Nuala develops. In the search for an identity uniquely theirs, both characters question the expectation of their peers and the society in which they belong. Characterisation is skilful and the exploration of relationships is particularly thought-provoking. Layered with tales of mountain climbing experiences and what some would see as an adventure story, the film pivots around a key event, that of their near fatal accident on the mountain and its consequences. As the two climbers recount the events of their tragic climb on camera, the viewer is taken on a re-enacted and simulated visual journey into the precipices, ice, darkness, fear and horror of what confronted them. Viewers are held spellbound in the climactic scenes where Yates, in order to survive himself, is forced to make the decision to cut the line tying him to Simpson, knowing that this will send his already injured friend to a certain death. For the viewer, it is hard to fathom that such a horrendous and miraculous survival story is in fact true. Each chapter focuses on a different quality or role of the children and is told in a conversational style using a narrator, Milo. Kirsty Murray states that the original idea for the book was to look at all the different ways that children expressed courage and their own individual strengths. This is an essential collection for any school and features traditional verse and songs and even doggerel. The collection is a comprehensive guide to Australian identity (European) from the early days of convict settlement, through to white settlement, the rise of patriotism leading to federation and to the participation in foreign wars. It does not offer a multicultural or Indigenous perspective; however, the collection includes many well-known poets of yesteryear such as Banjo Paterson, Henry Lawson and C J Dennis alongside many lesser known poets and even some anonymous verses. At the end of each poem or song there are explanatory notes, including translation of certain slang words, biographical information about the author (if known) and the source of the original publication. The index at the end of the book is arranged according to the title of the poem/song as well as the first line. His friend, Gardo, and he have worked the dump since they were small looking for materials they can recycle and sell. The police are after them and violence is not far away as they race to break the code and solve the mystery. These characters will find their way into your heart with their bravery and courage, their humour and their resilience. Original and engaging, this multi narrated story (each boy takes a turn narrating the story and others, like the social worker and Father Juilliard, lend a hand in the telling) explores issues of poverty, injustice, corruption and friendship in the amazing setting of one of the poorest places in the world (Mulligan modelled his city on Manila and its smoking rubbish tips). Just as important as the play are the notes, with a discussion on the process of adaptation, the decisions made about characterisation, on staging the text and about set and design. Ten actors are required for this story about a boy who ends up on a ship with a group of ruffians who are seeking lost treasure. The play form is a good way to introduce students to texts they may not otherwise read. The content examines Australian identity and explores ideas about multiculturalism, history, sport and language. The first part of this memoir details the extensive work carried out by the 16-year-old and her team of helpers before she set sail. But Watson begins her story with an account of the bruising encounter she and her yacht had with a bulk carrier even before she left Australia on her voyage. Instead of weakening her resolve it strengthened it and she went on to sail unassisted around the world in 210 days. Some of the details of her journey include dealing with sleep deprivation and solitude, huge seas and numerous knockdowns in the Southern Ocean, and making Anzac biscuits on board her yacht!. The maps, photographs and glossary are useful in orientating the reader and providing insight into the demands of the voyage. Students in Years 9 and 10 will find much to admire and discuss in this biographical account, which could provide impetus for their own life writing. The Tuck family have found the fountain of youth in spring water and for them eternal life is a reality. When 10-year-old Winnie Foster stumbles into the family and a stranger seems close to exploiting the secret, the Tucks must take action to protect Winnie and the secret. This text can be read at different levels and provides excellent opportunities for classroom discussion and composing. In the first play Beatrix Potter acts as a narrator who invites her characters to act out on the stage. In the second play the characters interact with Beatrix Potter and try to explore her inspiration and why she loved animals. To achieve her goal she needs to train at the local swimming pool, a pool designated for the use of white residents only. At the heart of this film is the choice that Koorine has to make: to reject the cultural bonds she has, or continue to live a lie in order to follow her dream. Colin is sent to England by his parents when his little brother is dying of leukaemia. But the bravery and toughness of this novel means it will be a terrific text to use in Years 9 and 10.
