This book was released on 2021 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Native species are increasingly chosen for aquaculture expansion to avoid negative environmental impacts associated with the introduction of foreign species. However, the culture of native species is not without risks, as interbreeding with wild populations and can impact naturally occurring genetic diversity and population structure. The risk of adverse impacts depends, among other factors, on the frequency of interbreeding and genetic diversity of hatchery produced animals. Thus, cultured stocks that reach sexual maturity prior to harvest and have reduced genetic diversity because of small effective broodstock size, Nb, are particularly risky. Here, we evaluated both factors, first by establishing age and size at maturity and second, by determining the distribution of reproductive success and Nb in a voluntary mass spawn of purple hinged rock scallop, Crassadoma gigantea. Age and size at first maturation were determined by repeat sampling of a known age cohort grown in Dabob Bay WA for 25 months. To establish the effects of local environment on first maturation additional scallops were deployed in Totten Inlet, Dabob Bay, and Neah Bay for ten months and sampled once at the end of growout. Size and age at first maturation was 55.2 mm shell height and 25.1 months of age, well before the projected harvest size and age for cultured C. gigantea. The additive effect of age and size produced the most accurate prediction of first maturation in C. gigantea, and there was a significant effect of environment on first maturation suggesting that under optimal conditions first maturation could be even earlier than our size and age prediction. To determine the distribution of reproductive success in a mass spawn of cultured C. gigantea, scallops were deployed at the three Washington State sites were sequenced using restriction site-associated DNA sequencing to identify SNPs for parentage assignment in COLONY. Three methods were then used to calculate the Nb from sibship assignments (COLONY), parentage assignment without parents (PwoP) and linkage disequilibrium (LDNe). A total of 408 loci were identified for parentage analysis and offspring were assigned to 74.5% of candidate parents at one or more sites. Survival was family specific, as Nb was significantly different across sites and Nb/N ratios were significantly lower than 1.00 at all sites (Totten Inlet=0.33, Dabob Bay=0.26, Neah Bay=0.15). Low Nb/N ratios suggest a loss of genetic diversity in the hatchery which is worsened by mortality on during growout and are an important consideration when determining the risk of genetic diversity loss in wild populations in the event of interbreeding. Unless wild population Ne/N ratios are orders of magnitude lower than their cultured conspecifics than escapes will reduce the genetic diversity of wild populations. Our study determined that interbreeding between cultured and wild C. gigantea is possible, but the magnitude of this risk is reduced by the likely protandry and skewed sex ratio of young C. gigantea. In addition, increasing the number of broodstock used in each spawn, equalizing parental contributions prior to fertilization and using partial or full factorial spawn designs will help increase the Nb of cultured C. gigantea.

Download or read book Shellfish Processing and Preservation written by Nalan Gökoğlu and published by Springer Nature. This book was released on 2021-01-04 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shellfish is a broad term that covers various aquatic mollusks, crustaceans and echinoderms that are used as food. They have economic and ecological importance and have been consumed as food for centuries. Shellfish provide high quality protein with all the dietary amino acids essential for maintenance and growth of the human body. Shellfish are a major component of global seafood production, with shellfish aquaculture rapidly growing in recent years. There are many different processing methods used across the world. Shellfish are very perishable foods and must be preserved just after catching or harvesting. This makes the preservation of seafood a critical issue in terms of quality and human health. To date there have been a number of books on seafood processing and preservation, but all of them have been mostly focused on fish. Shellfish Processing and Preservation is the first reference work to focus specifically on shellfish, providing comprehensive coverage of the production methods, biological makeups and preservation methods of all major shellfish species. Individual sections focus on crustaceans such as shrimps and prawns, crabs and lobsters plus molluscans including mussels, scallops and oysters. Cephalopods such as squid and octopus are also covered in depth. For each species processing and preservation methods such as chilling, freezing, canning and curing are examined, plus the important safety aspects specific to each shellfish type. Shellfish Processing and Preservation is an essential publication for any researchers or industry professionals in search of a singular and up-to-date source for the processing and preservation of shellfish.
Download or read book Seafoods Chemistry Processing Technology and Quality written by Fereidoon Shahidi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seafoods are important sources of nutrients for humans. Proteins and non protein nitrogenous compounds play an important role in the nutritional value and sensory quality of seafoods. Consumption of fish and marine oils is also actively encouraged for the prevention and treatment of cardio vascular diseases and rheumatoid arthritis. Highly unsaturated long-chain omega-3 fatty acids are regarded as the active components of marine oils and seafood lipids. The basic chemical and biochemical properties of seafood proteins and lipids, in addition to flavour-active components, their microbiological safety and freshness quality, are important factors to be considered. A presentation of the state-of-the-art research results on seafoods with respect to their chemistry, processing technology and quality in one volume was made possible by cooperative efforts ofan international group of experts. Following a brief overview, the book is divided into three sections. In Part 1 (chapters 2 to 8) the chemistry of seafood components such as proteins, lipids, flavorants (together with their properties and nutritional significance) is discussed. Part 2 (chapters 9 to 13) describes the quality of seafoods with respect to their freshness, preservation, micro biological safety and sensory attributes. The final section of the book (chapters 14 to 16) summarizes further processing of raw material, underutilized species and processing discards for production of value added products.

This book was released on 2011-06-15 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global market for seafood products continues to increase year by year. Food safety considerations are as crucial as ever in this sector, and higher standards of quality are demanded even as products are shipped greater distances around the world. The current global focus on the connection between diet and health drives growth in the industry and offers commercial opportunities on a number of fronts. There is great interest in the beneficial effects of marine functional compounds such as omega-3 polyunsaturated fatty acids. Seafoods are well-known as low calorie foods, and research continues into the nutritional effects on, for example, obesity and heart disease. In addition, by-products of marine food processing can be used in nutraceutical applications. This book is a resource for those interested in the latest advances in the science and technology of seafood quality and safety as well as new developments in the nutritional effects and applications of marine foods. It includes chapters on the practical evaluation of seafood quality; novel approaches in preservation techniques; flavour chemistry and analysis; textural quality and measurement; packaging; the control of food-borne pathogens and seafood toxins. New research on the health-related aspects of marine food intake are covered, as well as the use of seafoods as sources of bioactives and nutraceuticals. The book is directed at scientists and technologists in academia, government laboratories and the seafood industries, including quality managers, processors and sensory scientists.
Download or read book Major Evolutionary Radiations written by Paul D. Taylor and published by Clarendon Press. This book was released on 1990 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique volume takes a close look at patterns of evolutionary change responsible for the astounding diversity of life and the major radiations seen in many taxonomic groups. Evidence from the fossil record shows that this process has not occurred at an even rate. Rather, relatively short but highly active periods of evolution have yielded the multiplication of species and morphological divergences, such as the emergence of flowering plants during the late Cretaceous. The contributors to this work, all recognized authorities in their fields, discuss general aspects of major radiations, and then focus on evolution in taxonomic groups with ample fossil records. The book is an important complement to the literature of extinction and paleontology, and will be read with interest by paleontologists and evolutionary biologists alike.
