This book was released on 2008-02-13 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mass oyster mortalities have been known for many years throughout the world, but no strictly pathological explication has been found. This book describes how environmental influences, reproduction, stress, genetics, pathogens and temperature contribute to oyster summer mortality in France. An interaction model is derived from the results and recommendations are made for forecasting and managing risk factors.

This book was released on 2009 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summer mortality of farmed Pacific oysters causes financial losses for shellfish growers, and selective breeding to improve survival of offspring is a promising way to reduce losses. This dissertation has two objectives to assist the development of tools for use in selective breeding programs. Objective 1: Identify candidate genes for selection and use in predictive assays by examining the transcriptome response to heat shock in gill of heat-shocked (40°C, 1 h) oysters and comparing gene transcription between families with high (>65%) or low (

Download or read book Spawning Mediated Responses of Pacific Oyster Crassostrea Gigas written by Yan Li and published by LAP Lambert Academic Publishing. This book was released on 2009-11 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oyster mortality in summer is a global concern for the aquaculture industry. This issue can be getting worse and worse with global warming. Yan investigated the synergetic effect of spawning, food supply, pathogen and temperature on oyster morality in the laboratory and field. The results demonstrate that energy depletion during spawning compromises the metabolic and health status of oysters, leading to a possible mortality in summer for post-spawning oysters. This research contributes to our understanding of the mechanism of oyster mass mortality, and the results can be applied to the management and development of oyster aquaculture in Australia and overseas.

This book was released on 2011 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation develops mixed family selection for Pacific oysters using marker-based pedigree reconstruction. It focuses on improving the efficiency of parentage assignment, determining the optimum life stage to mix oyster families for rearing and selection, comparing mixed-family and separate-family selective breeding in the field, and applying the mixed method to estimate the heritability of shell shape. We developed novel computer software, P-LOCI (available at http://marineresearch.oregonstate.edu/genetics/PLOCI.html), which identifies the most efficient set of codominant markers for assigning parentage, accounting for marker linkage, mating design, null alleles and genotyping error, and found that the most efficient group of loci for assignment is not necessarily comprised of the top individually ranked loci, or best for all populations. We determined the optimum time to mix oyster families for rearing and selection in the field; overall, planting size is the most prudent time to mix families for MFS, due to high variability in family representation produced during larval and nursery stages. Mixing families at stages earlier than this for selection on field traits would require pre-planting genotyping of large samples for estimation of initial family representation, which would add substantial cost, or other special considerations. Rearing mixed family groups of oysters in the field yielded very similar results to rearing the same families separately, (r = 0.817 for two-site average individual weight at harvest), demonstrating it is unlikely associative effects are of great importance in the Pacific oyster. Our results show that the mixed method was well-suited for individual traits and walk-back selection, but would incur higher costs than the separate method to estimate survival with lower precision. Finally, we utilized the mixed method to estimate the heritability of shell shape using midparent-offspring regression; we estimated shell depth heritability as 0.404 ± 0.14 and shell width as 0.287 ± 0.11, nearly equal to the only other study for the Pacific oyster, demonstrating potential for selective breeding on these traits in this U.S. population, and similar results between methods. Overall, we found that mixed-family rearing is viable for Pacific oyster breeding, given some important restrictions.
