A Quantitative Genetic Analysis Of Commercial Traits In Polyploid Crassostrea Virginica, With An Evaluation Of Strategies For Genetic Improvement Of Triploids, Joseph L. Matt
Dissertations, Theses, and Masters Projects
Triploids are a popular product in commercial oyster aquaculture and make up most of the hatchery-produced Crassostrea virginica farmed in the Chesapeake Bay. Despite their importance to commercial aquaculture, the potential of genetically improving triploid C. virginica from selective breeding and breeding strategies for their improvement had not been evaluated. In this dissertation, the prospect of improving triploid C. virginica through selective breeding was assessed with a quantitative genetic analysis from a field test, and breeding strategies for genetically improving triploids were compared by computer simulation. Heritability and genetic correlations involving commercial traits in triploids, including mass mortality associated with …
Stock Composition Of Striped Marlin (Kajikia Audax) In The Central North Pacific Ocean Inferred By Analyses Of Genome-Wide Molecular Markers, Jackson Martinez
Stock Composition Of Striped Marlin (Kajikia Audax) In The Central North Pacific Ocean Inferred By Analyses Of Genome-Wide Molecular Markers, Jackson Martinez
Dissertations, Theses, and Masters Projects
Relative to many highly migratory fishes, Striped Marlin, Kajikia audax, exhibit considerable stock structure. At least four genetically distinct stocks of Striped Marlin have been delineated in the Pacific and Indian oceans, although stock composition in the central North Pacific (CNP) remains unclear and the presence of an additional stock in the North Pacific has been suggested in two recent studies. The goals of this research were to clarify the number of Striped Marlin stocks in the North Pacific and utilize temporal sampling to better understand the stock dynamics of Striped Marlin exploited by the Hawaii-based pelagic longline fishery (HBPLLF). …
