![]() ![]() Generation across the major farmed species by implementing individual or family-based ![]() Growth rate can be improved by 10% per generation and disease resistance by 15% per Is likely the best strategy for genetic improvement of most molluscs, and on average A survey of the results of currentīreeding programs in the literature show that selective breeding with inbreeding control High fecundity, self-fertilization, high genetic diversity, genetic load, high incidence ofĭeleterious mutations and segregation distortion, and critically assess their impact on theĭesign and effectiveness of selective breeding strategies. Here we review characteristics of the life history and genetics of molluscs including Intensive aquaculture and by providing a new suite of tools for genetic improvement. Understanding of the characteristics of mollusc genetics that can pose a challenge for Have the potential to revolutionize hatchery-based selective breeding by improving our Genetic improvement of broodstock through selective breeding. Species in hatcheries can secure independence from wild stocks and enables long-term The production of most farmed molluscs, including mussels, oysters, scallops, abalone,Īnd clams, is heavily dependent on natural seed from the plankton.
