Genomic selection strategies to overcome genotype by environment interactions in biosecurity-based aquaculture breeding programs
Published 2025-01-01“…Fortunately, genomic selection shows promise in improving genetic gain by taking within-family variance into account. Stochastic simulation was employed to evaluate genetic gain and G × E trends in BS for improving the body weight of L. vannamei, considering selective genotyping strategies for test group (TG) at a commercial farm environment (CE), the number individuals of the selection group (SG) genotyped at nucleus breeding center (NE), and varying levels of G × E. …”

A Metapopulation Model to Assess Water Management Impacts on the Threatened Australian Lungfish, <i>Neoceratodus forsteri</i>
Published 2025-01-01“…As this long-lived species (at least 77 years) has delayed maturity (mature at 10 years), field monitoring alone will not be enough to inform the challenge of ensuring sustainable populations. A stochastic metapopulation model was developed for the Burnett River (Southeast Queensland, Australia), an important habitat for the lungfish that is a highly regulated system with extensive water infrastructure. …”
