Due to its popularity as a food fish, rapid growth and wide environmental tolerances, barramundi, Lates calcarifer, production levels are increasing worldwide and breeding programs are currently being considered and implemented throughout Asia and Australia. However, for selective breeding programs to be effective, it is essential to have information on genetic parameters such as heritability and genetic correlations of traits, as well as on how families perform relative to each other over the culture cycle in single or in multiple environments (ti). Genetic parameters and G×E interactions for barramundi traits (namely weight (W), standard length (Ls), body depth (BD), Fulton's condition fac..View full abstract

Thanks to numerous suggestions from the anonymous reviewers who helped to improve the quality of this manuscript. We thank Javier M. Martinez and Dr. Leonie Valentine for assistance in animal husbandry and laboratory work associated with experiment 3. Sampling and measurement of experimental fish for experiment 3 were greatly aided by the help of Christian de Santis, James Newton, Erin McGinty, Emmanuelle Botte and Leonie Valentine. Dr. Fengduo Hu (CSIRO) and Dr. Alastair Wilson (The University of Edinburgh) are thanked for gently providing assistance in outlining the animal models. This study was partly funded by Australian Research Council Linkage (www.arc.gov.au) grant LP0990606, which supported J.A. Domingos' PhD scholarship.
