Genetic and non-genetic indirect effects for harvest weight in the GIFT strain of Nile tilapia (Oreochromis niloticus)
(2016)Type: Journal ArticleThe main objective of this study was to quantify the heritable variation for growth rate of GIFT, and the contribution of IGEs to this heritable variation. Here we describe the experiment conducted for this purpose, and ... -
Genetic parameters for uniformity of harvest weight and body size traits in the GIFT strain of Nile tilapia
(2016)Type: Journal ArticleAnimal breeding programs have been very successful in improving the mean levels of traits through selection. However, in recent decades, reducing the variability of trait levels between individuals has become a highly ... -
Genetic variance for uniformity of harvest weight in Nile tilapia (Oreochromis niloticus)
(2016)Type: Journal ArticleCompetition for resources is common in aquaculture, which inflates the variability of fish body weight. Selective breeding is one of the effective approaches that may enable a reduction of size variability (or increase in ... -
Genotype by production environment interaction in the GIFT strain of Nile tilapia (Oreochromis niloticus)
(2012)Type: Journal ArticleThree discrete generations of GIFT fish (Nile tilapia strain, Oreochromis niloticus; a total of 10,065 fish with pedigree and phenotypic information) were tested in pond and cage culture environments to determine genotype ... -
Indirect genetic effects and inbreeding: Consequences of BLUP selection for socially affected traits on rate of inbreeding
(2014)Type: Journal ArticleSocial interactions often occur among living organisms, including aquatic animals. There is empirical evidence showing that social interactions may genetically affect phenotypes of individuals and their group mates. In ...
