Quantitative genetic parameter estimates for body and carcass traits in a cultured stock of giant freshwater prawn (Macrobrachium rosenbergii) selected for harvest weight in Vietnam
(2013)Type: Journal ArticleBenefits derived from selective breeding have been demonstrated in livestock and in some fish species, but by contrast, there have been few systematic selection programs reported for shrimps. Improving growth rate has been ... -
Relative performance of two Nile tilapia (Oreochromis niloticus Linnaeus) strains in Egypt: The Abbassa selection line and the Kafr El Sheikh commercial strain
(2013)Type: Journal ArticleThe Abbassa selection line (developed by selective breeding) and the Kafr El Sheikh commercial strain (widely used in Egypt), both Oreochromis niloticus, were compared at two stocking densities (two and four fish m-2). ... -
Selective breeding for increased body weight in a synthetic breed of Egytian Nile tilapia, Oreochromis niloticus: response to selection and genetic parameters
(2009)Type: Journal ArticleSelection for harvest weight was performed in a fully pedigreed synthetic line of Nile tilapia (Oreochromis niloticus) in Egypt for two generations. Records were available over three spawning seasons (2002, 2003 and 2004) ... -
Selective breeding in fish and conservation of genetic resources for aquaculture
(2012)Type: Journal ArticleTo satisfy increasing demands for fish as food, progress must occur towards greater aquaculture productivity whilst retaining the wild and farmed genetic resources that underpin global fish production. We review the main ... -
Strain comparisons in aquaculture species: a manual
(2013)Type: ManualWhen different strains or breeds of a particular species are available, the best choice is seldom immediately obvious for producers. Scientists are also interested in the relative performance of different strains because ... -
Survival, male morphotypes, female and male proportion, female reproductive status and tag loss in crosses among three populations of freshwater prawn Macrobrachium rosenbergii (de Man) in India
(2015)Type: Journal ArticleThe present study examined the variation in survival, proportion of male morphotypes, female and male proportion, female reproductive status and tag losses in nine crosses from a complete (3 × 3) diallel mating of three ... -
Transgenic fish: risks and benefits
(2008)Type: Journal ArticleAdvocates of transgenesis consider it an effective means of improving the productivity of aquatic animals. Opponents see it as a threat to both the environment and human health. This is a challenging area because important ...
