Inbreeding and effective population size in the Malaysian nucleus of the GIFT strain of Nile tilapia (Oreochromis niloticus)
Type: Journal Article
A fully pedigreed population of the GIFT (Genetically Improved Farmed Tilapia) strain of Nile tilapia (Oreochromis niloticus) was established in Malaysia during 2001 and 2002. The selection program was focused on the ...
Genetic improvement and dissemination of rohu (labeo rohita, Ham.) in India
Type: Book Chapter
Experts carried out selective breeding of Rohu carp for greater harvest weight and yielded an average of 17% genetic gain per generation in 5 generations of selection.
Genetic and environmental factors affecting growth of Nile tilapia (Oreochromis niloticus) juveniles: Modelling spatial correlations between hapas
Type: Journal Article
The aim of this study was to quantify the environmental and genetic effects on early growth of Nile tilapia, Oreochromis niloticus.
Genetic improvement of Israeli blue (Jordan) tilapia, Oreochromis aureus (Steindachner), through selective breeding for harvest weight
Type: Journal Article
Genetic parameters and selection responses were obtained for harvest body weight of blue tilapia (Oreochromis aureus) from data collected over three generations in a selected population. A total of 18 194 records representing ...
Genetic variance for uniformity of harvest weight in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Competition 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 ...
Development of aquatic animal genetic improvement and dissemination programs : current status and action plans
Type: Report
WorldFish Center in collaboration with the China Academy of Fishery Sciences organized the international “Workshop on Dissemination of Improved Fish Strains: Country-Specific Action Plans” on 21-22 September (2005) in ...
Estimation of genetic change in the GIFT strain of Nile tilapia (Oreochromis niloticus) by comparing contemporary progeny produced by males born in 1991 or in 2003
Type: Journal Article
Genetic change in the Genetically Improved Farmed Tilapia (GIFT) Nile tilapia (Oreochromis niloticus) was estimated by comparing the performance of the progeny produced from cryopreserved spermatozoa from the base population ...
Genotype by environmental interaction for live weight between two production environments in the GIFT strain (Nile tilapia, Oreochromis niloticus)
Type: Conference Paper
A genotype by environmental interaction study was conducted using the live weight data collected from three discrete spawning seasons of Genetically Improved Farmed Tilapia selective breeding program in Malaysia. Two ...
Evaluation of growth performance in a diallel cross of three strains of giant freshwater prawn (Macrobrachium rosenbergii) in Vietnam
Type: Journal Article
The giant freshwater prawn (Macrobrachium rosenbergii) is one of the most important crustacean species produced in inland aquaculture in many tropical and subtropical countries worldwide. The aim of the current study was ...
Mass spawning of Oreochromis niloticus for fry production: threats and opportunities for small-scale aquaculture and selective breeding
Type: Book Chapter
Mass selection based on mass spawning can present a feasible and low-cost selective breeding scheme. In mass spawning, however, mating is not controlled and a small number of breeding individuals may account for a ...
