Potential applications of reproductive and molecular genetic technologies in the selective breeding of aquaculture species
Type: Conference Paper
The use of reproductive and genetic technologies can increase the efficiency of selective breeding programs for aquaculture species. Four technologies are considered, namely: marker-assisted selection, DNA fingerprinting, ...
Genetic improvement of farmed tilapias: Genetic parameters for body weight at harvest in Nile tilapia (Oreochromis niloticus) during five generations of testing in multiple environments
Type: Journal Article
The main objective of this paper was to report more reliable estimates of the genetic variation and the genotype by test environment interaction for harvest body weight in the GIFT population in the Philippines than could ...
Breeding program requirements in developing countries may differ depending on circumstances
Type: Book Chapter
Aquaculture in developing countries is largely based on unimproved fish strains. There is ample evidence indicating the potential of genetic improvement programs and a range of selection methods may be used. Examples of ...
Quantitative genetic basis of fatty acid composition in the GIFT strain of Nile tilapia (Oreochromis niloticus) selected for high growth
Type: Journal Article
The quantitative genetic basis of fatty acid composition was examined in the Genetically Improved Farmed Tilapia (GIFT) strain of Nile tilapia selected for high breeding value for body weight and in the contemporaneous ...
Genetic parameters and correlated responses in female reproductive traits in the GIFT strain
Type: Journal Article
The aim of this study was to examine genetic variation in reproductive traits and to estimate correlated responses in such traits to selection for high growth rate in the GIFT strain of Nile tilapia (Oreochromis niloticus).
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 improvement of carp reduces poverty, hunger in Asia
Type: Journal Article
Breeding programs for carp species carried out in a number of Asian countries have delivered genetically fast growing strains to farmers and producers. The economic benefits resulting from the programs are substantial. The ...
A comparison of communal and separate rearing of families in selective breeding of common carp (Cyprinus carpio): Estimation of genetic parameters
Type: Journal Article
The objective of this study was to investigate ways of improving the selective breeding program for growth related traits in common carp in Vietnam. A base population was established from six carp stocks following a single ...
Accounting for genotype by environment interaction in economic appraisal of genetic improvement programs in common carp Cyprinus carpio
Type: Journal Article
In this study we examine effects of genotype by environment (G×E) interaction due to re-ranking and scaling effects on economic benefit (EB) and benefit to cost ratio (BCR) from a genetic improvement program in common carp ...
