Growth and survival rate of three genetic groups fed 28% and 34% protein diets
Type: Journal Article
The strain by nutrition interaction in body weight and survival rate was examined by testing three genetic groups (Selection and Control lines of the GIFT strain, and Red tilapia) at two levels of protein in the diet (28% ...
Genetic improvement of farmed aquatic animals at the WorldFish Center
Type: Brief
Aquaculture is the fastest growing food production sector in the world today, supplying half of global fish consumption. Production from capture fisheries has stagnated and is unable to meet the anticipated growth in demand. ...
Genotype by production environment interaction in the GIFT strain of Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Three 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 ...
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 ...
GIFT tilapia raise culture efficiency in Sri Lanka
Type: Journal Article
The wide distribution and ongoing improvement of GIFT tilapia in Sri Lanka is raising the living standards of poor people and contributing to gender equality through employment for women in rural areas. So far, the GIFT ...
Genetics of flesh quality in fish
Type: Journal Article
Genetic improvement has led to substantial increase in productivity in farmed animals and in tropical fin fish, this is evident in tilapia. The GIFT (Genetically Improved Farmed Tilapia) strain of Nile tilapia (Oreochromis ...
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 ...
Correlated response in fillet weight and yield to selection for increased harvest weight in genetically improved farmed tilapia (GIFT strain), Oreochromis niloticus
Type: Journal Article
A data set consisting of 5532 slaughter records collected over three generations from a selection program for increased harvest body weight in the GIFT strain of Nile tilapia (Oreochromis niloticus) was used to estimate ...
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 ...
Breeding for robustness: Investigating the genotype-by-environment interaction and micro-environmental sensitivity of Genetically Improved Farmed Tilapia (Oreochromis niloticus)
Type: Journal Article
The objectives of this study were (i) to quantify the degree of G x E by assessing the growth performance of Genetically Improved Farmed Tilapia (GIFT) across three countries (Malaysia, India and China) and (ii) to quantify ...
