Investment Appraisal of Genetic Improvement Programs in Nile tilapia (Oreochromis Niloticus)
Type: Journal Article
The economic benefit derived from a genetic improvement program with Nile tilapia (Oreochromis niloticus) was examined from a national perspective. An industry structure was assumed whereby the genetic improvement program ...
Can sexual dimorphism and body shape be altered in Nile tilapia (Oreochromis niloticus) by genetic means?
Type: Journal Article
The objective of this study was to estimate genetic parameters in GIFT (Genetically Improved Farmed Tilapia), especially focusing on the genetic correlation between trait expressions in both sexes and among measurements ...
Performance of the Genetically Improved Farmed Tilapia (GIFT) strain over ten generations of selection in Malaysia
Type: Journal Article
A selection programme using Best Linear Unbiased Prediction (BLUP) method for the estimation of genetic merit was implemented by the Department of Fisheries Malaysia (DOF) in collaboration with the WorldFish Centre. This ...
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 ...
A comparison of GIFT and red tilapia for fillet yield and sensory attributes of flesh quality assessed by trained panel
Type: Conference Paper
Tilapia is a tropical freshwater fish, predicted to become the largest aquaculture production in the world, after carps, shrimp and salmonids, in the present century (Fitzsimmons, 2000). In Malaysia 85 per cent of the ...
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 ...
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
Type: Journal Article
The 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 ...
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 ...
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).
Genetic improvement programs for aquaculture species in developing countries: prospects and challenges
Type: Conference Paper
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 ...
