European Commission | TRUE-FISH R3.3: Improved protection of biodiversity, in relation to conservation of native species of tilapias in the EAC region. Annual narrative report: September 2021 to June 2022
Type: Donor Report
Tilapia aquaculture systems in EAC region are based on a handful of species, notably Oreochromis niloticus (Nile tilapia). However, there are other wild tilapia species and strains that could be potential candidate species ...
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 ...
Importance and implementation of simple and advance selective breeding programs for aquaculture species in developing countries
Type: Conference Paper
Aquaculture is predicted to play a major and ever increasing role in meeting human needs for protein. In terrestrial animal and plant species genetic improvement programs have made a substantial contribution to productivity ...
Donor-oyster derived heritability estimates and the effect of genotype X environment interaction on the production of pearl quality traits in the silver-lip pearl oyster, Pinctada maxima
Type: Journal Article
The aim of this study was to estimate donor-oyster derived heritability and genetic correlations for pearl quality traits in the silver-lipped pearl oyster, P. maxima; namely pearl size, colour, lustre, shape and complexion. ...
Abbassa Tilapia breeding program
Type: Presentation
WorldFish Genetics Workshop 2022 - ppt presentation about the Tilapia breeding program in Abbassa.
Genetic improvement programs for red tilapia Oreochromis spp in Asia
Type: Conference Paper
Red tilapia (Oreochromis spp) has become popular in Asian countries due to its greater economic value relative to Nile tilapia. As there is a growing demand for quality seed of this species, the WorldFish Center has initiated ...
Genetic improvement of freshwater prawn, Macrobrachium rosenbergii (de Man) in India 2007-2010: final report
Type: Report
Macrobrachiurn rosenbergii is one of the widely cultured freshwater prawn species globally. India was the third largest producer of this species in 2007 and its aquaculture production rose to 43,000 metric tons (t) in 2005 ...
Genetic parameters for survival during the grow-out period in the GIFT strain of Nile tilapia (Oreochromis niloticus) and correlated response to selection for harvest weight
Type: Journal Article
The aims of this study were the estimation of genetic parameters for survival rate from tagging until harvest and the evaluation of the correlated response in survival rate to selection for harvest weight in the genetically ...
Considerations about effective dissemination of improved fish strains
Type: Working Paper
Aquaculture production systems in developing countries are largely based on the use of unimproved species and strains. As knowledge and experience are accumulated in relation to the management, feeding and animal health ...
Genetically improved farmed tilapia (GIFT) selective breeding program
Type: Presentation
WorldFish Genetics Workshop 2022 - ppt presentation about the history, present and future of the GIFT tilapia selective breeding program.
