A comparison of communal and separate rearing of families in selective breeding of common carp (Cyprinus carpio): Estimation of genetic parameters
(2011)Type: Journal ArticleThe 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 ... -
A comparison of communal and separate rearing of families in selective breeding of common carp (Cyprinus carpio): Responses to selection
(2013)Type: Journal ArticleThe genetic response in growth traits in a selection program for increased harvest weight in a common carp population in Vietnam is reported. A base population (G0) was established from six carp stocks using single pair ... -
A comparison of GIFT and red tilapia for fillet yield and sensory attributes of flesh quality assessed by trained panel
(2006)Type: Conference PaperTilapia 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 ... -
Accounting for genotype by environment interaction in economic appraisal of genetic improvement programs in common carp Cyprinus carpio
(2008)Type: Journal ArticleIn 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 ... -
Breeding program requirements in developing countries may differ depending on circumstances
(2007)Type: Book ChapterAquaculture 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 ... -
Can sexual dimorphism and body shape be altered in Nile tilapia (Oreochromis niloticus) by genetic means?
(2007)Type: Journal ArticleThe 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 ... -
Comparative performance of four red tilapia strains and their crosses in fresh and saline water environments
(2010)Type: Journal ArticleA complete diallel cross involving four strains of red tilapia (Oreochromis spp.) from Malaysia, Stirling, Taiwan and Thailand was performed with the aim to establish a foundation population for genetic improvement. The ... -
Considerations about effective dissemination of improved fish strains
(2012)Type: Working PaperAquaculture 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 ... -
Considerations about effective dissemination of improved fish strains (in Arabic)
(2014)Type: Working PaperAquaculture 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 ... -
Correlated response in fillet weight and yield to selection for increased harvest weight in genetically improved farmed tilapia (GIFT strain), Oreochromis niloticus
(2010)Type: Journal ArticleA 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 ... -
Establishment of a satellite nucleus of the GIFT strain at Rajiv Gandhi Center for Aquaculture (RGCA) to support tilapia production in India
(2011)Type: Conference PaperRajiv Gandhi Center for Aquaculture (RGCA), India was interested in obtaining the Genetically Improved Farmed Tilapia (GIFT strain) for aquaculture in the country. Discussions were made and joint proposal was developed ... -
Estimates of strain additive and non-additive genetic effects for growth traits in a diallel cross of three strains of giant freshwater prawn (Macrobrachium rosenbergii) in Vietnam
(2010)Type: Journal ArticleAdditive genetic, heterotic and strain reciprocal effects were estimated using a diallel cross of two local wild strains of the giant freshwater prawn (Macrobrachium rosenbergii) in Vietnam (Dong Nai and Mekong) and a third ... -
Evaluation of growth performance in a diallel cross of three strains of giant freshwater prawn (Macrobrachium rosenbergii) in Vietnam
(2009)Type: Journal ArticleThe 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 ... -
Flesh characteristics: estimation of genetic parameters and correlated responses to selection for growth rate in the GIFT strain
(2014)Type: Journal ArticleGenetically improved farmed tilapia (GIFT) has undergone ten generations of selection for harvest body weight in Malaysia, but there have been no reports on genetic parameters for flesh characteristics for this strain. In ... -
Fundamental considerations about design and sample size in strain comparisons and their implications
(2011)Type: Journal ArticleWell-known formulae for the calculation of the necessary number of animals in strain comparisons are presented. Their use is illustrated with an example with fish. Use of the formulae in the planning and design of strain ... -
Genetic analysis of the GIFT strain (Nile Tilapia, Oreochromis niloticus) in Malaysia
(2010)Type: Conference PaperThe Genetically Improved Farmed Tilapia (GIFT) strain is well known worldwide because of its high performance. A first phase of the project ended in 1997 after five generations of selection. In 2002, the GIFT population ... -
Genetic evaluation of a complete diallel cross involving three populations of freshwater prawn (Macrobrachium rosenbergii) from different geographical regions of India
(2011)Type: Journal ArticleEstimates of additive genetic, reciprocal and average heterosis effects were obtained from a three by three complete diallelcross experiment for giant freshwater prawn Macrobrachium rosenbergii. The data were generated in ... -
Genetic improvement and dissemination of rohu (labeo rohita, Ham.) in India
(2007)Type: Book ChapterExperts 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
(2008)Type: Journal ArticleBreeding 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 ... -
