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 ...
Farm-economics of genetically improved carp strains in major Asian countries and carp seed price policy model
Type: Journal Article
The study has conducted the micro level analysis of hatchery operators, fishseed-rearing farmers and carp farmers with respect to their socio-economic characteristics, infrastructural development, husbandry practices and ...
From drawing board to dining table: the success story of the GIFT project
Type: Journal Article
As compared to crops and livestock, the genetic enhancement of fish is in its infancy. While significant progress has been achieved in the genetic improvement of temperate fish such as salmonids, no efforts were made until ...
Socioeconomics of disseminating genetically improved Nile tilapia in Asia: an introduction
Type: Journal Article
The International Center for Living Aquatic Resources Management (ICLARM) undertook a major strategic research project known as the "Genetic Improvement of Farmed Tilapias" (GIFT), with funding support from the United ...
Genetics and the study of fisheries connectivity in Asian developing countries.
Type: Journal Article
The paper presents a brief summary of the available methods to determine connectivity using genetic markers and two examples where they have been applied in Southeast Asia. Recommendations for the more efficient conduct ...
Selective breeding for increased body weight in a synthetic breed of Egytian Nile tilapia, Oreochromis niloticus: response to selection and genetic parameters
Type: Journal Article
Selection for harvest weight was performed in a fully pedigreed synthetic line of Nile tilapia (Oreochromis niloticus) in Egypt for two generations. Records were available over three spawning seasons (2002, 2003 and 2004) ...
Production priorities overshadow genetic quality at African fish hatcheries
Type: Journal Article
Based largely on FAO programs that address rural poverty, small-scale hatcheries have been developed in Africa to produce catfish and tilapia fingerlings. Production practices that fail to maintain genetic diversity, ...
Evaluation of the carcass and commercial characteristics of carps
Type: Journal Article
The role of carcass evaluation techniques in aquaculture research programs, especially in genetics, breeding, production management, feeding and nutrition, cannot be overemphasized. Knowledge of production efficiencies and ...
Baseline biochemical and genetic profiles of four fishes from the River Nile
Type: Journal Article
Six enzyme systems coding for 10 loci and 6 proteins were examined in the blood of Polypterus senegalus, Clarias lazera, Tilapia nilotica and Protopterus annectens, using electrophoresis. Six loci were polymorphic in all ...
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 ...
