Breeding program requirements in developing countries may differ depending on circumstances

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 the application of mass, cohort, ...

Can sexual dimorphism and body shape be altered in Nile tilapia (Oreochromis niloticus) by genetic means?

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 of body size. Body weight, length, ...

Estimation of genetic change in the GIFT strain of Nile tilapia (Oreochromis niloticus) by comparing contemporary progeny produced by males born in 1991 or in 2003

Genetic change in the Genetically Improved Farmed Tilapia (GIFT) Nile tilapia (Oreochromis niloticus) was estimated by comparing the performance of the progeny produced from cryopreserved spermatozoa from the base population with that produced by freshly ...

Genetic improvement of farmed tilapias: composition and genetic parameters of a synthetic base population of Oreochromis niloticus for selective breeding

The present study is based on data recorded from fish of the third generation of the GIFT project (Genetic Improvement of Farmed Tilapias). The objective of the study was to compose a synthetic base population of Nile tilapia for further selective ...

Genetic improvement with specific reference to tilapia genetic resources in Africa and their use in aquaculture - potential benefits and risks.

In comparison to the rest of the world, aquaculture in Africa is fairly insignificant. The continent as a whole contributed a mere 0.9 per cent (404 571 t) to the total world aquaculture production in 2000. The African continent, however, exhibits ...

Genetic parameter and genotype by environment interaction for body weight of Oreochromis shiranus

Genetic and phenotypic parameter estimates for tagging and harvest body weights were obtained from the F1 base (377 offspring of 59 full-sib families), F2 (1241 offspring of 52 full- and 33 half-sib families) and F3 (1052 offspring of 55 full- and 25 half ...
