Perspectives from Agriculture: Advances in livestock breeding-Implications for aquaculture genetics
Type: Journal Article
In this paper we present livestock breeding developments that could be taken into consideration in the genetic improvement of farmed aquaculture species, especially in freshwater fish. Firstly, the current breeding objective ...
Restocking and stock enhancement of coastal fisheries: Potential, problems and progress
Type: Journal Article
The demand for fish is expected to rise substantially by 2020. Although aquaculture must provide much of the additional fish, it remains to be seen whether restored or enhanced capture fisheries can also help fill the ...
Mating systems and male reproductive success in Nile tilapia (Oreochromis niloticus): a microsatelite analysis
Type: Journal Article
Fry production in Nile tilapia, Oreochromis niloticus is typically achieved by mass spawning of males and females stocked in large hapas suspended in ponds. In such spawning aggregations, territorial behavior and reproductive ...
Heritability estimates and response to selection for growth of Nile tilapia (Oreochromis niloticus) in low-input earthen ponds
Type: Journal Article
This study presents results of two generations of selection (G1 and G2) for growth of Nile tilapia. The selection environment consisted of earthen ponds which were fertilized daily with 50 kg dry matter (dm)/ha chicken ...
Genetic parameter and genotype by environment interaction for body weight of Oreochromis shiranus
Type: Journal Article
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 ...
