Quantitative genetic basis of fatty acid composition in the GIFT strain of Nile tilapia (Oreochromis niloticus) selected for high growth
Type: Journal Article
The quantitative genetic basis of fatty acid composition was examined in the Genetically Improved Farmed Tilapia (GIFT) strain of Nile tilapia selected for high breeding value for body weight and in the contemporaneous ...
Aquaculture genetics research in Egypt
Type: Conference Paper
Fish production in Egypt has significantly increased over the last few years reaching 546 000 t in 1998 compared to 306 000 t in 1988. The contribution of aquaculture in the overall fish production has increased as well ...
A simple and inexpensive fish tagging method
Type: Journal Article
In many developing countries, availability of suitable tags for use in genetics and aquaculture research has been a problem as they are often expensive and have to be imported from other countries. A simple and inexpensive ...
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 ...
Response to selection for growth in an interspecific hybrid between Oreochromis mossambicus and O. niloticus in two distinct environments
Type: Journal Article
The development of a saline tolerant tilapia strain able to grow fast is of importance in the Philippines, where 240 000 ha of brackish water ponds are available. To this end, founder hybridization between Oreochromis ...
Indirect genetic effects and inbreeding: Consequences of BLUP selection for socially affected traits on rate of inbreeding
Type: Journal Article
Social interactions often occur among living organisms, including aquatic animals. There is empirical evidence showing that social interactions may genetically affect phenotypes of individuals and their group mates. In ...
Genetic improvement of farmed tilapias: biochemical characterization of strain differences in Nile tilapia
Type: Journal Article
Four African wild strains (Egypt, Ghana, Senegal and Kenya) and four established Asian farmed strains of Nile tilapia, Oreochromis niloticus (popularly known in the Philippines as 'Taiwan', 'Thailand', 'Singapore' an ...
The Network of Tropical Aquaculture Scientists (NTAS) : past, present and future
Type: Journal Article
This article reviews the past, present and future activities of the Network of Tropical Aquaculture Scientists (NTAS), an information network for individual scientists working on tropical aquaculture, especially on genetics, ...
Survival, male morphotypes, female and male proportion, female reproductive status and tag loss in crosses among three populations of freshwater prawn Macrobrachium rosenbergii (de Man) in India
Type: Journal Article
The present study examined the variation in survival, proportion of male morphotypes, female and male proportion, female reproductive status and tag losses in nine crosses from a complete (3 × 3) diallel mating of three ...
