Genetic evaluation of growth and survival at 6 weeks old fry of Egyptian Nile Tilapia (Oreochromis niloticus) between improved Abbassa and commercial Manzala strains in a diallel crossing
Type: Journal Article
The main objectives of this study were to evaluate growth performance and estimate line crossing parameters of improved Abbassa tilapia strain and a commerciall Manzala strain within a complete diallel cross at 6 weeks old ...
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
Type: Journal Article
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 ...
Report of the genetics team meeting of the CGIAR Research Program on Livestock and Fish. Kenya, 30-31 July 2012
Type: Report
The CGIAR Research Program on Livestock and Fish started in January 2012. It aims to increase the productivity of small-scale livestock and fish systems in sustainable ways, making meat, milk and fish more available and ...
Manual on genetic improvement of farmed tilapia (GIFT) research methodologies
Type: Manual
Gathering and recording of biological data vital to experiments in a genetic improvement program should be carried out with efficiency, precision and accuracy. This is important in order to avoid marking erroneous conclusion ...
Applied genetics of tilapias
Type: Working Paper
The present world production of tilapias is relatively low, despite their high potential for aquaculture. Most research efforts towards their husbandry have been aimed at solving the major problem in tilapia culture, ...
Genetics of adaptation in rainbow trout: a multi disciplinary approach
Type: Conference Paper
Ability of fish to adapt to changing environments and stressors is a key trait for breeders, especially when they sell eggs or young fish all over the world. So far, this ability has not been introduced in any breeding ...
Individual growth monitoring of European sea bass larvae by image analysis and microsatellite genotyping
Type: Journal Article
The aims of the present study were to develop non-lethal methods to identify individual fish larvae and post-larvae before tagging and accurately follow their growth characteristics. European sea bass (Dicentrarchus labrax) ...
Genomics in marine monitoring: New opportunities for assessing marine health status
Type: Journal Article
This viewpoint paper explores the potential of genomics technology to provide accurate, rapid, and cost efficient observations of the marine environment. The use of such approaches in next generation marine monitoring ...
Preservation of genetic diversity in restocking of the sea cucumber Holothuria scabra investigated by allozyme electrophoresis
Type: Journal Article
Population genetics analyses should be considered when releasing hatchery-produced juveniles of the sea cucumber Holothuria scabra when spawners from nonlocal populations are used. In New Caledonia, within-region genetic ...
PmPPAF is a pro-phenoloxidase activating factor involved in innate immunity response of the shrimp Penaeus monodon
Type: Journal Article
One of the major steps in the innate immune response of shrimp includes the activation of serine proteinases of the pro-phenoloxidase pathway by the prophenoloxidase activation enzyme (PPAF). In this study, the cDNA encoding ...
