Type: Journal Article
A data set consisting of 5532 slaughter records collected over three generations from a selection program for increased harvest body weight in the GIFT strain of Nile tilapia (Oreochromis niloticus) was used to estimate ...
Effect of garlic, Echinacea, organic green and vet-yeast on survival, weight gain and bacterial challenge of overwintered Nile Tilapia fry (Orechromis niloticus)
Type: Journal Article
The purpose of this study was to examine the effect of some immunostimulants and probiotics on the survival rate, final weight, and disease resistance of overwintered tilapia fry. There were five treatments: T1 (control) ...
Inbreeding and effective population size in the Malaysian nucleus of the GIFT strain of Nile tilapia (Oreochromis niloticus)
Type: Journal Article
A fully pedigreed population of the GIFT (Genetically Improved Farmed Tilapia) strain of Nile tilapia (Oreochromis niloticus) was established in Malaysia during 2001 and 2002. The selection program was focused on the ...
Benefits and challenges of applying outcome mapping in an R4D project

The overall objective of the project was to enhance fish production from seasonally flooding areas and irrigation systems using a collective approach to fish culture. The project sought to examine the institutions necessary ...
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 ...
Fishing for private expertise
