Response to bi-directional selection for frequency of early maturing females in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
The present study was carried out to investigate a simple method for recording the occurrence of early maturing females in Nile tilapia at a fixed time after stocking and to estimate the response to bi-directional selection ...
Approaches to national fish breeding programs: pointers from a tilapia pilot study
Type: Journal Article
Details are given of a framework for developing breeding programmes using experience from the Genetic Improvement of Farmed Tilapias project which focussed on Nile tilapias (Oreochromis niloticus ). The following aspects ...

Genetic improvement of farmed tilapias: growth performance in a complete diallel cross experiment with eight strains of Oreochromis niloticus
Type: Journal Article
A complete diallel cross experiment was carried out with eight strains of Nile tilapia (Oreochromis niloticus). The strains represented four wild populations collected from various locations in Africa and four populations ...
Genetic variation in lytic activities of blood serum from Nile tilapia and genetic associations with survival and body weight
Type: Journal Article
The objective of the present investigation was to determine the genetic variation in lysozyme activity and SH activity in blood serum from a family material of Nile tilapia (O. niloticus) and to study the genetic associations ...
