Type: Journal Article
This issue of Naga features three articles about a project on the Genetic Improvement of Farmed Tilapias (GIFT) and a related article on the trend to genetic deterioration in some carp hatcheries. The first is on the genesis ...
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 ...
Biochemical and morphometric approaches to characterize farmed tilapias
Type: Journal Article
Biochemical (electrophoresis and mitochondrial DNA) and morphological analysis are important tools for the characterization of strains. Reference is made to studies conducted in the framework of the Genetic Improvement of ...
Population control in farmed tilapias
Type: Journal Article
Under the majority of culture practices, the reduction or elimination of reproduction in culture ponds results in significantly improved yields of marketable fish. An examination is made of existing methods for the control ...
Preference of different terrestrial plants as food for Tilapia rendallli and Oreochromis shiranus
Type: Journal Article
Fish have distinct preferences for plants and there is need to identify those that will lead to good growth and production, especially in Africa where there is abundant natural and agricultural waste vegetation. Some plants ...
Photographic image analysis for morphometric studies of tilapia
Type: Journal Article
Biologists have long employed morphometry as a tool in identification, grouping of populations and stock identification of fish. For tilapias, studies have been made on the variability of morphomeric characters in Egyptian ...

On improving the resolution of the recruitment patterns of fishes
Type: Journal Article
It is proposed that the "recruitment pattern" routine of the ELEFAN II program can be modified to allow, in addition to length-frequency data, the use of "restructured" data files. An example, based on Oreochromis niloticus ...
Growth and feed utilization of Oreochromis niloticus fingerlings fed with diets containing cassava peelings and mango seeds
Type: Journal Article
The results are presented of trials conducted whereby cassava peel and mango seed were fed to Nile tilapia (Oreochromis niloticus ) fingerlings. Findings indicate that these products may successfully be used as part of thediets ...
