Analysis of research for the development of tilapia farming: an interdisciplinary approach is lacking
Type: Journal Article
Tilapias, particularly Oreochromis spp., are farmed throughout the tropics and subtropics but most of the production comes from a few Asian countries. Global production increased by about 13%/yr from 1985 to 1989. A global ...
Tilapia, Sarotherodon or Oreochromis?
Type: Journal Article
The debate on the scientific nomenclature for tilapias is likely to intensify with the publication this year by the British Museum of Natural History of Dr. Ethelwynn Trewavas' long-awaited mono¬graph "A review of the ...
The Genetic Improvement of Farmed Tilapias (GIFT) project: the story so far
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 ...
Introgressive hybridization in cultured tilapia stocks in the Philippines
Type: Journal Article
The importance of conservation of tilapia genetic resources, the need to ascertain the identity of farmed and experimental populations, the provision of single species and hybrid seed for culturists and future approaches ...
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 ...
Research directions for tilapia culture
Type: Journal Article
Areas in which research is required regarding tilapia culture are indicated. The confused status of cultured stocks, a consensus on choice of species and culture methods are discussed.
Electrophoretic evidence for extensive hybrid gene introgression into commercial Oreochromis niloticus (L.) stocks in the Philippines
Type: Journal Article
The usefulness of isozyme and protein markers in identifying tilapia species and their hybrids is demonstrated Genetic characterization of Oreochromis niloticus populations from commercial farms, experimental stations, and ...
Tilapia production booms in the Philippines
Type: Journal Article
Tilapia is the second most popular cultured fish in the Philippines. Increased consumer demand is discussed briefly and an account is given of hatcheries, cage culture in lakes and land based grow-out systems. Future ...
