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 ...
Performance and nature of genetically improved farmed tilapia: a bioeconomic analysis
Type: Journal Article
The International Center for Living Aquatic Resources Management (ICLARM), in collaboration with its partner organizations, has developed an improved strain of Nile tilapia (known as the GIFT strain) which shows superior ...
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 ...

Current trends in the Asian tilapia industry and the significance of genetically improved tilapia breeds
Type: Book Chapter
Tilapia production is increasing rapidly in Asia, and is one of the most popular aquaculture activities in PR China, Philippines, Indonesia, Taiwan and Thailand. The most popular farmed tilapia species is still the Nile ...
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 ...
Multiple haemoglobins in three tilapiine species of the genus Oreochromis and in eight strains of O. niloticus
Type: Journal Article
Among three tilapiine species, Oreochromis aureus (Steindachner), O. mossambicus (Peters) and O. niloticus (L.), fifteen banding positions of haemoglobin were resolved using citric acid-aminopropylmorpholine pH 7.0 buffer. ...
