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: Genetic parameters for body weight at harvest in Nile tilapia (Oreochromis niloticus) during five generations of testing in multiple environments
Type: Journal Article
The main objective of this paper was to report more reliable estimates of the genetic variation and the genotype by test environment interaction for harvest body weight in the GIFT population in the Philippines than could ...
GIFT tilapia raise culture efficiency in Sri Lanka
Type: Journal Article
The wide distribution and ongoing improvement of GIFT tilapia in Sri Lanka is raising the living standards of poor people and contributing to gender equality through employment for women in rural areas. So far, the GIFT ...
Benchmarking the environmental performance of best management practice and genetic improvements in Egyptian aquaculture using life cycle assessment
Type: Journal Article
Egyptian aquaculture is gaining importance as an affordable and nutritious source of animal protein among Egyptians. Nile tilapia dominates production (77% of total production), followed by carps (17%) and mullets (11%). ...
Analysis of RAPD polymorphisms in Rastrelliger kanagurta off India
Type: Journal Article
Analysis of RAPD loci in Indian mackerel (Rastrelliger kanagurta), as generated by the arbitrary primer OPA 07 (GAAACGGGTG), revealed a maximum within-region genetic variability for samples from the east coast of India. ...
Selective breeding for increased body weight in a synthetic breed of Egytian Nile tilapia, Oreochromis niloticus: response to selection and genetic parameters
Type: Journal Article
Selection for harvest weight was performed in a fully pedigreed synthetic line of Nile tilapia (Oreochromis niloticus) in Egypt for two generations. Records were available over three spawning seasons (2002, 2003 and 2004) ...
Production priorities overshadow genetic quality at African fish hatcheries
Type: Journal Article
Based largely on FAO programs that address rural poverty, small-scale hatcheries have been developed in Africa to produce catfish and tilapia fingerlings. Production practices that fail to maintain genetic diversity, ...
Assessment of the impact of dissemination of genetically improved Abbassa Nile tilapia strain (GIANT-G9) versus commercial strains in some Egyptian governorates
Type: Journal Article
WorldFish initiated a selective breeding program in Abbassa--Egypt to develop and produce the genetically improved Nile tilapia strain known as “Genetically Improved Abbassa Nile tilapia (GIANT)”, adopting the same technology ...
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. ...
Genetics of flesh quality in fish
Type: Journal Article
Genetic improvement has led to substantial increase in productivity in farmed animals and in tropical fin fish, this is evident in tilapia. The GIFT (Genetically Improved Farmed Tilapia) strain of Nile tilapia (Oreochromis ...
