Investment Appraisal of Genetic Improvement Programs in Nile tilapia (Oreochromis Niloticus)
Type: Journal Article
The economic benefit derived from a genetic improvement program with Nile tilapia (Oreochromis niloticus) was examined from a national perspective. An industry structure was assumed whereby the genetic improvement program ...
On-farm and on-station comparison of wild and domesticated Cameroonian populations of Oreochromis niloticus
Type: Journal Article
Wild (Sanaga River) and domesticated populations of Oreochromis niloticus were compared onfarm and on-station in the Central Province of Cameroon to determine the degree to which genetic deterioration of stocks may have ...
Can sexual dimorphism and body shape be altered in Nile tilapia (Oreochromis niloticus) by genetic means?
Type: Journal Article
The objective of this study was to estimate genetic parameters in GIFT (Genetically Improved Farmed Tilapia), especially focusing on the genetic correlation between trait expressions in both sexes and among measurements ...
Mating systems and male reproductive success in Nile tilapia (Oreochromis niloticus): a microsatelite analysis
Type: Journal Article
Fry production in Nile tilapia, Oreochromis niloticus is typically achieved by mass spawning of males and females stocked in large hapas suspended in ponds. In such spawning aggregations, territorial behavior and reproductive ...
Genetic improvement of farmed tilapias: composition and genetic parameters of a synthetic base population of Oreochromis niloticus for selective breeding
Type: Journal Article
The present study is based on data recorded from fish of the third generation of the GIFT project (Genetic Improvement of Farmed Tilapias). The objective of the study was to compose a synthetic base population of Nile ...
Heritability estimates and response to selection for growth of Nile tilapia (Oreochromis niloticus) in low-input earthen ponds
Type: Journal Article
This study presents results of two generations of selection (G1 and G2) for growth of Nile tilapia. The selection environment consisted of earthen ponds which were fertilized daily with 50 kg dry matter (dm)/ha chicken ...
Potential of genetics for aquaculture development in Africa
Type: Journal Article
Aquaculture in Africa is fairly insignificant by world standards and accounts for a mere 0.4 per cent of global aquaculture production. The application of genetics can play an important role in efforts to increase aquaculture ...
Performances of Nile Tilapia (Oreochromis niloticus) selected for high growth rate after three generations
Type: Journal Article
A selective breeding study for live weight based on a fully pedigreed population of GIFT (Genetically Improved Farmed Tilapia) strain was carried out at the Aquaculture Extension Centre, Department of Fisheries, Jitra, ...
Pawpaw seed as fertility control agent on male Nile tilapia
Type: Journal Article
To find out if pawpaw (Carica papaya) seeds can induce sterility in male Nile tilapia (Oreochromis niloticus) and to determine if sterility so induced is reversible or otherwise, mature male tilapia of mean weight 40 g ...
