Type: Journal Article
Fish provides 15% of the total animal protein in human diets. It is also the primary source of livelihood for 35 million people (30 M in Asia and 2.6 M in Africa). The increase in global population and demand for fish ...
Perspectives from Agriculture: Advances in livestock breeding-Implications for aquaculture genetics
Type: Journal Article
In this paper we present livestock breeding developments that could be taken into consideration in the genetic improvement of farmed aquaculture species, especially in freshwater fish. Firstly, the current breeding objective ...
Investing in Africa: the WorldFish Center's African strategy in summary
Type: Journal Article
Across much of Africa, freshwater and coastal fisheries provide an important source of food and livelihood for many millions of people. In addition, the aquaculture potential of the continent has only recently begun to be ...
Characterization of some bacteria isolated from Oreochromis niloticus and their potential use as probiotics
Type: Journal Article
A total of one thousand Oreochromis niloticus held in earthen ponds of the WorldFish Center were used in this study. Forty of these were randomly collected from the ponds and subjected to bacteriological and pathological ...
Comparison of some traits of economic importance in tilapias (Orechromis niloticus and Sarotherodon galilaeus) with particular reference to their culture in Ghana
Type: Journal Article
This study was conducted to determine which of the two major tilapia species in freshwater capture fisheries in Ghana, Oreochromis niloticus or Sarotherodon galilaeus, is more suitable for breed improvement and pond culture. ...
