Response of two generations of selection to increased body weight in channel catfish, Ictalurus punctatus, compared to hybridization with blue catfish, I. furcatus, Males
Type: Journal Article
Two generations of selection for increased body weight in Kansas (AU-KS-2) and Marion (AU-MS-2) lines of channel catfish, Ictalurus punctatus, resulted in a 12% and 11% increase in body weight at market size, respectively. ...
Freshwater fish seed resources and supply: Africa regional synthesis
Type: Book Chapter
The availability and quality of fingerlings for stocking in aquaculture ponds have repeatedly been identified as a key constraint to the development of aquaculture in Africa. Government hatcheries have generally failed to ...
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, ...
Comparative analysis of the environmental costs of fish farming and crop production in arid areas
Type: Conference Paper
Using published data, 20 crop and 19 fish production systems were compared for efficiency of water and nutrient (nitrogen) use. In agriculture, rain-fed cassava was most efficient, followed by rain-fed beans, pivot-irrigated ...
Survival of Clarias gariepinus fry in earthern ponds: effects of composts and leaks
Type: Journal Article
To inform decisions on improving the yields of African catfish Clarias gariepinus fingerlings in earthen ponds, the hypothesis that composts and leaks were partly responsible for usually low and variable fry survivals was ...
Advanced nursing of Clarias gariepinus (Burchell, 1822) fingerlings in earthen ponds, through recycling of tilapia recruits
Type: Journal Article
In an attempt to improve the stocking size and yield of Clarias gariepinus, small fingerlings (average weight=3 g) of the type usually produced by African hatcheries were stocked together with tilapia (Oreochromis niloticus) ...
Participatory research boosts catfish egg, fry production in Cameroon
Type: Journal Article
The omnivorous African sharptooth catfish is a valuable species suitable for culture by smallholder farmers in Cameroon. A five-year research project that brought farmers together with research interests established simple, ...
Freshwater fish seed resources in Cameroon
Type: Book Chapter
The climate, land and water resources of Cameroon, combined with the high demand for fisheries products, makes this Central African country a high potential area for aquaculture. Fingerling availability and quality have ...
Impacts of aquaculture development projects in Western Cameroon
Type: Journal Article
To measure the impact of past projects on the sustained adoption and development of aquaculture, and to assess the potential for future growth, a participatory rural appraisal (PRA) based on the Research Tool for Natural ...
Use and exchange of aquatic genetic resources for food and aquaculture: clarias catfish
Type: Journal Article
There are 58 species of Clarias recognized in FishBase (as of January 2009), 33 in Africa and 25 in Asia. Aquaculture of clariids is important with 30 countries reporting a total production of over 300 000 t worth nearly ...
