Weed control by adult and juvenile tilapia Tilapia rendalli in rainfed ponds
Type: Journal Article
Two studies were conducted in consecutive years over the time period 14 January to 1 July to determine whether labor-savings and fish growth enhancement could be achieved by stocking Tilapia rendalli directly into ponds ...
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 ...
Genetic management of aquaculture stocks in sub-Saharan Africa
Type: Report
This document is a report of a workshop on genetic resource management in sub-Saharan Africa.
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, ...
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 ...
Intensity and profitability of Clarias nursing systems in periurban Yaoundé, Cameroon
Type: Journal Article
To target development efforts, the technological options for investments in Clarias gariepinus hatchery systems were compared for cost, average weight, number of fingerlings harvested, survival and profitability in periurban ...
Towards the maximum profitability of smallholder catfish nurseries: predator defense and feeding-adapted stocking of Clarias gariepinus
Type: Journal Article
To determine how best smallholders could maximize the profitability of their catfish hatcheries, the cost/benefit analyses of using fences, hapas and bird nets to exclude predators; as well as over-stocking to create food ...
