Producing tilapia in small cage in West Africa
Type: Manual
This document is part of a series of 5 technical manuals produced by the Challenge Program Project CP34 “Improved fisheries productivity and management in tropical reservoirs”. The Water Research Institute (WRI) in Akosombo, ...
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 ...
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) ...

In this review, the author provides an overview of the small water bodies as an important inland fishery resource and analyses the global trends in their utilization. He also assesses the opportunities for enhancing fish ...
Enhancing the productivity of small waterbodies
Type: Journal Article
Most small waterbodies were built for irrigation and/or drinking water storage for humans and livestock, but have also been shown to play an important role in watershed management. Apart from natural lakes, small waterbodies ...
Relative Importance of Various Predators in Clarias gariepinus Fry Mortality in Cameroon
Type: Journal Article
To estimate the relative importance of the most common predators of Clarias gariepinus fry, increasing levels of protection were afforded to exclude amphibians, aquatic arthropods and birds. At a stocking density of 10 ...
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 ...
