Development of fish feeds for African catfish (Clarias gariepinus Burchell 1822) farming in Sierra Leone, West Africa
This preliminary study was carried out to formulate high quality least-cost feed for the farming of African catfish (Clarias gariepinus Burchell 1822) in Sierra Leone. Locally sourced feed ingredients with vitamin premixes, lysine and methionine were used to formulate a 45% crude protein feeds for the African catfish. Proximate contents determined for the practical feed were compared with two imported commercially...
Assessing the impact of a budget cage technology on Nile Tilapia (Oreochromis niloticus) production in the Bontanga, Golinga and Libga reservoirs in Northern Ghana, Africa
The potential of irrigation reservoirs in northern Ghana to support Nile Tilapia (Oreochromis niloticus) production in 1 m3 budget cages was assessed over six-months in three reservoirs (Bontanga, Golinga and Libga). Fingerlings with a mean weight of 17.0 ± 5.0 g were randomly stocked at 50, 100, 150, 200 and 250 fish per cage in duplicate and fed with a commercial tilapia feed (Raanan, 30% protein level) at 3 to...
