Process conditions for successful low-cost extrusion of floating fish feed granules for African catfish, Clarias gariepinus in West Africa
The production of floating fish feed for the African catfish, Clarias gariepinus, in sub-Saharan African countries is challenged by a lack of affordable equipment and processing know-how. The present study aimed at defining the operating conditions for a locally built single-screw extruder. The effects of main ingredients and their particle size on the extrusion outcome were assessed. Moisture contents of 200 to 250 g...
