Bio-economic evaluation of African Catfish (Clarias gariepinus) interaction with Nile Tilapia (Oreochromis niloticus) in low input system and its effect on water quality

Abstract

This study aims to determine the best stocking rate of African catfish (Clarias gariepinus) as a predator to control unwanted tilapia recruits in a bilyculture system and to assess the effects of that on fish growth, water quality, total fish production, and economic returns under low input production system in earthen ponds
