dc.description.abstractThis study was conducted to assess the effect of polyculture on tilapia {Oreochromis niloticus) growth and to evaluate African Catfish (Clarias gariepinus) as a predator control for unwanted tilapia offspring in a poly culture system. Three treatments were tested using three l00m2 concrete. tanks. Ponds were stocked with male tilapia in treatment (T1), mixed sex tilapia in treatment {r2) and mixed sex tilapia with catfish in treatment {TJ). This treatment (T3) is stocked at the ratio 5: 1, while treatment (T1) and (T2) is a control treatment. Fish were feds with a commercial diet ration 1.5% of body weight per day. Feed inputs is adjusted biweekly, were based on tilapia biomass. Water quality parameters were estimated bi,veekly. AT-test was used to compare the weight gain of tilapia and net fish yield. Weight gain and net fish yield were significantly higher in treatment (T1), while treatment (T3) also have a high Weight Gain (WG) and Net Fish Yield {NFY) than treàtment (T2) which have a very low weight gain WG and net fish yield NFYen
