 in the diet of Clarias gariepinus fingerlings was carried out. Freshly collected low-value tilapia was processed into tilapia fishmeal at the NIOMR fish processing plant. Feeding trial was conducted in a flow-through system. Data were generated for total weight gain (TWG), specific growth rate (SGR), feed conversion ratio (FCR), hepatosomatic index (HSI), spleensomatic index (SSI) condition factor (CF) and carcass analysis. Results obtained was not significantly different (P > 0.05) in feed conversion ratio (FCR) between fishes fed control diet (C) containing imported fishmeal based diet and fishes fed T2 diet containing whole tilapia fishmeal based diet. Feed conversion ratio (FCR) was best in fishes fed T2 diet. However, no significant difference (P > 0.05) was observed in their growth performance. Hepatosomatic index and spleensomatic index values obtained for fishes fed control diet (C) and fishes fed T2 diet were 1.008, 1.025 and 0.108, 0.178 respectively. Condition factor of fishes fed control diet C, and T2 were however not significantly different (p > 0.05). Carcass composition analysis revealed that there was no significant difference in the crude protein contents of fishes fed with control diet (C) and low value tilapia based diet. It can be concluded that value addition of stunted tilapia (low-value tilapia LVT) as fishmeal has a great potential of replacing imported fishmeal in the aqua feed industry.&picture=http://www.aascit.org/aascit/decorators/img/journal/907.jpg)

Absolute replacement of imported fishmeal with stunted tilapia fishmeal (Low-Value Tilapia LVT) in the diet of Clarias gariepinus fingerlings was carried out. Freshly collected low-value tilapia was processed into tilapia fishmeal at the NIOMR fish processing plant. Feeding trial was conducted in a flow-through system. Data were generated for total weight gain (TWG), specific growth rate (SGR), feed conversion ratio (FCR), hepatosomatic index (HSI), spleensomatic index (SSI) condition factor (CF) and carcass analysis. Results obtained was not significantly different (P > 0.05) in feed conversion ratio (FCR) between fishes fed control diet (C) containing imported fishmeal based diet and fishes fed T2 diet containing whole tilapia fishmeal based diet. Feed conversion ratio (FCR) was best in fishes fed T2 diet. However, no significant difference (P > 0.05) was observed in their growth performance. Hepatosomatic index and spleensomatic index values obtained for fishes fed control diet (C) and fishes fed T2 diet were 1.008, 1.025 and 0.108, 0.178 respectively. Condition factor of fishes fed control diet C, and T2 were however not significantly different (p > 0.05). Carcass composition analysis revealed that there was no significant difference in the crude protein contents of fishes fed with control diet (C) and low value tilapia based diet. It can be concluded that value addition of stunted tilapia (low-value tilapia LVT) as fishmeal has a great potential of replacing imported fishmeal in the aqua feed industry.
