Abstract

The use of Nymphaea lotus as energy replacement in the diet of Clarias gariepinus fingerlings was investigated in a 12-week experiment. Five isonitrogeneous (40% crude protein) diet were formulated using dried Nymphaea lotus leaves at 0% (T1), 12.5% (T2), 25% (T3), 37.5% (T4) and 50% (T5) inclusion levels as partial substitutes for maize meal, with three replicates each. Growth and nutrient utilization, Haematological and serum biochemistry parameters were determined and the data were subjected to one-way analysis of variance. The results showed that fish fed with T1 recorded the highest mean weight gain (26.58±3.00g), which was not significantly (p>0.05) different from those of the other dietary treatments. The least growth indices were recorded in fish fed T5 (50%). There was no significant difference (p>0.05) among the values of Heterophil (HET), lymphocyte (LYM), and mean corpuscular haemoglobin concentration (MCHC) among the treatments. The serum biochemistry analysis showed that the highest value (14.10±1.83) of Total protein (TP) was observed in T5 which was not significantly different (p>0.05) from other treatment while the lowest value (9.70±0.60) of TP was observed in T2. The highest value (63.70±3.60) of Aspartate aminotransferase (AST), was recorded in T5 while the least value (30.30±1.50) was observed in T1. It can be concluded that dried N. lotus can only replace maize at 25% inclusion level in the diet of C. gariepinus.
