A
60-day study was conducted to investigate the dietary effect of replacement of
maize with graded levels of melon shell meal (MSM) on growth performance of Clarias
gariepinus fingerling. Five isonitrogenous diets were formulated. MSM was
added to the diet to replace maize at graded levels; 0%, 25%, 50%, 75% and
100%. Total of 150 fish (3.40±0.05g) were randomly assigned to the five
treatment diets. Each treatment
contained 10 fish per tank and each treatment was triplicated in a completely
randomised design (CRD). Fish were fed twice daily at 5% body weight in equal
proportions. Results showed significant differences (P<0.05) for measured
growth parameters. Fish fed diet containing 100% MSM had the highest mean
weight gain (70.70±4.62g), specific growth rate (SGR) (5.06±0.10%), best
feed conversion ratio (FCR) (0.54±0.04%) and protein efficiency ratio (PER)
(1.68±0.11%) compared to other treatments and the control while fish fed 25% MSM
had the poorest values for MWG (39.88±4.37g), SGR (4.20±0.16), FCR
(0.60±0.02) and PER (0.95±0.11). MSM inclusion in diet of C.
gariepinus up to 100% enhanced growth.
