This study assessed the effects of microalga Phaeodactylum tricornutum supplement on the gustation, stomach histology, growth performance and nutrient utilization of Clarias gariepinus juveniles. One hundred and fifty (150) C. gariepinus juveniles of mean weight 20.05±0.05g were distributed into 15 plastic tanks (40×30×35) cm3. Five graded levels (0.00 (control), 0.50, 1.00, 1.50, and 2.00g/100g of P. tricornutum supplements were included in the diets of C. gariepinus denoted as Control, PT1, PT2, PT4 and PT5, respectively. Fish were fed for 56 days at 5% body weight. Results at the end of the experiments showed that the highest body weight was recorded in fish fed 1.5g/100g P. tricornutum diets. The best feed conversion ratio, specific growth rate, protein efficiency ratio and percentage survival was found in PT3. There was significant difference (p<0.05) in the feed intake of fish with PT4 having the highest feed intake. The stomach histology revealed increase in the gustation cells in the stomach of experimental fish with increasing levels of P. tricornutum supplementation. This study showed that the inclusion of P. tricornutum supplement at 1.5g/100g level in the diet of C. gariepinus juveniles improved the gustation, growth performance and nutrient utilization of C. gariepinus.

Effect Of Feeding

This study was conducted to examine the effect of feeding at different time intervals of the day on the growth efficiency of African catfish (Clarias gariepinus, Burchell 1822). Juveniles of African catfish Clarias gariepinus with an average weight of 16.0±0.20g were randomly stocked into four treatment groups (T1, T2, T3 and T4) at 10 fish per group using a completely randomized design (CRD). The treatment groups were T1 (Fish fed once daily), T2 (Fish fed twice), T3 (Fish fed Thrice daily) and T4 (Fish fed four times daily). They were all fed 3% of their body weight. Data obtained was analysed using Genstat package while means where separated using Duncan Multiple Range Test. The result of the study showed that the highest weight gains of 104.49g was recorded in Treatment 3, this was followed by Treatment 2 with a mean weight gain value of 92.42g. The least value of weight gain (76.74g) was recorded in Treatment 1. Also, the highest feed intake value of 142.83g was recorded in Treatment 3, this was followed by Treatment 2 with a mean feed intake value of 135.12g. The least value of feed intake (112.95g) was recorded in Treatment 1. The feed conversion ratio and Protein Efficiency ratio (PER) also followed similar trend as that of weight gain and feed intake. The highest PER value of 2.10 was recorded in Treatment 3, this was followed by Treatment 2 with a mean PER value of 1.69. The least PER value (1.39) was recorded in Treatment 4. ANOVA showed that there was significance difference (P<0.05) in the PER value between Treatment 1, 2 and 3. However, Treatment 1 was not significantly different (P>0.05) from Treatment 4. At the end of the Study, three times feeding per day was found to be sufficient for maximum growth as it recorded the highest value for growth parameters monitored and was significantly different from other treatments.
