A feeding trial was conducted to determine the effect of biscuit waste meal on the growth performance and utilization of Clarias gariepinus juveniles. A total of 300 juveniles of average weight 8.85g were randomly divided into five Treatments, each Treatment had three replicates. Twenty juveniles were distributed into each happa (0.7m3). The happa were suspended to ¾ of their volume using kuralon ropes carefully tied round the bamboo poles across the concrete tanks. Five diets containing 40% crude protein were formulated in which maize was replaced with biscuit waste meal at treatment; Diet 1 (TD1) 0%, 25% (TD2), 50% (TD3), 75% (TD4), 100% (TD5) levels. The fish were fed at 3% body weight per day for 10weeks. The results showed that biscuit waste was most suitable as an energy supplement when incorporated at 25% replacement (TD2) with maize. TD1 had the highest weight gain followed by TD2, TD3, TD4 and TD5 respectively. There were no significant differences (P>0.05) in the growth response in TD1 (0%), TD2 (25%) and TD3 (50%). It is therefore concluded that biscuit waste meal is a cheap source of non conventional energy source which can be used favorably to replace maize (25% inclusion level) as an energy source in the diets of C. gariepinus.

Immuno-nutrition studies have shown that some nutrients are linked to the immunological status of fish. Growth performance, nutrient utilization and intestinal microflora were examined in Clarias gariepinus. The 120 C. gariepimus fingerlings (weight, 2.33±0.07g)were fed Aloe barbadensis leaves-paste supplemented diets in 40L freshwater-filled plastic tanks ad libitum twice daily for 12 weeks. The experimental diets containing 40% crude protein were supplemented with three concentration of A. barbadensis leaves-paste: ABL1-1%; ABL2-2%; ABL3-3% and control-0%. Mean weight gain (MWG) and percentage weight gain (PWG) increased (p<0.05) as the concentration of A. barbadensis increased. MWG (17.95±0.78) and PWG (772.2±54.94) were highest in fish fed ABL3 and lowest MWG (11.92±1.16) and PWG (17.95±0.78) in fish fed control diet. Nutrients were better utilized among the diets supplemented group at different significant levels (p < 0.05). The highest value of ANPU was observed in ABL1 when compared to all other treatments including the control. Survival rate decreased as concentration of paste increased. There were no significant differences (p>0.05) in the total bacterial counts (TBC) in A. barbadensis leaves-paste supplemented diets and the control having the highest TBC (23.67 ±0.88 x 105 CFU/ml). Growth of total fungal counts (TFC) was not observed in ABLI. There was a reduction in TFC as the concentration increased in the other supplemented diets, and the control having the highest TFC (7.67 ± 0.44 x 105CFU/ml). The study concluded that inclusion of 1% A. barbadensis leaves-paste as supplement in the diet could effectively improve the growth performance, nutrient utilization and survival of cultured C. gariepinus. A. barbadensis leaves-paste could also reduce the microbial load of the fish.

The effects of replacing soybean meal with graded levels of fermented Senna obtusifolia seed meals (SOSM) on the growth performance of Clarias gariepinus were investigated. Five isonitrogenous (42% crude protein) and isocaloric (25.7% NFE) diets were formulated in which fermented replaced soybean meal (SBM) at 0% (SOSM0), 25% (SOSM25), 50% (SOSM50), 75% (SOSM75) and 100% (SOSM100) inclusion levels and a commercial feed (CmF) as the second control. Three hundred and sixty (360) fingerlings of (Clarias gariepinus) mean weight (2.85±0.01g) were stocked at (20) fish per tank volume in triplicate groups per treatment and fed 3% body weight twice a day of the experimental diets for 180 days. The feeding rate was adjusted after weighing. The water qualities were within range recommended for Clarias gariepinus. There were no significant differences (p> 0.05) in growth performance and nutrient utilization between the control groups and those fed the fermented SOSM diets at 25%. The commercial, 0% and 25% groups had the highest mean weight gain (279 to 280 g), significantly (P<0.05) superior to the groups that received the, 50%, 75% while the group that received 100% SOSM diet had the poorest mean weight gain (132.72g). Feed conversion ratios (FCR) of all treatments ranged from (1.75 to 2.18). These values increased slightly by increasing levels of fermented SOSM from 50 to 100%. The best FCR, 1.75± 0.02, recorded for fish fed 25% fermented SOSM indicated a superior level of utilization of the SOSM diet by the fish. There was no significant difference (P>0.05) in the protein intake among the group of fish fed 0 and 25%, but significant difference (P<0.05) occur in fish fed 50, 75 and 100% fermented SOSM respectively. Protein efficiency ratio (PER) exhibited significant differences (P<0.05) in all treatments except in the control diets that were not statistically different (P>0.05) from the fish fed the 25% fermented SOSM. The PER values increased among the experimental fish with respect to the quantity of total feed intake. There were no significant differences (P>0.05) in apparent net protein utilization (ANPU) among treatments CmF, 0% and 25%. The ANPU was highest in fish fed 0% fermented SOSM (91.6±0.04) while fish fed 75 and 100 % fermented SOSM in diets were 71.4±0.02 and 73.4±0.03 were the least. There was a significant (P<0.05) difference in the effect of the inclusion levels of fermented (SOSM) on final body carcass composition among treatments. This study showed that soybean meal can be substituted with fermented Senna obtusifolia seed meal up to 25% level in Clarias gariepinus diets without any negative effects on the growth and feed efficiency.

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.

Protein Diets

One hundred and twenty Clarias gariepinus fingerlings (2.33 ± 0.07 g) were fed with 40% crude protein diets containing three concentrations of Aloe barbadensis leaves-paste: ABL1, 1%; ABL2, 2%; ABL3, 3%, and control, 0% ad libitum twice daily for 12 weeks. Mean weight gain and percentage weight gain increased (P < 0.05) as concentration of A. barbadensis increased. Survival rate decreased as concentration of paste increased. Differences (P < 0.05) seen in packed cell volume (PCV), haemoglobin (Hb), and red blood cell (RBC), thus highest in ABL3: PCV (36.67 ± 0.89%), Hb (12.37 ± 0.37 g dl–1) and RBC (3.47 ± 0.08×106 L–1) and lowest in control: PCV (22.0 ± 0.58%), Hb (7.37 ± 0.20 g dl–1) and RBC (2.07 ± 0.06 ×106 L–1). Liver histology of control fish was normal, while fatty degenerations were seen in the treated fish. The histology of fish kidney was normal in all treatments. The study concluded that 1% A. barbadensis leaves-paste could effectively improve growth performance, nutrient utilization and survival of cultured C. gariepinus.
