Brewer’s waste is one of the promising carbohydrate and protein source by-products for fish diets. A 10-wk feeding trial experiment involving 10 different diets (10 diets for Spent millet, from locally fermented drink (Burukutu) with increasing levels of brewer’s waste (40% crude protein) was carried out to evaluate the use of spent millet, from Burukutu production in Clarias gariepinus diets in place of normal Corn. Growth performance was compared against a control diet formulated to have similar composition to a typical commercial diet. 10 experimental diets replaced successively 0%, 10%, 20%, 30%, 40%, 50%, 70%, 80%, 90%, and 100% of the Corn carbohydrate with Spent millet from locally fermented drink, Burukutu.. The diets were isonitrogenous and isocaloric. A relatively good growth performance and nutrient utilization by Clarias gariepinus fed the test diets were observed. However, the results showed significant difference (p<0.05) in weight gain, SGR, FCR and RGR between treatments, with the control performing best. The result also showed that survival rate was high in all the treatment which indicate that, spent millet from burukutu production has no adverse effect on the experimented fish. Based on this research, it wasconcluded that 50% of the corn carbohydrate in a typicalcommercial diet could be replaced with spent grain (millet) from locally fermented drink (BKT) withno adverse effect on growth and feed utilization for Clarias gariepinus.

A 56 day study was carried out to evaluate effect of temperature changes on survival, growth performance and haematology of Clarias gariepinus fingerlings fed housefly maggot meal (magmeal) diet. Ninety (90) Clarias gariepinus fingerlings, (initial mean weight 4.33±0.03g) were subjected to different environmental regulated temperature conditions in three locations (laboratory, outdoor, greenhouse). The observed average temperature was 26.53±0.01°C, 26.06±0.01°C and 31.52±0.00°C for laboratory, outdoor, greenhouse, respectively. Ten fingerlings stocked per experimental tank were fed in triplicates at 5% body weight in two portions per day. It was observed that different water temperatures affected fish growth. All experimental fish in the greenhouse died after 8 days of exposure. This happened around 14.00 hrs when water temperature reached 40°C. There was no significant difference (P<0.5) in final weight, weight gain, food conversion ratio and standard growth rate among the fish reared in the laboratory (26.53°C) and outside tanks (26.06°C), respectively. The initial carcass crude protein (Cp) value was 58.97%. At the end of the experiment fish reared in the laboratory had a crude protein value of 63.97±0.06% Cp and those reared outdoor (26.06°C) had 71.28±0.00% Cp. No significant difference in values of packed cell volume; white blood cell; haemoglobin and mean corpuscular haemoglobin concentration was found between fish reared in laboratory (26.53°C) and outside (26.06°C). However, the red blood cell (RBC); mean corpuscular haemoglobin and mean corpuscular volume showed significant difference (P>0.05). The result confirms that Clarias gariepinus fingerlings reared at a mean temperature of 26°C (within the recorded optimal temperature range for good growth) performed well. Clarias gariepinus fingerlings are not able to survive when water temperature reaches to 40oC.

Zinc (Zn) is an important trace element in fish diets that is required for growth, immunity and antioxidant defense mechanisms. The current study assessed the effects of both organic and nanoparticle zinc oxide (ZnO and ZnO-NPs, respectively) on growth performance, immune response and the antimicrobial effect against Pseudomonas aeruginosa in African catfish Clarias gariepinus. Fish were fed either a control diet or diets supplemented with organic ZnO at concentrations of 20 and 30 mg kg-1 or ZnO-NPs at concentrations of 20 and 30 mg kg-1. After 60 d, a subset of the fish was injected intraperitoneally with 3 × 107 CFU ml-1 of P. aeruginosa. Results showed that body weight gain, feed conversion ratio and specific growth rates were significantly increased in ZnO-NPs20 compared to all other groups. The dietary supplementation with 20 mg kg-1 of ZnO-NPs improved the antioxidant status of fish. Moreover, IgM, lysozyme and nitric oxide showed a significant increase in the fish which received the ZnO-NPs20-supplemented diet. A significant upregulation of growth and stress-related genes was seen in the ZnO-NPs20-supplemented group compared to other groups. However, there was no significant difference in the expression of immune-related genes among ZnO-NPs20, ZnO-NPs30 and ZnO30 groups. These findings highlight the potential use of nano-ZnO for improving growth performance, antioxidant status, immunological status and antibacterial activity against P. aeruginosa in African catfish.

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.

One hundred and twenty (120) juveniles of African catfish Clarias gariepinus were obtained in May 2015 from a reputable Fish Farm in Enugu to the University Research Farm (latitude 074o North and 082o South, longitude 068o East and 076o West with annual mean temperature of 30oC). The fish were fed for 49 days from June – July 2015 with diets containing 4 different inclusion levels of phosphorus T1 [0.6% P], T2 [0.8% P], T3 [1.00% P], T4 [1.2% P] and T5 [0% P] which served as control diet, to determine optimum P requirement for fish growth at probability level of P < 0.05 between various treatments and control. Each diet was formulated to contain 40% crude protein composed of yellow maize, soybean cake, palm kernel cake and fish meal. Fish fed with graded levels of phosphorus were significantly higher (P < 0.05) than control in FW and MDWG. There was however no significant difference (P > 0.05) in FCR and PER between T1, T2, T4 and control but T3 was significantly (P < 0.05) better in FCR (0.33) than control (0.39). Similarly, T3 was significantly (P < 0.05) higher in PER than control. Fish in T3 had the best growth performance indicative that 1% P is the optimum requirement for the growth of C. gariepinus.Res.

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.

High cost of qualitative fish feed is one of problems hampering the development and profitability of fish farming and consequently leads to food insecurity in terms of food availability and accessibility. The study was conducted to determine growth parameters and carcass composition of Clarias gariepinus juveniles of mean weight 21.74g+0.54g fed with varying levels of dietary inclusion of Clitoria ternatea seed meal substituted for soybean meal over a period of eight weeks. Four iso-nitrogenous experimental diets were formulated at 0% (control), 25%, 50% and 100% inclusion levels of C. ternatea seed meal. The 8-week feeding experiment was conducted in rectangular plastic tanks, each treatment having three replicates with two feeding regime at 5% body weight and weighed every week. At the end of the intensive feeding period, samples from each treatment were oven dried for nutritive analysis of the fish carcass. The values of mean weight gain for diets I and III were 27.7+1.11 and 27.23+0.94 respectively. Comparatively, the growth parameters values; FI(g), SGR(%), FCR(g), PER(%) and NPU(%) for control diet and diet III were the best with no significant difference (p>0.05). The Carcass evaluation revealed that Diet I had the highest crude protein which was not significantly different (p>0.05) from diet III. It was established that fish fed 50% inclusion level of C. ternatea seed meal had effective comparable biological values with the control diet in terms of growth performance and feed utilization. The total fish production (kg) showed no significant difference (p>0.05) between diets I and III.

The nutrient utilization and digestibility of blood meal-bovine rumen digesta blend diet (BMBRD) fed to Clarias gariepinus burchell (1822) was assessed using 60 C. gariepinus juveniles with a view to confirming the digestibility and suitability of the BMBRD blend inclusion level in the diet of C. gariepinus for sustainable clariid production. Two set of three iso-nitrogenous experimental diets containing 35% crude protein were formulated with 0%, 25% and 50% BMBRD inclusion level to substitute the fishmeal component which was the primary protein source. The first set of experimental diet was designed to monitor the growth performance and feed utilization was fed fortnightly in duplicate to C. gariepinus juveniles, stocked in glass aquaria (60 cm x 30 cm x 30 cm) at 4% of the body weight in two instalments daily for 10 weeks, while the second experimental diet with 0.5% chromic oxide (Cr2O3) inclusion (as a digestibility marker) was prepared and fed to the fish for 7 days to determine to digestibility of the different BMBRD included diets. The obtained results showed that the fish fed 25% BMBRD included diet had significantly higher (p < 0.05) growth performance and feed utilization indices than the other experimental diets. Similar to observation in the growth performance and feed utilization indices, the fish fed BMBRD included diets had significantly higher (p < 0.05) protein and energy digestibilities than the fish fed 0% BMBRD (control diet) and the study confirmed that fishmeal can be partially replaced up to 25% BMBRD blend in C. gariepinus diet for optimum growth performance and feed utilization.

Digestive Enzyme Activities

The study examined the growth performance, hematological and digestive enzymes of Clarias gariepinus juveniles fed Cirina forda meal (CFM) based diets in the laboratory for a period of 10weeks. Five iso-nitrogenous (30%) experimental diets were formulated at various levels of CFM inclusion levels of 0% (control), 10%, 20%, 30%, 40% and 50%, designated as diets Q, A10, B20, C30, D40 and E50 respectively. Fish fed the CFM based diets showed mean weight gain (MWG), specific growth rate (SGR) and protein efficiency ratio (PER) comparable to the control diet. There was significant differences in the digestive enzyme activities of the fish as the CFM level in the experimental diets increased. Protease and maltase activities significantly increased, with diet C30 recording the highest maltase activity (4.37) while the cellulase and glucanase activities of the fish significantly (P<0.05) reduced. There was no significant difference (P>0.05) between the PCV and RBC of the blood of the fish fed the various diets. Highest RBC (2.75 x106/µL) was obtained in fish fed the control diet while the lowest (2.55 x106/µL) was recorded in the fish fed diet E50. The White Blood Cell count and the Neutrophils of the fish fed the trial diets were not significantly higher (P>0.05) than those of the fish fed the control diets. From the results of this experiment, it is concluded that up to 50% inclusion level of Cirina forda meal in the diet of Clarias gariepinus was tolerable for good growth and physiological well-being of the fish.
