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.

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.

The effect of replacing fishmeal with kikuyu on digestive enzyme activities was investigated in Tilapia rendalli, Oreochromis mossambicus and Clarias gariepinus. Five diets (30% CP: 20 MJ GE kg-1 DM) were formulated. In the control diet, fishmeal was replaced at 25, 50, 75 and 100% by kikuyu leaf meal. Each diet was assigned to three groups of 20 fish (per species). Fish were fed to apparent satiation three times daily for 60 days. There was a significant decrease (P less than 0.05) in protease, amylase and lipase activities at higher kikuyu inclusion. Protease activities were higher in T. rendalli followed by O. mossambicus and C. gariepinus had the lowest activities. The inability of the fish to produce enough enzymes at higher kikuyu inclusions resulted in significantly lower growth performance and poor protein digestibility. This decrease was more pronounced in C. gariepinus than the tilapias.

The effect of varying levels of Nymphaea leaf meal on the growth and survival of common carp, Cyprinus carpio was investigated. In a feeding trail of 45 days, three experimental diets containing nymphaea leaf meal at 300, 400 and 500g kg-1 level of incorporation were fed to triplicate groups of 10 fish each. The conventional feed used in India, consisting of a mixture of groundnut oil cake and rice bran in 1:1 ratio served as the control. Best growth in terms of weight gain (35.2g), specific growth rate (4.67), protein efficiency ratio (PER) (2.7), feed conversion ratio (FCR) (2.5) was obtained for the test diet with 400g kg-1 nymphaea meal inclusion level. However no statistical difference was observed between the three experimental diets. Digestive enzyme activity and digestibility studies also indicated the same pattern. Thus the results of the present study indicate that a diet of 300g kg-1 overall protein with nymphaea meal included at 400g kg-1 can elicit good growth response and survival in common carp.

The blood profile and histology of selected tissues (kidney, lungs, intestine, and epididymis) of Balami Sheep fed Shea Cake meal supplement was investigated. A total of thirty-two (32) sheep of the average weight range of 11.75-14.75kg comprising an equal number (16) of males and females were randomly allotted to four dietary treatments in a completely randomized experimental design with eight sheep per treatment for twelve weeks duration. Treatment 1 (T1) was a control diet and had zero inclusion level of Shea cake meal (SCM), while treatments 2,3, and 4 had 10%,15%, and 20%  inclusion of SCM, respectively. At the twelfth week of the experiment, two blood samples of 5ml each were taken from each animal from the jugular vein. The first set was preserved in Ethylene Diamine Tetra Acetic Acid (EDTA) bottle for haematological parameters, while the second samples were preserved without EDTA for serum examination. Representative samples of tissues were randomly selected and slaughtered for gross microscopic examination. There was a significant difference (P<0.05) at various levels of inclusion for parameters investigated. The white blood cell (WBC), Red blood cell (RBC), and Packed cell volume (PCV) recorded the highest values at T3 (15% inclusion level) (13.42 x109/L), 2.92x1012/L, 3.75%, respectively). The serum parameters were significantly(p <0.05)different among the treatments. Total protein ranges from 54.78(mg/dl) (T1) - 60.51(mg/dl) (T2), Cholesterol70.15(mg/dl) (T1) - 78.00(mg/dl) (T4). Iron ranges from 58.15(ug/dl) (T1) - 62.88(ug/dl) (T3).The histopathology of tissues (kidney, lungs, intestine, and epididymis) showed no alteration across the treatments (P= .05) in the gross microscopic examinations. No lesion was observed in the lungs, kidney, epididymis, and intestine. The results showed that shea cake meal posed no health risk to Balami sheep and as such recommended as a good supplement in the diets of the sheep.

This research investigated the growth performance of Clarias gariepinus fingerlings (mean weight 1.130.3g) fed cockroach meal (CM) as replacement for fish meal (FM). The fish were fed with three diets containing 45% crude protein; diet 1 (control 0% CM and 0% FM) diet 2 (10% FM, 0% CM), diet 3 (10% CM, 0% FM) for 56 days. The results showed significant differences (p<0.05) for the growth parameters evaluated for the treatments. Cockroach meal-based diet gave the best results in terms of mean weight gain (1.39+0.39g), food conversion ratio (2.54+0.15), specific growth rate (1.440.29%/day), protein efficiency ratio (0.87±0.20), apparent net protein utilization (16.23±7.19) and survival rate of 62%. This was followed by fish meal-based diet while the control diet gave a significantly (p<0.05) lower values. It can be concluded from the study that cockroach meal can substitute fish meal at 10% inclusion level. However, further study can be conducted for higher inclusion levels of cockroach meal in the diets of C. gariepinus. Keywords: Insect meal, protein, catfish, feed, growth.

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.

Pengba, Osteobrama belangeri (Valenciennes, 1844) is considered as one of the candidate species for diversification of aquaculture. However, only scanty information is available on its nutrient requirements. Hence, the present study was conducted on growth and digestive enzyme activities of pengba fry in response to different dietary protein levels. Six semi-purified isocaloric diets were formulated with different levels of protein at 5% increments (25, 30, 35, 40, 45 and 50%) and fed to different groups of pengba fry for a period of 60 days. Survival of fish was significantly influenced by different protein levels (p<0.05). The highest weight gain% and specific growth rate (4.17% day-1) was obtained at 45% protein level which thereafter declined. The best feed conversion ratio (1.46) was observed at 45% protein level and the highest protein efficiency ratio (2.14) was obtained at 25% protein levelwith significant difference (p<0.05). The crude protein content of fish was significantly affected by dietary protein levels (p<0.05) and highest was recorded at 45% protein diet. Moisture, ether extract and ash content did not show significant (p>0.05) variation among dietary treatments. The activity of proteolytic enzymes (proteases, typsin and chymotrypsin) and acid phosphatase were signicantly (p<0.05) enhanced by dietary protein levels up to 45%, which were found to decline thereafter. Amylase activity was significantly decreased as protein levels increased in the diet. Lipase and alkaline phosphatase activities were not influenced by dietary protein levels. In the present study, penbga fry fed with 45% protein diet, showed the best growth performance and highest digestive enzyme activities. The activity of digestive enzymes in the gut clearly demonstrated that the proteolytic enzymes are activated in response to dietary protein utilisation and also revealed that pengba fry may require high protein (45%) diet for better growth and survival. Second order polynomial regression analysis revealed that the maximum protein requirement of pengba fry was 45.1% (r2 = 0.90). The findings of the study is expected to have significant implications for feed development for pengba aquaculture.

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.

Abstract This study was conducted to determine an appropriate replacement of fishmeal with amino acids (AAs) and optimized protein levels in practical diets for Oreochromis niloticus with mean initial body weight 12.52±0.63g. Six experimental and a control diet (total 7 diets) divided into two groups, and a control diet (D1) containing 32% protein. The first group contained three diets that included different dietary protein levels, viz. 20 (D2), 25 (D3), and 30% (D4) with AAs when replacing fishmeal by plant protein sources. In the second group, the diets were contained 20 (D5), 25 (D6), and 30% (D7) without AAs. The best growth performance was achieved in fish fed with diet D1. Total feed intake was increased with an increase in dietary protein level with AAs. The specific growth rate showed a similar pattern with a significant difference between control, D4 and D7 compared to other groups. The feed conversion ratio decreased when protein levels in the diets increased. The protein efficiency ratio showed a similar performance, with a slight increase between the control diet and diets with AAs. However, insignificant differences (P>0.05) were observed between diets with and without AAs. An economic evaluation indicated that inclusion of low fishmeal in tilapia diets reduced the price/kg of diets compared to control.

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.
