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.

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.

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.

Background The objective of the present study was to evaluate the growth performance and feed utilization of African catfish Clarias gariepinus fed a commercial diet and reared in the biofloc system enhanced with probiotic. Methods The treatment was the frequency of probiotic application into the cultured system, namely, 5-day interval, 10-day interval, and 15-day interval for 60 days of experiment. Biofloc culture was grown in an experiment tank (vol. 2000 L) by mixing the probiotic (Bacillus sp.) 10 mL and molasses 200 mL per liter of water.  The fish was stocked into the biofloc system 7 days after cultured at stocking density of 1000 fish tank-1.  The fish was fed a commercial diet that contains 38% crude protein, twice a day at satiation. The application of probiotic was reperformed after 5 days, 10 days, and 15 days after stocking. Results The study showed that the growth performance, survival, and feed utilization of African catfish were higher in the treatment at 5-day intervals over 60 days. The ANOVA test showed that the application frequency of probiotic into biofloc system of cultured media had the significant effect on the growth performance, survival rate, and feed utilization of African catfish. Conclusion The best growth performance and feed utilization were  found at the application of probiotic into biofloc system at 5-day intervals over 60 days.

A 56-day feeding trial was performed to examine the effects of using Nymphaea lotus leaf meal (NLM) on growth performance, feed utilization, body composition, and survival rate of African catfish (Heterobranchus longifilis). Five treatment groups in triplicates with an average of the initial weight of 0.26±0.07g were fed diets incorporated with graded levels of NLM (0, 10, 20, 30 and 40%). The obtained results showed that higher final body weight (FBW), daily weight gain (DWG), and specific growth rate (SGR) were observed with fish fed the control diet (CD) and NLM at the level of 20% compared to those of fish fed other diets. Protein efficiency ratios (PER) were not altered with dietary treatment. In addition, feed conversion ratio (FCR) of fish groups fed up to 30% of NLM were not varied (p>0.05), meanwhile, daily feed intake of fish fed NLM diets exhibited lower values compared to those of fish fed CD. Final whole body proximate compositions of catfish showed no significant differences (P>0.05) except for the body total fat and ash contents. Fat contents of fish fed diets incorporated with NLM were significantly lower than those of fish fed the control diet (CD) (P<0.05). Meanwhile, ash contents of fish fed diets incorporated with high levels of NLM (30, 40%) were significantly lower than those of fish fed the control diet (CD) (P<0.05). Survival rates ranged between 72 - 80% and there were no differences among all groups (P > 0.05). Therefore, the results of the present study suggest that up to 20% of NLM protein can be incorporated in the diet of African catfish with no adverse effects on growth performance, feed utilization, and survival rate.

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.

A feeding trial was conducted to examine the dietary effects of using African Palm weevil in the diet of Catfish. Five experimental diets containing 40% crude protein were formulated, four of these diets contained defatted African palm weevil larvae meal at varying inclusion levels denoted as APW25%, APW50%, APW75% and APW100% while the diet with fish meal (APW0%) served as control diet. The experiment was conducted in triplicates for 10 weeks using 15 aquaria glass tanks with 10 fish per tank. The percentage weight gain was significantly different (P>0.05) across the fish fed experimental diets, with the highest percentage weight gain (1118.30g) recorded in fish fed diet APW100 and the lowest percentage weight gain (749.40g) recorded in fish fed diet FM. The feed conversion ratio (FCR) were not significantly different (P<0.05) across the experimental diet. The highest FCR value (1.48±0.42) was recorded in the fish fed diet FM while the lowest FCR value (1.06±0.01) was recorded in fish fed diet APW100. There were no significant differences (P>0.05) in the PER among the experimental diets. It could be concluded that defatted African palm weevil larvae meal in the diet in replacement of fishmeal.in the diet Clarias gariepinus juvenile.

This work was conducted to study the effect of diets supplemented with different levels of aqueous extract of siamweed (Chromolaena odorata) leaf powder on growth performance, feed utilization and some blood parameters of African catfish (Clarias gariepinus) fingerlings in 2014 at the Federal University of Technology, Nigeria. Fingerlings of about 6.84-6.86 g were fed diets supplemented with four concentrations (0.5, 1.0, 1.5 and 2.0 g) of C. odorata leaf extract powder for eight weeks. The highest specific growth rate (0.96±1.16 % day–1) and best food conversion ratio (2.87±0.26) were obtained in fish fed 0.5 g 100 g−1 C. odorata leaf extract powder diet treatment. There were significant differences in fish carcass protein, lipid or ash content among the treatments (p<0.05). No differences occurred in white blood cells among the treatments (p>0.05) but there were greater improvement in the white blood cells of fish fed on dietary C. odorata leaf extract powder compared to the fish fed the control diet. The results suggest that dietary supplementation with C. odorata leaf extract powder improved growth rate, feed utilization, white blood cells and survival of C. gariepinus fingerlings.

A fifty-six (56) day experiment was conducted to evaluate the growth performance and feed utilization in Clarias gariepinus fingerlings fed with six iso-nitrogenous diets in which oven-dried melon (Citrillus lanatus) seed peel meal (MSPM) was substituted for yellow maize at 0, 20, 40, 60, 80 and 100% inclusion levels. A total of 270 fingerlings of C. gariepinus (mean weight: 7.40 ± 0.02 g) were randomly allocated into eighteen plastic bowls (50-litre capacity) at 15 fish per bowl and fed the control and experimental diets twice daily at 5% of their body weight. Proximate composition of melon seed peel meal-supplemented diets and fish carcass was determined using standard procedures. Results showed that crude protein was highest (60.75%) in fish fed diet 2 (20% MSPMsupplemented diet) and least (58.21%) in fish fed diet 4 (60% MSPM-supplemented diet). Fish fed diet 2 (20%MSPM-supplemented diet) had statistically (p < 0.05) superior values of MWG (48.27 g), SGR (1.56%/day) and FCR (0.48) beyond which growth and feed utilization indices gradually declined with increased level of MSPM inclusion. This study demonstrated that 20% substitution level of oven-dried melon seed peel meal produced the best growth and feed utilization in C. gariepinus.

On the bulls of red steppe breed with duodenal and ileocecal cannulas when feeding iso-enery and isoprotein diets with different amounts of soluble protein (SP) and degradable protein (DP) studied conversions of dry matter (DМ), organic matter (OM) and crude protein (CP) separately in the complex stomach, small (SI) and large (LI) parts of the intestine. Evaluated the nitrogen balance by the amount of protein absorbed into the SI, the losses of nitrogen with urine – by the proportion of urea nitrogen. The diet consisted of awnless bonfire hay, pea deer, and mineral supplements. Various amounts of SP in the diets were achieved by feeding natural pea dough (control) and roasted pea dough at a temperature of 105°C (experiment). In a compound stomach, the digestibility CP on the experimental diet with a reduced level of SP was by 10 % less. In the control diet with a high level of SP is more in SI received of ammonia nitrogen. In SI digestibility of DM and OM on the experimental diet are by 8–10 % more. Amounts of DM, OM and CP in LI on a control diet decreased by 5.6–7.5 %, in the experimental diet – not changed. On an experimental diet with an increased level of NSP, the SI received more nitrogen and was digested by 10 % more than in the control. The calculated nitrogen balance according to the classical scheme did not reflect the true amount of it assimilated in the body. On the control diet with an increased level of SP, there was the devaluation of the protein in the feeds and oblasting due to the larger release in urea by 40 % of the nitrogen in the form of urea.
