This research aimed to evaluate the health status, growth performance, and meat quality of African catfish Clariasgariepinus maintained in biofloc and nonbiofloc systems. This study applied 3 treatments with 4 replications, i.e.K500 (control, a non-biofloc system at a fish stocking density of 500/m3), BF500 (biofloc system at a fish stockingdensity of 500/m3), and BF700 (biofloc system at a fish stocking density of 700 /m3). The initial body length andbodyweight of the fish used in this experiment were 10–12 cm and 10–12g, respectively. Feeding was done byusing a commercial feed containing 29.76% protein content. The results showed that fish survival in treatmentsBF500 and BF700 were significantly different (P<0.05) from the control. The growth rate of African catfish in thecontrol (K) was the lowest (3.64 ± 0.56%) among the treatments. The results of the organosensory test showed thatthe application of biofloc systems produced a higher quality of fish meat with a range value of 7–9 compared to thatof the control with a range of 6–7. In conclusion, the application of biofloc systems could improve the fish healthstatus, growth performance, and meat quality of African catfish.

Abstract This study was conducted to assess the effect of water quality of the Ogun River on the haematological indices of the African catfish Clarias gariepinus. Samples of water and Clarias gariepinus were collected from Ogun River (Station I, Opeji and Station II, Lafenwa) to determine and compare effects of possible differences in water quality on haematological parameters of Clarias gariepinus. The results demonstrate that higher index values were recorded at station II than Station I for almost all the physicochemical parameters and only sulphate values from Stations I and II were statistically significant (P < 0.05).

Ortho-phosphate inside recirculation aquaculture systems is limited as a consequence of precipitation and regular water exchange rates. To improve plant growth in coupled aquaponics, phosphate fertilizer addition to hydroponics can increase PO43−-P concentrations inside the process water. We investigated the effects of four PO43−-P concentrations (<10 (P0), 40, 80, 120 mg L−1) in rearing water on growth performance, feed efficiency, and welfare traits of juvenile African catfish (Clarias gariepinus Burchell, 1822). By trend, optimum specific growth rate of 2.66% d−1 and feed conversion ratio of 0.71 were observed at 40 and 80 mg L−1 PO43−-P. Higher PO43−-P significantly affected skin coloration, swimming activity and external injuries, with the palest and inactive fish combined with most external injuries in the P120 group. Mineral and protein contents in the fish remained unaffected, while fat content inside the fillets enriched with increasing PO43−-P. Inorganic P in blood plasma increased significantly, while phosphate concentrations inside the fillet remained unchanged. We suggest that PO43−-P concentrations of 40 to 80 mg L−1 do not reduce the performance of African catfish aquaculture, while increased values of 120 mg L−1 affect fish welfare. This allows limited addition of PO43−-P fertilizer in coupled aquaponics with African catfish to support plant growth.

Effect Of Feeding

 No or little information on the use fresh (wet) housefly maggots (Musca domestica) in African catfish (Clarias gariepinus) fry feeding. Therefore, this study was conducted to investigate the effect of feeding on fresh (wet) housefly maggots with or without artificial diet on water quality, growth performance, survival percentage and feed utilization of African catfish fry under laboratory conditions. Housefly maggots produced from a mixture of poultry droppings and foods wastes, it was used to replace artificial feed at 0, 50 and 100% levels. Catfish were fed artificial diet alone (Feed 1), fresh (wet) housefly maggots alone (Feed 2), and 50% fresh housefly maggots with 50% artificial diet (Feed 3) were prepared and tested on triplicate groups of African catfish fry (initial weight of 0.25±0.02 g) for 60 days. Results showed that final weight (g/fish) was significantly highest (P£0.05) in fish fed feed 3 (6.03±0.08), followed by fish fed feed 2 (4.62±0.27), followed by fish fed feed 1 (3.15±0.68). Specific growth rate (%/day) was also significantly highest in fish fed feed 3 (5.31±0.10), followed by fish fed feed 2 (4.86±0.03), followed by fish fed feed 1 (4.18±0.24). The same trend was observed with total weight gain, percentage weight gain, daily growth rate and relative growth rate. Feed intake and protein intake were significantly highest (P£0.05) in fish fed feed 3 and fish fed feed 2, followed by fish fed feed 1. While, feed conversion ratio (FCR) and protein efficiency ratio were not significantly (P>0.05), but the improvement in FCR recorded in catfish fry fed feed 3 and feed 2 under the experimental conditions. Survival percentage was within the range 55–75%, with insignificant differences (P>0.05) among treatments. The water quality parameters such as temperature, pH, dissolved oxygen, total ammonia, nitrite and nitrate were not significantly (P>0.05) among the treatments and were tolerable for fish culture. Accordingly, use of the 50% fresh (wet) housefly maggots with 50% artificial diet in African catfish fry feeding had positive effect on growth performance and reduce of the feed cost.

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.

This study aims to determine the effect of artificial feed by adding cassava leaf flour (Manihot utillisima) to the water quality of the African catfish nursery pond (Clarias gariepinus). This study used the T test (one sample T test) to compare the treatment with artificial feed and commercial feed consisting of 3 replications. The feeding dose was 3% of the weight of the fish for 30 days of maintenance with the frequency of feeding twice a day. Parameters observed were NH3, NO2, NO3, pH, temperature, DO and survival of African catfish. The results showed that the provision of artificial feed in the African catfish nursery did not have a significant effect (P> 0.05) on the observed water quality parameters. The quality of water obtained during maintenance by providing commercial and artificial feed is still supporting the survival of African catfish.
