“…Studies on Clarias gariepinus nutrition abound, some of these include Aderolu et al [9], Mustapha et al [10], Dienye and Olumuji [11], Obe and Omodara [7], Ofor and Afia [4], Umanah and Harry [12], David and Afia [13] and Umanah et al [14]. The well-being of fish can be impacted by under or overfeeding as a number of poor indices may set in such as pronounced decline in water quality, poor nutrient utilization, reduced biomass and pronounced vulnerability to diseases [15].…”

Background: As other animals, fish needs essential nutrients to enable metabolic activities including growth, reproduction, repairs, etc. In fish culture practices, studies on the quantity and rate of feeding are aimed at identifying the optimum level/ration. Objective: This study evaluated growth performance, feed utilization and survival of Clarias gariepinus fingerlings fed varying feeding levels diets in tarpaulin tanks for 14 weeks (August-November, 2019). Methodology: The experiment was carried out at Fulfillment Fish Farm in Uyo Metropolis, Nigeria using 9 tarpaulin tanks of 1M 3. Three (3) feeding levels were chosen as treatments with triplicates. These were 2%, 4% and 6% fresh body weight of the fish and were designated as 2FL, 4FL and 6FL respectively. Twenty-five fingerlings each was randomly stocked in the tanks (25fish/m 2) and starved for 24 hours before the commencement of the feeding trial and the initial mean weight (3.69±0.01 g) was measured. The fish was fed twice daily (08:00 hrs and 16:00 hrs) at 2%, 4% and 6% respectively with Alaqua feed at 42% crude protein. The feeding rate was adjusted fortnightly with increase in body weight. Results: Results showed significance (p<0.05) in mean final weight, mean weight gain, specific growth rate, percentage weight gain, performance index, feed conversion ratio and protein efficiency ratio across the feeding trials with 6FL having highest growth response and 2FL having better feed utilization. Survival rate and mortality rate were non significant (p>0.05) across treatments. Conclusion: On the basis of growth response, feeding African catfish (C. gariepinus) at 6% body weight per day is recommended for raising African catfish at reduced cost of production.

“…Whether floating or sinking, a good feed should contain essential nutrients (protein, lipids, minerals, vitamins, etc. ) in the right proportion with proper formulation that meet the nutritional requirements of cultured fish (Mustapha ., 2014) Feeds offered to fish should be fresh, durable in water until they are eaten, and must be attractive and palatable to fish at a reasonable cost that will yield profits to farmers (Diyaolu, 2012). Most of the available commercial sinking pellets in Nigeria do not meet these criteria, which explain why farmers prefer to use floating feeds rather than sinking pellets.…”

“…Generally, selection of feed for aquaculture requires accurate information on the nutrient composition, growth efficiency and other important characteristics of the feed in relation to the nutritional requirement of the cultured (Diyaolu, 2012). Research on efficiency of commercial feeds till date mainly focuses on comparing growth responses of fish fed with locally made fish and imported feed (Ekanem, 2012;Mustapha ., 2014;Limbu, 2015).Reliable scientific evidences are lacking on most commercial floating feeds available in the country, despite that these feeds are being extensively used by farmers with varying results. This study was therefore aimed at examining pr oximate compositions of three commonly used commercial floating feeds in Nigeria and their effects on survival and growth performance of juveniles in order to determine whether all floating feeds have similar growth effects on fish (Ali, 2012;Limbu, 2015).…”

There is paucity of information regarding efficiency and suitability of most imported floating feeds used for growing catfish in Nigeria. This study therefore determined proximate compositions of three commercial floating fish feeds (Vital Feed, Top Feed and Allier Aqua Feed) and their effects on growth parameters when fed to juvenile African catfish (Clarias gariepinus). 65 litre capacity rectangular plastic tanks were stocked with healthy juveniles catfish of similar average weight were fed with these feeds for a period of 56 days (8weeks at the rate of 20 fish per tank. A triplicate trial was maintained for each feed, totalling nine tanks in all and 60 fish per feed. The tanks were labelled based on the type of feed. The rearing water quality parameters were monitored throughout the experiment. The results indicated that catfish fed with Top Feed had significantly (p80%) were observed in all groups while water quality parameters were not affected due to the feed offered. The results of the proximate composition attested to the fact that feed with high protein and lipid contents results in better fish growth i.e. Top feeds with high protein (45.16±2.73) and Allier Aqua with high (13.00±2.11) content. Variations in growth parameters and estimated cost of feeding observed in the present study imply that catfish that catfish farmers should exercise great caution in selecting commercial floating feeds for their fish since these feeds produce different growth effects on fish.

“…Most studies have found that the best feed for optimal fish production in aquaculture is feed rich in protein, the amount of which varies among different fish species recording a percentage of 30 to 60 (Mustapha et al, 2014). The ammonia excreted through the gills and feces is the end product of digesting the present protein in fish feed.…”
