“…Catfish farmers used more of local feed (79.57%, 88.41%, 80.56% and 82.48% in Edo South, Edo Central, Edo North and Edo State respectively). This agrees with Ekanem et al (2012) who compared the growth performance and food utilization of catfish feed on local, midst and import feed and concluded that locally formulated feeds are good alternative in catfish production. More of family and hired labour (60.26%) was also used in the area.…”

The continuous importation of fish portends a colossal loss of foreign exchange reserved to Nigeria which requires urgent attention to boost fish production. It is against this backdrop that this study analyzed the profitability analysis of catfish production in Edo State, Nigeria. It specifically describe the production characteristics of the catfish farmers, estimate the input and output quantities of catfish, determine the profitability and identify the constraints associated with catfish production in the study area. Multi-stage sampling procedure was employed to select a total of 468 catfish farmers from the study area. Data collection was achieved through the administration of structured questionnaire. Data analysis was done using descriptive statistics, budgetary techniques and 4-Point Likert-type scale. The results revealed that the farmers in the study area used more of personal savings (58.12%), family land (59.40%) and local feed (82.48%). Stocked more at juvenile stage (70.30%) and produced average output of 4859.51kg per production cycle. The results also showed the average total cost incurred and revenue realized were N 543.67 and N 752.56 per kg fish respectively. The catfish production was profitable with average gross margin, net profit and return per naira invested of N224.35, N208.90 and N1.38 per production cycle respectively. The major constraints faced by catfish farmers were high cost of food (3.96), lack of capital (3.65) and lack of inadequate power supply (3.51) are very serious constraints among others. Since the catfish production was profitable, the farmers should be encouraged to combat these constraints and expand their holdings to boost production.

“…This can be attributed to the components which gives an odour of fish to Coppens feed and its floatable nature. This finding agrees with the findings of [26,27], who in their report stated that business feeds like Coppens, Vital, Multifed, and Euro, release a stronger odour that is fishy in nature. Going by Coppens manufacturer's label, the constituent macronutrients differed from ingredients used in formulating shrimp based diet (SBD) and chicken offal based diet (COBD), although some ingredients and additives were almost the same.…”

“…Since feed are costly, FCR or FCE are important factors for the accurate use of feed [28]. Research has consistently highlighted that good knowledge of FCR helps the farmer to satisfactorily feed the fish [29,30,31,32,33,34,27]. In this study, Diet A were more readily converted by fish as indicated by the high FCR and FCE, followed by Diet B and then Diet C as the least.…”

A comparative study on the growth performance of African catfish (Clarias gariepinus) fed shrimp based diet (SBD), chicken offal based diet (COBD) and coppens feed was carried-out for 22 weeks in concrete tanks measuring 3.5 x 1.7 x 1.5 m3. Triplicate groups of 40 juveniles with average length of 9.15 ± 0.17cm and weight of 20.00 ± 2.58g were stored in each tank. A total of 360 juveniles were used throughout the study. Fish were fed daily at 3% of their body weight through-out the duration of the experiment. The nutrient composition of the 3 nutrients differed significantly at p<0.05. Weight gain (WG) (g) was highest (17189.33 ± 506.61g) in fish fed diet A (Coppens feed), followed by 15045.33±202.42 g (diet B) (SBD) and least (14357.33 ± 108.25 g) (diet C) (COBD). The Growth rate (GR) was highest in fish fed with diet A (111.62 ± 3.29 g/day), followed by 97.69±1.31 g/day (diet B), and least (93.23±0.70 g/day) in diet C. Specific growth rate (SGR) was highest in juveniles fed diet A (2.02 ± 0.02 %/day), followed by 1.94±0.01 %/day for diet B, and least (1.91±0.01 %/day) for diet C. Mean growth rate (MGR) was highest in juveniles fed diet A (11.88 ± 0.29 mg/day), followed by 11.74±0.15 mg/day for diet B, and least (11.69±0.09 mg/day) in fish fed diet C. The WG, GR and SGR varied significantly between the juvenile fish group fed the 3 diets at p<0.05, while MGR did not vary significantly between fish group fed the 3 diets at p>0.05. Fish fed diet A had a higher feed consumption (FC) (41650.00 ± 315.34 g/kg), than that fed diet B (39034.24 ± 86.34 g/kg) and then diet C (38276.00 ± 342.97 g/kg). Juveniles fed Coppens feed did better, with a feed conversion ratio (FCR) of 2.42 ± 0.06, followed by 2.59±0.04 for diet B and 2.67 ± 0.03 for fish fed diet C. Feed conversion efficiency (FCE) was higher in fish fed diet A (41.26±0.94 %), followed by 38.54 ± 0.54 % (diet B) and least (37.52 ± 0.51 %) (diet C). The FC and FCR varied significantly between the fish fed the 3 diets at p<0.05, while FCE was not significantly different between the 3 treatment groups at p>0.05. The water parameters of the culture water varied significantly between each treatment groups (p<0.05), and were within the rage suitable for normal growth of fish. Though coppens feed yielded better growth performance and feed utilisation, the use of COBD and SBD is recommended for fish farmers in Nigeria. More researches should be carried out on using chicken offals and shrimps in fish feed formulation.

“…The present study revealed that fish fed diet A grew faster than fish fed diet B, while fish fed diet C had the slowest growth based on the growth parameters studied. This could be attributed to the fact that coppens (diet A) are floatable and with strong fish odour to attract fish, which are attributes lacking in diets B and C. This finding agrees with [19,20] who in their report stated that business feeds like Coppens, Vital, Multifed, and Euro, release stronger odour that is fishy in nature. Agbokei et al [19] also reported that C. gariepinus like most catfish feed mostly using olfactory senses, which makes them more attracted to coppens as a result of its strong fish odour.…”

Economic performance of using Coppens (commercial fish feed) and locally formulated feeds for Clarias gariepinus culture was studied. Forty juveniles averaging a total length of 9.15 ± 0.17cm and weight of 20.00 ± 2.58g were used and fed twice daily at 3% of their body weight. The weight gain (WG), growth rate (GR) and specific growth rate (SGR) varied significantly (p<0.05), while mean growth rate (MGR) varied insignificantly between treatment groups (p>0.05). Water parameters were at the required level. Cost of experimental feed per kilogram was highest in Coppens (₦733.33 ($2.156853)/kg) but lowest for chicken offal based diet (COBD) (₦267.00 ($0.785294)/kg). Feed consumption was higher for Coppens group (41650.00g ± 315.34) but lowest for COBD group (38276.00g ± 432.97). Cost of feeding (FC) was lower for COBD group (₦ 10219.69 ($30.057912) ±115.60) but higher in shrimp based diet (SBD) group (₦ 30,543.19 ($89.832912) ± 231.25). The ICA was higher in fish fed Coppens (₦ 1933.33 ($5.686265) ± 0.00) but lower for COBD group (₦1467.00 ($4.314706) ± 0.00). The NPV was higher in fish fed Coppens (₦ 440998.26 ($1297.053706) ±11636.93), but lower in COBD group (₦ 132916.16 ($390.929882) ± 3297.24). The PI was highest in Coppens group (₦14.44 ($0.042471) ± 0.35) but lowest in COBD group (₦ 13.01 ($0.038265) ± 0.43). The GP was higher in Coppens group (₦439064.93 ($1291.367441) ± 11636.93) but lower in COBD group (₦131449.16 ($386.615176) ± 3297.24). The IC was higher in Coppens group (₦228.10 ($0.670882) ± 6.02) but lower in COBD group (₦90.61 ($0.266500) ± 2.25). The BCR was higher in fish fed coppens (1.78±0.04) but lowest in COBD group (0.71±0.01). Feed consumed, FC, ICA, NPV, PI, GP and IC varied significantly (p<0.05), while BCR varied insignificantly (p>0.05) between treatment group. The SBD and COBD were as effective as Coppens in terms of growth performance and economic benefits. More researches should be carried out on the use of locally formulated feeds in aquaculture.
