Effect of feeding on fresh (wet) housefly maggots (Musca domestica) with or without artificial diet on water quality and growth rates of African catfish (Clarias gariepinus Burchell, 1822) fry under laboratory conditions

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.

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.

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.

Lettuce (Lactuca sativa L.) and African catfish (Clarias gariepinus) were preferred to grow in aquaponics due to their high and fast productivity growth. However, limited research was conducted on the impact on different inorganic substrates’ growth performance in aquaponics. In this study, lettuce’s growth performance was determined in four different kinds of inorganic substrates in Nutrient Film Technique (NFT) aquaponics by measuring final weight, daily growth rate, stem diameter, plant and root lengths, leaf number per plant and shoot/root ratio. Polyester fiber, rock wool, zeolite, and gravel were used as inorganic substrate materials. A constant flow rate of 0.3 L/min was maintained using with a submersible pump motor. At the end of the study, the African catfish’s feed conversion ratio was estimated to be 0.66, while the specific growth rate (SGR) was 2.3%. Total lettuce yields for polyester fiber, rock wool, zeolite and gravel were obtained as 5.072,22 kg/m2, 4.934,03 kg/m2, 6.067 kg/m2, and 5.382,64 kg/m2 respectively. There were statistically significant differences for daily growth rate between the inorganic substrates that the significantly highest values were recorded in the zeolite. The results revealed that initial plant length and shoot/root ratio were the significant factors on the growth performance for lettuce in aquaponic system tested. The best lettuce yield performance was observed in zeolite substrate but, economically available option was found as gravel for hydroponic troughs.

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.

Growth performance, feed utilization, survival and body indices of African catfish Clarias gariepinus juveniles fed diets containing maggot meal as replacement of fish meal was evaluated for 42 days. Sixty fingerlings of Clarias gariepinus, average weight of 10 g were randomly distributed into six circular tanks at the rate of 10 fish per tank. There were two treatments, DT1(maggot meal-based diet) and DT2 (fish meal-based diet). The fish were fed twice daily. Water quality parameters were monitored on a weekly basis throughout the experimental period. Growth, nutrient utilization and body indices parameters were evaluated at the end of the experiment. Crude protein, crude lipid and ash were higher in the fish meal-based diet (34.65%, 7.33% and 18.03% in DT2 as against 28.70%, 7.20% and 11.0.1% in DT1 respectively), while crude fibre was higher in maggot meal-based diet. The selected water quality parameters: temperature, dissolved oxygen, ammonia and pH were slightly lower in maggot meal based treatment, but none of them was differently significant. Mean weight gain, specific growth rate, protein intake, protein efficiency ratio, lipid intake and lipid efficiency ratio (17.25±0.70 g, 2.39±0.06 %/day, 95.50±1.27 g, 1.81±0.06, 23.96±0.32 g and 7.20±0.24 respectively) were all significantly higher in DT2. The feed conversion ratio was higher significantly in DT1. Survival, hepatosomatic index and condition factor were similar between the two treatments. Though the aforementioned body indices indicated that the total replacement of fish meal with maggot meal is not harmful to the fish, a partial replacement may be better for optimum output

ABSTRACT This study was aimed to analyze the growth performance of African catfish Clarias gariepinus cultured in the biofloc system at high stocking density. African catfish with an average weight of 1.85±0.09 g were cultured in four units of tarpaulin tank at a diameter of 1.72 m and a height of 1.05 m with a volume of ±2,000 L at the different density of 1,000 fish/m3; 1,500 fish/m3; 2,000 fish/m3; 2,500 fish/m3. During rearing period, fish were given the artificial feed with protein contents of 28.75% with the frequency of twice a day, as much as 3% of the body weight. The results showed that different treatment of high stocking density in the biofloc system had a significant effect on the absolute growth rate, lipid retention and energy retention (P<0.05) but not significant effect on daily growth rate. The results showed that the highest lipid retention and energy retention were found in the group of fish treated at a stocking density of 2,500 fish/m3 but declining protein retention and growth in fish occurred. The highest absolute growth rate and daily growth rate were shown by treatment with a stocking density of 1,500 fish/m3. Keywords: growth, stocking density, biofloc ABSTRAK Penelitian ini bertujuan untuk menganalisis performa pertumbuhan ikan lele dumbo Clarias gariepinus yang dipelihara pada sistem bioflok dengan padat penebaran tinggi. Ikan uji memiliki berat rata-rata 1,85±0,09 g yang dipelihara pada kolam terpolin berdiameter 1,72 m dan tinggi 1,05 m dengan volume air ±2.000 L sebanyak empat unit dengan kepadatan yang berbeda yaitu 1.000 ekor/m3, 1.500 ekor/m3, 2.000 ekor/m3, 2.500 ekor/m3. Selama 40 hari masa pemeliharaan, ikan diberi pakan buatan berkadar protein 28,75% dengan frekwensi dua kali sehari, sebanyak 3% dari berat tubuh. Hasil penelitian menunjukkan bahwa perlakuan perbedaan padat penebaran tinggi pada sistem bioflok memberikan pengaruh yang nyata terhadap pertumbuhan mutlak, retensi lemak dan retensi energi (P<0,05) namun tidak memberikan pengaruh nyata terhadap laju pertmbuhan harian. Hasil penelitian menunjukkan bahwa semakin tinggi padat penebaran terjadinya peningkatan retensi lemak dan retensi energi yaitu pada perlakuan padat penebaran 2.500 ekor/m3 tetapi terjadi penurunan nilai retensi protein dan pertumbuhan pada ikan. Nilai pertumbuhan mutlak tertinggi ditunjukkan oleh perlakuan dengan padat penebaran 1.500 ekor/m3. Kata kunci: pertumbuhan, padat tebar, bioflok

Effect Of Feeding

This study was conducted to examine the effect of feeding at different time intervals of the day on the growth efficiency of African catfish (Clarias gariepinus, Burchell 1822). Juveniles of African catfish Clarias gariepinus with an average weight of 16.0±0.20g were randomly stocked into four treatment groups (T1, T2, T3 and T4) at 10 fish per group using a completely randomized design (CRD). The treatment groups were T1 (Fish fed once daily), T2 (Fish fed twice), T3 (Fish fed Thrice daily) and T4 (Fish fed four times daily). They were all fed 3% of their body weight. Data obtained was analysed using Genstat package while means where separated using Duncan Multiple Range Test. The result of the study showed that the highest weight gains of 104.49g was recorded in Treatment 3, this was followed by Treatment 2 with a mean weight gain value of 92.42g. The least value of weight gain (76.74g) was recorded in Treatment 1. Also, the highest feed intake value of 142.83g was recorded in Treatment 3, this was followed by Treatment 2 with a mean feed intake value of 135.12g. The least value of feed intake (112.95g) was recorded in Treatment 1. The feed conversion ratio and Protein Efficiency ratio (PER) also followed similar trend as that of weight gain and feed intake. The highest PER value of 2.10 was recorded in Treatment 3, this was followed by Treatment 2 with a mean PER value of 1.69. The least PER value (1.39) was recorded in Treatment 4. ANOVA showed that there was significance difference (P<0.05) in the PER value between Treatment 1, 2 and 3. However, Treatment 1 was not significantly different (P>0.05) from Treatment 4. At the end of the Study, three times feeding per day was found to be sufficient for maximum growth as it recorded the highest value for growth parameters monitored and was significantly different from other treatments.
