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.

African catfish (Clarias gariepinus) is one type of freshwater fish that has high economic value. African catfish with intensive cultivation are hampered by the high cost of feed that is not in accordance with the selling price of African catfish. An alternative effort that can be done is the addition of probiotics to feed which is expected to reduce feed costs. Probiotics are living microorganisms in fish culture that can prevent disease, thereby increasing production and can reduce economic losses. This study aims to analyze the effect of probiotics on the growth of absolute weight and daily growth rate of African catfish. The method used was Completely Randomized Design (RAL) with 4 treatments namely 0, 2, 4 and 6 ml / kg of feed and repeated 3 times. Activities carried out in this study include preparation of containers, seed stocking, fish sampling, feed preparation, feeding and water management. The variables observed were absolute weight growth and daily growth rate. The results showed that the addition of probiotics to commercial feed significantly affected the growth of weight and daily growth rate of African catfish

Catfish is a species of freshwater fish that contains a source of protein and it has economic value and has become one of the famous commodities in Indonesia. Biofloc can be one alternative waste fixers intensive cultivation for reduce the waste of inorganic nitrogen and also provide additional protein for increase growth and feed efficiency. This study was to determine the effect of high stocking densities on the growth performance of african catfish in biofloc system. This study used completely randomized design (CRD) with different stocking densities in the system biofloc T1.(1000/m3), T2.(1500/m3), T3.(2000/m3), and T4.(2500/m3). Animal trials were using jouvenile african catfish with an average weight of 1.06±0.3g, which maintained in a pool tarpoulin cage with water volume ±2000L for 50 days with feeding ratio 3% of the weight biomass. The results showed a significantly different effect (P<0.05) against the value of hepatosomatic index, absolute growth and daily growth rate, but the result not significant at spesific growth rate. The second treatment (T2) showed the best results than others in the growth rate and daily growth rate with a value of 6.45±3.1g for absolute growth and 0.13±0.06g for daily growth rate. The four treatment showed the best results than others in the hepatosomatic index with value 4.7 ± 1.8%. These findings demonstrate a role of biofloc technology in catfish aquaculture.

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.

 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.

The experiment was designed to evaluate the effect of egg size on hatching quality and post-hatch growth performance of normal feathered indigenous chickens. Hatchable eggs, grouped into three sizes: medium/control, small and large, were incubated to obtain day-old chicks. One hundred and eighty (180) day-old chicks were allotted to three treatment groups according to the egg sizes from which they were hatched. Egg size significantly (p<0.05) influenced chick hatching weight. Chicks hatched from large eggs were the heaviest (36.89g) while those obtained from small ones were the smallest (31.02g). Daily growth rate (DGR) was progressive and uniform in both cockerels and pullets in the first 8 weeks of life across the treatment groups. It was concluded that egg size, though could determine chick hatching weight, but not a good predictor of post-hatch growth performance in normal feathered indigenous chickens

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.
