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).

Water quality and waste management are significant problems for aquaculture in Indonesia, including catfish (Clarias gariepinus) aquaculture. A combination of Aquaponics Systems and Recirculating Aquaculture Systems (A-RAS) has been developed to address this problem. This study analyzed A-RAS application for catfish (Clarias gariepinus) aquaculture by comparing water quality and production indicators between A-RAS and conventional methods. The results show that temperature, pH, dissolved oxygen, total organic matter, ammonia, nitrate and nitrite in A-RAS technology were 28.0-30.0°C, 6.5-7.9, 3.8-7.8 mg/L, 18.54-24.97 mg/L, 0.12- 0.28 mg/L, 0.12-0.13 mg/L, and 0.04-0.13 mg/L, respectively. Survival Rate, Feed Conversion Ratio, and harvest in A-RAS application were 85.5%, 1.1, and 26 kg/m³, respectively. A-RAS technology can maintain water quality to be reused in cultivation and increase yields by about 13%. Besides, water spinach can be an additional income for farmers.

Comparative study on African catfish hypophysation indices using ovaprim and chicken pituitary gland extract (CPGE) was carried out. Sixteen (16) African catfish brood stocks between 1100 and 2300 g in ratio 2:1 and four (4) numbers of layer birds (Gallus gallus domesticus) between 1200 and 2200 g in ratio 1:3 were used respectively. The experiment was batched into “A” and “B”. Batch ‘A’ was placed on ovaprim while batch ‘B’ was placed on CPGE. An indoor hatchery vat, measuring 0.6096 m x 1.8288 m x 0.3048 m each was used for the incubation. Digital measuring kits were used to monitor water quality parameters and measurement of the brood stocks weights independently. Brood stocks on ovaprim and CPGE treatments had the following mean hypophysation indices in these order: fecundity (11100±7690 and 17760±13863), latency period (9.53±0.54 and 9.77±0.49), fertilization percentage (94.03±5.90% and 90.6±10.11%), hatchability percentage (75.6±0.81% and79.35±10.27%), number of eggs produced (5889±657.37 and 9403.33±589.80), total number of larvae hatched (4717.33±1111.0 and 7111.33±506.64), SGR (0.67±0.31 and 1.1±0.31), and survival rate (64.81±0.71 and66.24±2.19) respectively. There was no significant difference (p = 0.05) in the mean values of fecundity, latency period, fertilization and hatchability percentages in both treatments but there was significant difference (p ≤ 0.05) in number of eggs produced and total number of larvae hatched in both treatments. The water quality parameters were within the range for induced breeding techniques and there was no significant difference (p= 0.05) in both experiments. Both ovaprim and CPGE had excellent results from the induced breeding of Clarias gariepinus and yielded good results. Therefore, CPGE could be recommended from the view point of excellent results and its availability from chicken slaughter houses as against ovaprim which are imported.

The biofloc technology can control water quality under negligible water exchange. The aim of this study was to evaluate the  effects of stocking density on production and blood performance of catfish (Clarias gariepinus [Burchell, 1822]). The catfish were reared in biofloc system (heterotrophic bacteria and addition of sugar for a period of 10 wk and used three levels of density i.e. (500, 1 000, and 1 500) fish per m2. The production increased with the increasing of stocking density, relative growth rate decreased with the increasing of that. The stocking density of 1 500 fish per m2 on the biofloc technology can support maximum catfish production, health and proper water quality.

 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.

ladosufan is an insecticide extensively used in agriculture for pest control. The 96h LC50 estimated from probeit analysis was 1.89mg/L. Sub lethal concentrations of 1/10th (0.19 mg/L),1/5th (0.49mg/L) and 1/2th (0.95mg/L) of LC50 were used to determine the effects of the ladosulfan -pesticide on biochemical parameters at day 1, 7, 14 and 21exposure periods. Water quality test was determined on pH, temperature, dissolved oxygen, hardness and alkalinity. The results show that biochemical parameters viz; Total Protein, Alkaline Phosphatase ALP, Alanine Transferase ALTAspartate Amino Transferase (AST) concentrations increased significantly (P ≤ 0.05) in time and concentration dependent manner. The biochemical parameters concentration had higher values in treated samples than control. The total protein increased from (8.80±0.002b -9.20±0.103b) at 0.19 mg/L, (9.20±0.102a –9.70±0.103c) at 0.48 mg/L and (9.27±0.152a –9.80±0.103c) at 0.95 mg/L of ladosulfan when compared with the control (7.67±0.931c –9.06±0.763c ); Alkaline Phosphatase increased from (60.00±0.002a -86.00±1.001b) at 0.19 mg/L, (62.00±1.002b –88.00±1.001c) at 0.48 mg/L and (65.00±1.001a –92.00±1.002d) at 0.95 mg/L of endosulfan when compared with the control (40.00±1.002a–53.67±5.511a) ; Alanine Transferase also increased from (30.00±1.002a -40.00±1.001c) at 0.19 mg/L, (35.00±1.002a –54.00±1.001a) at 0.48 mg/L and (38.00±1.002b –89.00±1.001d) at 0.95 mg/L of ladosulfan when compared with the control (22.33±2.083c –27.33±2.882b) ; Aspartate Amino Transferase increased from (64.00±1.002b -87.00±1.001c) at 0.19 mg/L, (66.00±1.002c –88.00±2.001d) at 0.48 mg/L and (68.33±0.582c –90.00±1.001d) at 0.95 mg/L of ladosulfan when compared with the control (63.00±2.002b –68.00±1.001b) ; respectively. The results indicate that commercial formulation of ladosulfan is toxic to C. gariepinus, the insecticide should be prudently used in both terrestrial and aquatic eco-systems to avoid eco-toxicological hazards.
