The main aim of this research is to develop a mathematical model to predict the dissolved oxygen in recirculating aquaculture system. The oxygen consumption of the model through the fish respiration and nitrification and the oxygen addition of the model through oxygen generator and water pumping. The effect of different water temperatures (24, 26, 28, 30 and 32 °C) on the dissolved oxygen consumption through fish respiration, biofilter and nitrification and fish growth were studied. An experiment to measure oxygen consumed by fish respiration and biofilteration and fish growth with the growth period and to validate the model results was carried out. The oxygen consumption predicted by the model was in a good agreement with those measured by the system. The oxygen consumption by fish respiration ranged 12.04 to 47.53 g O2 m−3 h−1 experimentally, while it was from 12.01 to 46.06 g O2 m−3 h−1 theoretically. The predicted and measured oxygen consumption through biofilteration values ranged from 0.43 to 21.91 and 0.45 to 23.09 g O2 m−3 h−1, respectively. The individual fish weight from the system ranged from 3.00 to 209.52 g experimentally while it was from 3.00 to 226.25 g theoretically during the whole period.

“…Summerfelt [68] stated that fish reared in tanks reduce their consumption rate but increase in density (Kg/m 3 ) and thus water flow rate has to be increase to reduce oxygen depletion. These low values could be associated with the period of sampling [69] given that sampling was done in the morning hours (6:30-7:30 am). In fact, Boyd and Lichkoppler [48] and Francis-Floyd [66] observed that dissolved oxygen is lowest in the early morning just after sunrise.…”

The present study was carried out to assess the effect of water quality on survival and weight of tank-raised Clarias gariepinus fed with commercial and farm-made feeds. Nine hundred juveniles (15.15± 3.48g; 128.366± 9.67mm) were stocked in 09 IBC (Intermediate Bulk Container) tanks (1m3 each) at a density of 100 fish/tank and fed with imported (Le), locally pelleted (Lpe) and locally extruded (Lex) feeds thrice a day for 16 weeks. Water quality parameters (water temperature, suspended particles, turbidity, colour, total dissolved solids, electrical conductivity, pH, dissolved oxygen, nitrates, nitrites, ammonia and phosphates) were measured every fortnightly using standard methods. Survivals were determined from the initial and final counts of studied fish and body weight was determined biweekly using a sensitive electronic balance. Regardless of dietary treatments and rearing period, studied water parameters did not differ significantly (p>0.05) except for Total Dissolved Solids (TDS), electrical conductivity (EC), pH and nitrites (p<0.05). The study also revealed that all the parameters were within acceptable or desirable ranges for fish farming except for dissolved oxygen and ammonia which were below (<3mg/l) and above (>0.05mg/l) optimal recommended ranges respectively. In addition, water temperature, turbidity, total dissolved solids, pH and ammonia had a significant effect (p<0.05) on the survival and weight of African catfish. The study concluded that dissolved oxygen and ammonia could have detrimental effects on studied fish growth. However, the fact that the studied fish were exposed short term in holding water as an exchange of water was carried out every day and a complete exchange every fortnightly with well oxygenated water, significantly contributed in reducing the abnormal contents of dissolved oxygen and ammonia. This implies that if best management practices are respected, the studied feeds will not deteriorate holding tank waters and thus not affect fish productivity.

“…All the parameters were within standard limits for aquaculture as recommended by Boyd [33] except for dissolved oxygen which had low values (<3mg/L). This could be attributed to the time of sampling [34].…”

The present study was carried out to determine the haematological and serum biochemical profiles of Clarias gariepinus juveniles fed commercial and farm-made feeds and reared in intermediate bulk containers (IBC) tanks. Nine hundred juveniles (15.15±3.48g; 128.37± 9.67mm) were stocked in 09 IBC tanks (1m3) at a density of 100 fish/tank in triplicate and fed with imported extruded (Le), locally pelleted (Lpe) and locally extruded (Lex) feeds thrice a day to satiation for 16 weeks. At the end of the experiment, blood samples were collected from 10 fish/ dietary treatment to determine haematological and biochemical indices. Results revealed that Red Blood Cells Count, Packed Cell volume and Haemoglobin concentration were highest (p<0.05) in fish fed with “Le” feed while Mean Cell Haemoglobin Concentration, Mean Cell Haemoglobin, Mean Cell Volume, White Blood Cells Count, Lymphocytes, Monocytes, Granulocytes and Platelets showed no significant difference (p>0.05) among the dietary treatments. As for serum biochemistry, Total Cholesterol and Glucose were highest (p<0.05) in fish fed with “Le” feed while Total Protein, Alanine Transaminase, Aspartate Transaminase and Alkaline Phosphatase were significantly higher (p<0.05) in fish fed “Lpe” and “Lex” feeds. Conclusively, variation of dietary treatments was not detrimental to the health status of C. gariepinus reared in plastic IBC tanks.
