Bello-Olusoji, O.A. | Ogunwo, F.M.
Juveniles Macrobrachium vollenhovenii prawns were collected from Epe lagoon and reared for 56 days in concrete tanks with purely freshwater. Production rate of Nitrogenous compounds were monitored. Analysis of the water quality variables were carried out weekly and the range of each parameters were 6.74 7.90 (pH), temperature ranged between 25.7 and 30.3~?C, 6.71 8.01 mg/L for dissolved oxygen, 0.00 0.03% for Salinity, 0.199 0.725 mS/cm for conductivity, 24 48 NTU for turbidity), nitrite ranged from 0.07 to 0.50mgIL, nitrate was 1.32 6.63mgIL, and 0.32 1.65mgIL was recorded for ammonia.
