Abstract

Mosunmola Florence AKINWUNMI, Oluayo Anthony BELLO-OLUSOJI

Juvenile-size of African River prawns (Macrobrachium vollenhovenii) of an average length of 46.34 ±0.23mm were collected from Epe Lagoon and cultured in concrete tanks for 56 days. The production of Nitrogenous compounds was monitored and the analyses of the water quality variables were carried out weekly. The range of the water quality variables were 6.74-7.90 (pH), 25.7-30.3°C (Temperature), 6.71- 8.01mg/L (Dissolved Oxygen), 0.00-0.03% (Salinity), 0.199 and 0.725 mS/cm (Conductivity), 24-48 NTU (Turbidity). The result showed that Nitrite (NO2 -) ranged between 0.07-0.50mg/L, Nitrate (NO3 -) was between the range of 1.32-6.63mg/L and Ammonia (NH3 -) was between 0.32-1.65mg/L.
