Abstract

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.
