The lowest values of plant consumption were found in treatment of
effluent fish water at a flow rate of 2 L min-1 with length of gully 4 m and
the highest values were recorded at a flow rate of 1 L min-1 with length
of gully 2 m. Increasing the velocity of water in gullies with increasing
the flow rate decreased the rate of nutrient consumption. These results
agreed with those obtained by [23-25].
