Abstract

The investigation was aimed at determining the effect of biofilter on the
environmental parameters and growth of goldfish. The goldfish were reared in the flowthrough circular cement cisterns connected with biofilter unit and
without biofilter. The important environmental parameters were estimated
for a period of two months. The water pH and DO levels showed diurnal
variation. The mean gross fish production was higher in the tank fitted with
biofilter ( 291g /5m3)than the tank without biofilter ( 260g / 5m3).
