Studies on the effect of dairy effluent on survival and feeding energeticsin Cyprinus carpio.

The effect of dairy effluents on survival and feeding energetics of the com mon carp Cyprinus carpio were studied. At a concentration of 35% effluent 1 00% mortality was recorded within 24 hr; no mortality occurred at 10% withi n 96 hr exposure. Concentration of 25% effluent was found as median lethal concentration at 96 hr exposure. Rearing the fish in increasing sublethal c oncentrations of dairy effluent (2.5 and 5%) food consumption of fish incre ased. (From 305.72 +/- 18.03 mg/g to 404.595 +/- 8.36 mg/g live fish at 2.5 % and 395.82 +/- 11.55 mg/g live fish at 5% respectively). However, the gro wth rate and conversion efficiency registered:a marked reduction.
