Abstract

Changes in proteolytic activity in the gut, hepatopancreas and muscle of the plankton feeder sliver
carp, Hypoptuhalmichthys molilrix, and the camivore magur. Claries batrachus, were studied. Both
silver carp and magur exhibited seasonal variation in the proteolytic activity. Highest activity was
observed in gut section II in silver carp whereas it was in gut section I in magur. In silver carp, 4 peaks
were observed, during December, February, April and June, whereas 2 peaks were seen in magur,
during December and March. Enzyme activity of hepatopancreas was higher in magur than silver carp.
No significant variation was observed in the protease activity of muscle in both the species
