ABSTRACT: The aim of this study was to verify the activity of some digestive enzymes in four fish species with different feeding habits. Knowledge of these enzymatic activities can help us to understand the species' digestive processes. The species chosen for this study were Ctenopharyngodon idella (herbivore), Rhamdia quelen (omnivore), Leporinus obtusidens (omnivore) and Hoplias malabaricus (carnivore). The digestive tract of these species was divided into four portions to estimate enzymatic activity: stomach, anterior, mid and posterior intestine. Ctenopharyngodon idella had the highest amylase and maltase activities in all portions of the gut, followed by L. obtusidens . The highest trypsin activity was observed in all gut portions of H. malabaricus,...
