Abstract The mudskipper Boleophthalmus pectinirostris and Chinese black sleeper Bostrichthys sinensis occupy the intertidal zone. However, both species have their own unique diet. The former is an herbivore and the latter is a carnivore. In order to reveal the relationship between digestive enzyme activities and diets in the two species, the activities of protease (P), non-specific bile salt-activated lipase (BAL) and α-amylase (A) were determined in the stomach and intestine of adult mudskipper B. pectinirostris and Chinese black sleeper B. sinensis. The results showed that the activities of protease, BAL and α-amylase in the intestine of B. pectinirostris were significantly (P0.05), while BAL and α-amylase activities of the intestine were significantly (P
