To measure the digestive enzymes activities, the hepatopancreas samples were weighed and homogenized in 10 volumes (v/w) of pre-chilled phosphate buffer solution (pH 7.3). The homogenates were then centrifuged at 2500 r min1 for 30 min and the supernatants were collected. Amylase activity was determined by using the iodinestarch colorimetric method by utilizing assay kits from Nanjing Jiancheng Bioengineering Institute (Cat. No. C016, Nanjing, China). Total protease and lipase activities were measured by using enzyme-linked immune sorbent assay (ELISA) kit purchased from Shanghai Hengyuan Biotechnology. One unit of amylase activity (U mg1 protein)was defined as one mg substrate hydrolyzing 10 mg starch in 30 min at 37°C. The protein concentration of supernatants was measured as described by Bradford (1976).
