• The optimal conditions for proteolytic and esterolytic activities in the digestive tract of octopus, Octopus vulgaris CUVIER, were reported together with the change of proteolytic activity after spawning. Glycerin extracts of liver (including pancreas) and posterior salivary gland showed strong proteolytic activities in acidic and alkaline regions, respectively (Figs. 1 and 2). These activities, however, decreased considerably after spawning and only one tenth of activities in the liver and one thirtieth in the posterior salivary gland were reserved, as shown in Table 3. On the contrary, weak proteolytic activities found in stomach and intestine did not show any changes after spawning. Decrease of food intake after spawning seems to connect with the changes of the enzymatic activities in the liver and posterior salivary gland. The weak esterolytic activity to β-phenolates was also observed in the digestive tracts.
