Ushakova, V. Kuz'mina] The paper cites evidence on the activity of casein- and hemoglobinlytical proteinases of mucosa of the digestive tract of nine species of freshwater bony fish differing in their pattern of feeding, as well as in the whole organism of their potential prey. It was demonstrated that the ratio of proteinase activity with respect to casein and hemoglobin in the intestine mucosa of consumers and in the whole organism of their food items is different. In mucosa of fish intestine, the activity of caseinlytic proteinases is higher than the activity of hemoglobinlytic proteinases. In the whole organism of juvenile fish and invertebrates, on the other hand, the activity of hemoglobinlytic proteinases is higher.
