title: [Changes in the activity of trout lysosomal enzymes during fasting].
abstract: Activity of lysosome enzymes (acidic phosphatase, beta-glucosidase, DNAase, RNAase and cathepsin D) is determined for its variation in different organs of rainbow trout during complete fasting. It is shown that the activity of most enzymes of concern almost in all organs except skeletal muscles is on the higher level in trouts fasted for 30 days than in the control ones. With an increase of the fasting term to 60 days the acid phosphatase, DNAase, RNAase activity decreases while the glucosidase and cathepsin D activity in some organs increases. Variations detected in the enzyme profile of the trout lysosomes under fasting are of adaptive character.
