CHARACTERISTICS OF PROTEINASE ACTIVITY OF PREYS OF FISH-ICHTHIOPHAGOUS WITHIN A BROAD ZONE OF pH
Year: 2024
Type: conference-paper
Abstract: The influence of pH on the activity of proteinases functioning in the body of fish – potential prey of fish-ichthiophagous (rudd Scardinius erythropthalmus, roach Rutilus rutilus heckeli, ruff Acerina cernua, goby Neogobius fluviatilis) from Cuciurgan reservoir was investigated. It is shown that the level of activity of proteinases in tissue homogenates of fish largely depends on the pH. Maximum activity of proteinases of the whole organism in a ruff and goby is at pH 8, in rudd and roach it is at pH 10. Proteinase of the tissues in fish-benthophagous can function effectively in acidic pH zone.
