THE ACTIVITY OF LYSOSOMAL PROTEASES IN THE ORGANS OF FEMALE THREESPINE STICKLEBACK (GASTEROSTEUS ACULEATUS LINNAEUS) IN THE SPAWNING PERIOD
The results of a study on the spawning-period activity of lysosomal proteases (cathepsins B and D) in the organs (muscles, liver, gills, gonads) of threespine stickleback ( Gasterosteus aculeatus L.) from hydrologically and ecologically different White Sea habitats are presented. At the beginning of...
