Diurnal Dynamics of Activity of Peptidases at Early Ontogenesis of Bleak Alburnus alburnus (L.) from Coastal Shallows of the Rybinsk Reservoir

详细

The diurnal dynamics of the activity of peptidases in fish larvae by the example of bleak Alburnus alburnus (L.) as the dominant species in the open and protected shallows of the Rybinsk Reservoir has been studied for the first time. Two peaks of enzyme activity in the intestinal mucosa of fish larvae are revealed: morning and night. The data on species composition and daily dynamics of number of fish larvae in the shallows of different types are presented.
