The White Sea threespine stickleback, Gasterosteus aculeatus, differentiation at the beginning of spawning by the activity of calcium-dependent proteases and population characteristics
Threespine stickleback Gasterosteus aculeatus of theWhite Sea perform spawning migrations from the wintering areas to the inshore zone in early summer. To describe the spatial heterogeneity of the spawning agglomerations of stickleback, we compared size characteristics and biochemical parameters in...
