Abstract

The vertical distribution of larvae of the sea urchin Strongylocentrotus intermedius in conditions of superficial desalination was studied under laboratory conditions. In the earlier stages of development, the larvae accumulated in the water column zone with a salinity below the optimal level. The long-term observations of the larval accumulations revealed the deceleration of, and abnormalities in, the development and death of the larvae. The larvae at the pre-settling stages changed their behavior: when they reached layers of a salinity unfavorable for their survival or development, the larvae did not enter them and instead moved down instead. Obviously, S. intermedius larvae are only capable of actively choosing their position within the water column with the salinity gradient at the later stages of development.
