Abstract
The information available reveals pronounced changes in the ion ratio when marine and fresh waters are mixed. The critical salinity has been shown to be about 5%. in the Kara, White, Baltic, Azov, Black and, probably, Caspian Seas, and British Columbia. Corresponding results were obtained in experimental mixings of White Sea waters with a variety of fresh waters. A close connection is suggested between mixed water hydrochemistry and the existence of an eco-physiological barrier. This barrier divides, at salinities of 5 to 8%., the two basic types of aquatic animals into marine and freshwater representatives.
