The growth character of the baltic salmon (Salmo salar) of the Russian part of the Gulf of Finland of the Baltic Sea

Popov, I.Yu.
There are three populations of Atlantic salmon in the Russian part of the Gulf of Finland of the Baltic Sea. Every one represents a specific pattern of growth character and correspondingly the scale pattern. The scales can be used for identification of salmons in respect to their origin. A gradual decrease of the average size of salmon was observed over last decades. This fact is partly related with the transition from natural to artificial reproduction of the populations, while the main reason is an intensive fishing. The intensive fishing results in decreasing of number of old and big fishes in the populations
