The paper continues the series of studies aimed on analyzing the biological processes taking place in the coastal zone of the Barents Sea. The size and weight parameters, age and sex structure, as well as the feeding of juveniles of Atlantic cod and saithe in the intertidal zone. There are pronounced seasonal changes in the studied parameters. Gammaridae play a large role in nutrition, but cannibalism is well-pronounced. Malformation of the otolith structure is recorded. The data obtained may be used for further monitoring or applied for the ecosystem modeling.
