About the department

The basic aim of the Department’s activity is to develop and implement an ecosystem approach to the resources management, i.e. considering the impact of environmental factors on the living resources as well as the impact of fisheries on the exploited resources and the ecosystem.

These themes are approached through the following research fields:

  • Biology and the significance of fish populations in the Baltic Sea ecosystem, including:
    • determining the impact of natural and anthropogenic factors on the life processes and behaviour of fish (like reproduction, growth, feeding or migrations),
    • analysis of chosen parameters and characteristics of fish as bio-indicators for changes which occur in the environment,
    • genetic characteristics of the used resources, with a special attention paid to the possibilities of identifying populations.
  • Defining the dynamics and production of stocks of significant species of fish, which are caught as a part of Baltic and deep-sea fisheries, so that their resources can be used rationally.
