Exploitation of fish stocks

This research programme produces knowledge on the stocking of fish, the impact of fishing, the biodiversity of fish stocks. Information is needed to plan, carry out and assess the results of the management of fisheries.

The programme consists of 20 projects, among which the most important subject areas are

1. regulation of fishing

2. success of fish stocking

3. biodiversity of fish populations

The tagging of fish is often used to aid research into the management of fish stocks. Tagging helps us to increase our knowledge of the migration, growth, and catches of fish.

Improving the state of fisheries

The guide “Kalavedet kuntoon (In Swedish: “Bättre fiskevatten) provides useful information on how to select ideal fish species and high-quality young of fish and crayfish for stocking and how the mesh size of a net affects the size of the fish caught.
