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.
