Fish care Restocking of trout and char, Removal of migration obstacles for spawning fish. Survey of fish stocks. Biotope measures in certain waters to benefit trout and grayling. We are working in particular to strengthen the natural production of trout through biotope care measures and the construction of spawning and nursery areas. In the summer of 2016, we used a helicopter to fly spawning gravel into Kvarnån Bodsjön and Länsterån In the summer of 2019, 200 tons of spawning gravel were flown into Ljungan to improve the opportunities for trout to spawn. The spawning grounds look to have become really good, now we hope that the migratory trout will find and take a liking to the new grounds.
