Hedströmmen Bernshammar

FISHING BAN 1/10 - 31/12 The spawning season for trout will soon begin. During this time, the fish are extra vulnerable and need peace and quiet for reproduction to succeed. By letting the fish spawn in peace, we contribute together to long-term sustainable and viable fishing in the nature conservation area. Hedströmmen is well visited by anglers from all over the Mälardalen region. There is a local stock of trout in Hedströmmen, but the local stock is far too small for sport fishing. In order to withstand sport fishing, the river is strengthened with support releases. These support releases are the offspring of wild-caught parents that have been squeezed onto roe and allowed to hatch at the fish farm in Kloten. So it has been decided to introduce Catch and release for ALL trout, i.e. that they are released again. The trout must become more numerous for freshwater pearl mussels to be able to try their hand. The mussels spend the first period of their lives attached to the trout's gills. There they develop from larvae into small mussels. Without this transformation, there cannot be more mussels. The farmed trout that were previously released for fishing unfortunately do not function as host fish for the mussels. Therefore, a healthy population of local trout with good regeneration is needed.
