Hängasjöns FVOF is an active association that uses income from fishing license sales for measures such as planting fish and preparing vases etc. are not allowed by the county council to release more pike-perch!! so be sure to release those under 40 cm and those over 65 cm, otherwise the pike-perch will probably disappear.

In recent decades, pike-perch have been planted in the lake. A place has recently been made for launching boats.
