Abstract: | In Finland, small forest lakes and rivers in the northern part of the country are more sensitive to acidic deposition than
other Finnish waters. In some lakes, acid-sensitive fish populations have declined. A nationwide survey of fishers showed
that, at present, the number of fishers whose primary fishing waters are affected by airborne acidification is negligible
compared to the estimated total number of adult fishers (1.1 million). The proportion of the fishers who mainly fish in water
types sensitive to airborne acidification is considerable, 3% for the rivers in northern Finland and 21% for small forest
lakes. There is general concern among fishers about the effects of acidification. Changes in the fishing waters are attributed
to acidification by 5–10% of the fishers, although in most cases other information about the fishing waters rules out acidification
as an explanation for the changes. Among those who fish in sensitive types of waters, a willingness to mitigate potential
damages was reported by approximately one third of all fishers. Clear differences in the willingness to rehabilitate the fishery
were observed in relation to the importance of fishing as a spare time activity and the distance between the fishing waters
and a home or summer cottage. |
