dc.description.abstract | Water level regulation related to hydroelectric power production and flood prevention
is an important hydro-morphological pressure on many watercourses around the world.
Fouling of fishing nets in autumn during the open water period and in winter under the ice
is a common phenomenon in large Finnish lakes where the water level is regulated. This
fouling of fishing nets can sometimes be so extensive that fishing has to be stopped. Based
on the practical experiences of fishermen, the main cause for the under-ice fouling has
been proposed to be the winter draw-down of water causing low water level and stronger
currents in lakes, but no conclusive relationship between fouling and water level regulation
has yet been demonstrated. Here we show, using long-term winter data from a boreal
lake and short-term netting experiments, that fouling of fishing nets results from increased
water draw-down during winter (January–March). Our results also show that fouling of
fishing nets takes place only if the high water flow rates are accompanied by an intensive
lowering of the water level. We also discuss the relevance of our results to other regulated
lakes with ice cover. | |
