Fishing on Lake Geneva: a major challenge

Lake Geneva's wealth of fish stocks is a major asset for the region, but it also faces some major challenges. Visit professional fishing on the lake is going through a difficult period, marked by an ageing fishing population and economic difficulties. What's more, some fish populations are in worrying decline.

Faced with these challenges, measures to sustainable management fisheries resources are put in place. Spawning periods are strictly observed to allow species to reproduce. Fishing quotas are also introduced to preserve the balance of the lake ecosystem.

As responsible fishermen, we are particularly sensitive to these issues. We strongly encourage the practice of respectful fishing and the release of the most important specimens to ensure the sustainability of populations.

The preserving biodiversity of Lake Geneva is everybody's business. Professional fishermen, amateurs and local authorities are working, or trying to work, hand in hand to guarantee a sustainable future for this exceptional natural heritage.
