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.

Lake Geneva fish at the heart of local gastronomy

The fish of Lake Geneva occupy a place of choice in the regional gastronomy.

The perch fillets are undoubtedly the star of the menu. They are usually served meunière style, accompanied by chips and a homemade tartar sauce. Arctic char, on the other hand, is often served poached or grilled, and is often enhanced by delicate sauces that bring out its fine flesh.

Less well known but just as tasty, the féra is also an emblematic fish of Lake Geneva. Smoked, it is a delight as an aperitif. Grilled, it delights the taste buds of connoisseurs.

During our travels around the lake, we had the opportunity to sample these culinary marvels. I particularly remember a meal in Yvoire, a charming medieval village, where the freshness of the fish and the skill of the chef left a lasting impression.

The gastronomy of Lake Geneva is not limited to noble fish. Gudgeon, for example, can be eaten fried, and pike in quenelles. This culinary diversity reflects the richness of the lake's ecosystem and contributes to the region's cultural identity.

When you look for fish in Lake Geneva, you soon realise that the lake is a treasure trove for anglers and gourmets alike. Its exceptional diversity of fish species, from majestic Arctic char to discreet gudgeon and emblematic perch, provides an exciting playground for anglers and an inexhaustible source of inspiration for chefs. Preserving this richness is our collective duty!
