Whitefish fishing in Sweden

Whitefish (Coregonus lavaretus) is a salmonid that lives in deep, oxygen-rich lakes and along the coast of the Gulf of Bothnia. In Sweden it is a classic table fish, prized for its white, fatty flesh and for the autumn fishery around the spawning grounds. It is caught by bait fishing, ice fishing, fly fishing and trolling alike.

Where to find whitefish

Whitefish occur in the majority of Sweden's larger lakes and along the entire coast from Öresund up to the Torne River. The best-known waters are Vänern, Vättern, Storsjön in Jämtland, Torneträsk and the archipelagos of the Gulf of Bothnia. Along the Norrland coast, whitefish are central to traditional small-scale fishing.

Whitefish favour cold, clear, well-oxygenated water. In deeper lakes they often hold at 10–30 metres through summer, moving into shallower water to spawn in autumn.

Season and best time to fish

There are two prime periods: early summer, when whitefish move shallow and take hatching insects, and October–November when the spawning migration begins. In winter they are jigged through the ice at 8–20 metres in clear lakes.

Closed seasons and minimum sizes vary between counties — always check the county administrative board's rules and svenskafiskeregler.se before you fish.

Methods and baits

Bait fishing with maggot or sweetcorn hard on the bottom is the classic approach, and is especially effective from a jetty or boat along a drop-off. Use fine line of 0.14–0.18 mm and small hooks in sizes 10–14.

Fly fishing for whitefish works well during surface activity — small nymphs, midge pupae and emergers in sizes 14–18. Ice jigging with a small jig and maggot is standard in winter. Trolling with small crankbaits, or a flasher and fly, is productive in Vänern and Vättern.
