Lake Trout / Brown Trout (Salmo trutta lacustris)

The lake trout (known as "järvitaimen" in Finnish, which refers to the landlocked, lake-dwelling form of brown trout) is one of the most sought-after and beautiful freshwater fish in Finland. Known for its explosive strength and cleverness, it is a dream catch for many. Because wild stocks are critically endangered in Finland, fishing for them is strictly regulated.

Characteristics and Habits

The landlocked brown trout is physically very similar to the sea trout. Its sides are silvery or brownish, covered with black spots, and sometimes red spots (especially in younger specimens or river variants). Lake trout grow in large, deep lakes (such as Saimaa, Päijänne, and Inari) feeding on vendace and smelt, and migrate into connecting rivers and streams to spawn in the autumn.

Fishing

Fishing for lake trout requires skill, patience, and knowledge of the waters. The most popular fishing methods are:

  • Trolling: Trolling with plugs (wobblers) and spoons on open lake waters is the traditional and most effective way to catch large lake trout.
  • Rapids fishing: Wading and casting with fly fishing or spin fishing gear on rivers and rapids is highly popular. Streamers (mimicking baitfish) and small minnow plugs are very effective in current.
  • Spin casting: Casting from a boat near rocky shallows and islands in spring and autumn when the surface water is cold.

Conservation and Regulations

Due to damming of rivers and historical overfishing, wild brown trout populations in Finland are critically endangered. It is vital to follow strict rules:

  • Wild trout (with intact adipose fin) are completely protected in all water bodies south of latitude 64°00’N.
  • Stocked trout (with adipose fin clipped) have a minimum size limit of typically 50 or 60 cm depending on the specific water area. Always check local rules before fishing.

As a Food Fish

Stocked, adipose-clipped trout of legal size make for a premium delicacy. Its reddish, fatty, and flavorful meat is ideal for curing (graavi), smoking, baking in the oven, or grilling over an open fire.
