Salmo trutta

In Finland, salmon trout are found throughout the country, but are not found in every locale because salmon trout flourish best in clear and unpolluted waters. Salmon trout are separated into three ecological species: sea, lake and brook trout. Sea and lake trout migrate, but brook trout have not adopted this pattern of behaviour. When spawned in a river, salmon trout feed on aquatic macroinvertebrates and insects. At the sea and lake stages, fish is their most important food source. In the sea, the most important food sources are Baltic herring and stickleback; in lakes they are vendace, smelt and nine-spined stickleback. Throughout their lives, brook trout feed on insects, basic life forms, and even crustaceans. Salmon trout spawn in the autumn. The most common fishing gear used to catch salmon trout are nets, lures, dry flies, and when at sea, also drum nets.
