Arctic charSalvelinus alpinus In clear watered streams and lakes in northern Lapland lives a slender and beautiful salmonoid fish called arctic char. Arctic char also reside in the waters of Vuoksi, although their habitat has shrunk. Arctic char are separated into two forms based on their colouring and migrating habits, large arctic char and small arctic char. It is unclear whether the two forms are subspecies or local forms of the same species. The arctic char is a tasty and highly appreciated salmonoid fish, which is best enjoyed fresh, as it keeps poorly. However, while fishing for it, one should remember that it is on Finland’s endangered species list.  
Brook troutSalvelinus fontinalis Trout are treasured fish of Finland’s inland waters. They prefer clean, cool, oxygen-rich bodies of water and reside all over Finland. The trout has a unique behavioural trait that sets it apart from lake salmon; it not only swims upstream but also downstream to spawn. Large trout may weigh more than 15 kilograms and be over one meter long. Trout consume insects, crustaceans and other fish. 
GraylingThymallus thymallus Silvery grayling live in the lakes of North Finland and the coastal areas of the Gulf of Bothnia, but migrate into streams during springtime. They have a tall brush-like dorsal fin that particularly males like to display proudly during territorial disputes. The grayling requires cool and oxygen-rich water. Its diet is similar to that of trout and consists of bottom-living mollusk, insect larvae and crustaceans. It is viewed as a serious competitor to trout. The grayling can grow up to half a meter in length and weigh one kilogram; like trout, it is a savoury and highly appreciated food fish. 
MinnowPhoxinus phoxinus Up to 10 centimeters in length, the minnow swims happily in shore waters and is a familiar sight to many. During summer months, it enjoys swimming in schools, but during the winter, it seeks seclusion in deeper waters. The minnow is abundant in Finland's inland waters, lakes, streams and coastal areas. Despite its abundance, it has no economic value. Nevertheless as an aquarium and research fish, it is interesting and easy to take care of. The minnow's diet consists of water fleas, insect larvae, small bottom-dwelling crustaceans and gastropods. 
SalmonSalmo salar Salmon is the king of Finnish fish, at least in regard to its size: fully grown it can weigh over 30 kilograms! However, the history of the Finnish salmon is a sad one. At the beginning of the last century there were 18 salmon rivers, now there are only a few rivers left for them spawn in Tornio, Simo, Teno and Naatamo. Pollution, dams and other factors have eradicated important breeding areas for salmon. Due to the pollution, female salmon must be planted in certain areas to encourage reproduction. Salmon are sea fish and only migrate to rivers to breed. Their offspring usually return to the sea at the age of two. Salmon are ravenous beasts that prey on, among other things, herring and large crustaceans. A subspecies, called the lake Salmon, inhabits the waters of Vuoksi. |
