Fish in Swedish waters include those found in fresh waters (lakes and streams) and salt water. There are about 140 species native and common in Sweden, and another 90 species which are sporadic, not established or extinct. Some of the most common fish found and caught in Sweden are pike, perch, zander, trout and salmon.
The following are some types of Swedish fish:
•Pike belongs to the Esox family, and it is the only member of this family found in Europe. This fish is also known as Epox or northern Pike. It is found to be thriving in all the lakes in Sweden, yet in the most northern lakes it is more sporadic. This is the largest fresh water fish in the country. Officially of all the Swedish fish found in fresh waters, the biggest was a pike weighing 19kgs.
•The strength and size of salmon is a great challenge for sports fishermen. Salmon are often caught for sport, yet also are an important source of food. Salmon has become extinct in some waterways in Sweden, due to being a sensitive fish to power stations and other changes to the natural streams. Artificial cultivation has been done with this fish, yet does carry the risk of disease development which is dangerous to the salmon population.
•The European perch is considered the most popular of all local fresh water fish. It is a common fish to be found, except in the waterways of the mountain regions north of the country.
•The largest zander caught was just over 12kgs and this common fish is popular among fishermen as it is tasty.
•Of the various types of catfish, it is the species known as the Wels catfish that is found in Sweden. This is a large fresh water fish and is confirmed to be found in the streams of Helgeån, Emån and Båven.
•Brown trout are divided into Marine trout, Stream trout and Lake trout (due to environmental variations). They are common in fresh water yet vulnerable to decreasing numbers like the salmon.
•The Basking shark is the largest fish found in Sweden’s waters (including Nordic waters). It is sometimes noticed along the west coast of the country and is classified as endangered. The second largest fish in Swedish waters is the Greenland shark.
•The Atlantic cod is one of the most important food fish. The Baltic cod has especially suffered from a great deal of fishing, which has led to it being classed as endangered. The haddock belong to the same family as do the Atlantic cod;it also is caught mainly to supply food and its population numbers are known to have significantly decreased.
•The herring are among the most important food fish. Since the Middle Ages, herring have had a great effect on supporting the economy as a food source. Its impact on the economy may be the most important of all the fish. The herring are named locally Sill or Strömming, depending on location of being fished (caught) from. Fermented herring is considered a delicacy by some and generally tinned herring is a common component of Swedish cuisine.
•The European eel has suffered a great deal from overfishing and pollution. It has been classified as critically endangered. This is a popular food source, especially in southern Sweden.
