The streams have long been home to several species of trout, but stocking of the lakes has increased their numbers there along with mountain whitefish and grayling.
The Coeur d’Alene lived in areas of abundance that included trout, salmon, and whitefish.
He wrote several articles about the Swiss freshwater fish species from the genus Coregonus.
Traditionally, carp, pike, mullet, or whitefish were used to make gefilte fish, but more recently other fish with white flesh such as Nile Perch have been used, and there is a pink variation using salmon.
Because of its location on Śniardwy, the fishery of Nikolaiken ensured continued prosperity; the whitefish of the region were especially popular throughout East Prussia.
Coregonus | Coregonus vandesius | Coregonus trybomi | Coregonus albula |
Coregonus albula generally breeds in the autumn, but in several North European lakes distinct spring-spawning populations of vendace exist, some of which have been described as separate species: in Sweden, as Coregonus trybomi, and in two lakes of northern Germany, as Coregonus fontanae and Coregonus lucinensis.
It was described as Coregonus annectens confusus by Victor Fatio in 1885 from syntypes which have been lost in 1902.
The lake is believed to be the last remaining native habitat of the vendace (Coregonus vandesius) fish from the 4 originally known sites: Bassenthwaite Lake and Derwent Water in the Lake District and the Castle Loch & Mill Loch in Lochmaben.
The distribution of Coregonus pidschian is in the Arctic basin, ranging from Northern Norway and Finland across the Russian coast to Alaska and up to the Mackenzie River drainage in North-West Canada.
48 forms (species and infraspecific taxa) of fish have been encountered in the lake, including roach, carp bream, zander, European perch, ruffe, endemic variety of smelt, two varieties of Coregonus albula (vendace), eight varieties of Coregonus lavaretus, a number of other Salmonidae as well as, albeit rarely, endangered European sea sturgeon.
The powan (Coregonus clupeoides) is a kind of freshwater whitefish endemic to two lochs in Scotland, Loch Lomond and Loch Eck.
The fish is endangered, because various competitors were introduced into the lake during the Soviet period, including common whitefish (Coregonus lavaretus) from Lake Ladoga, goldfish (Carassius auratus) and narrow-clawed crayfish (Astacus leptodactylus); and because of lake level change.
