In the open waters of V鋘ern, the most common fish is the vendace ( " Coregonus albula " ), also most prominently in Dalbosj鰊, with 200 300 fish per hectare.
Types of fish in the lake waters include " Coregonus albula ", common bream, European perch, Northern pike, zander, silver bream, common rudd, common roach and common bleak.
"Coregonus sardinella " is closely related to the European cisco or vendace " Coregonus albula ", and also is close to the Siberian peled whitefish " C . peled ".
"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 ".
