Knowra Coregonus Coregonus Coregonus is a genus of salmon-family fishes that includes whitefishes and ciscoes. Its species inhabit freshwater lakes and rivers, and some migrate between fresh water and the sea.
Salmonidae : Salmonidae is a family of ray-finned fishes that includes salmon, trout, char, whitefishes, and graylings. Coregonus is one branch of this fish family.
Lake whitefish : Lake whitefish is a North American freshwater fish, Coregonus clupeaformis, valued in commercial and subsistence fisheries. It is a widespread, commercially important member of the genus.
Zooplankton : Zooplankton is the animal component of plankton, including small crustaceans and drifting larvae. Many Coregonus species filter or pick these animals from the water column.
Great Lakes fishery : The Great Lakes fishery is the commercial, recreational, and subsistence harvest of fish in the Laurentian Great Lakes. Lake whitefish and ciscoes have long supported fisheries in this region.
Salmoniformes : Salmoniformes is an order of ray-finned fishes that includes the salmon family, Salmonidae. This broader classification places Coregonus among related fish lineages.
European whitefish : European whitefish is a name for Coregonus lavaretus, a freshwater fish with populations across northern Europe. Its populations illustrate the genus’s extensive variation across lakes.
Benthic zone : The benthic zone is the ecological region at the bottom of a body of water. Bottom-feeding whitefishes forage in this habitat for invertebrates.
Sea lamprey : Sea lamprey is a parasitic jawless fish native to the Atlantic basin and invasive in the Great Lakes. Its spread contributed to major changes in Great Lakes fish communities.
Pharyngeal teeth : Pharyngeal teeth are teeth on bones in the throat that help some fishes grasp or process food. Their structure helps distinguish coregonine fishes from other salmonids.
Vendace : Vendace, Coregonus albula, is a small European whitefish that feeds largely on zooplankton. This small-bodied species represents a plankton-feeding form of Coregonus.
