Coregonus lavaretus

summary 4

Coregonus lavaretus, known as the Powan in Scotland is one of the rarest Scottish freshwater fish. According to Scottish Natural Heritage, natural populations occur in only two lochs, Loch Lomond and Loch Eck. fish from these populations have been transplanted to other lochs in order to establish populations as part of a conservation effort. the Powan is under threat from the Ruffe, an invasive species which eats Powan eggs. the Powan is on the IUCN red list of threatened species and is a protected species under British law.
