The powan (Coregonus clupeoides) is a kind of freshwater whitefish endemic to two lochs in Scotland, Loch Lomond and Loch Eck.[1] It has been successfully introduced in two other sites, Loch Sloy and the Carron Valley Reservoir.[3]
Powan populations are relatively healthy,[1] but may have been negatively impacted by the introduced ruffe, which eats powan eggs and fry. As a conservation action, an attempt to establish populations in four additional lochs has been undertaken.[4][5]
The taxonomic status of the British whitefish populations, including powan, is a matter of debate. Currently the Scottish powan, along with the Welsh gwyniad known from a single lake, and four similar populations in England known as schelly, are generally considered belonging to the widespread Eurasian common whitefish (Coregonus lavaretus).[3][6] This accords with the close genetic similarity among these units,[7] and the absence of clear morphological differences between them.[8] FishBase and the IUCN continue to recognize the Scottish powan as a distinct species, Coregonus clupeoides.[1][9]
