Thymallus ligericus, the Loire grayling, is a European freshwater fish species in the salmon family Salmonidae. The species is endemic to the upper Loire drainage in France , where it lives in medium to large foothill, canyon and plateau rivers of the mountainous regions.[1]
The Loire grayling was separated as a species distinct from the more widespread European grayling, Thymallus thymallus, in 2019. It is morphologically distinguished from that species by a more elongated body, by its pointed snout (with a straight or convex snout profile vs a concave profile of T. thymallus), a more inferior mouth, a high number of black dots on the sides, a shorter head and a shorter horizontal eye diameter.[1] It can also be distinguished by molecular characters.[1][2]
