Salmo aphelios


Salmo aphelios is a variety of trout, a salmonid fish endemic to Lake Ohrid in Macedonia and Albania in the Balkans.[1][2]

Salmo aphelios is one of four different forms of the Ohrid trout complex within the single lake, along with Salmo balcanicus, Salmo letnica and Salmo lumi. The various trout forms, which have been suggested to be different species,[1] are distinguished by their breeding time and habitat, by which they in practice are thought to be reproductively isolated from each other. Genetic data have not supported their distinction however.[3][4]

Salmo aphelios specifically spawns from May to July near the underwater springs on the eastern shore of the lake, at the Macedonian-Albanian border area. Its flesh is typically of orange colour. Overall the Ohrid trouts are silvery in colour, with black dots. Red dots occur along the lateral line. Salmo aphelios can grow to 40 cm length.[1]
