Rivers draining to northern Black Sea. Lipkovska stream in upper Vardar drainage (Macedonia). Anatolian populations have recently been show to be two distinct species, Salmo coruhensis and S. rizeensis, reducing the distribution area of the species.
Habitat and Ecology
At sea, along coasts at depths of up to 50 m. Migrates to hill streams. Resident part of populations in streams and uppermost reaches with fast current, cold clear water and stone or gravel bottom. Spawns in upper reaches with fast current.
Anadromous, lacustrine and resident ecotypes. Spawns in October-January. Parrs spend 2-4 years in rivers and streams, then smoltify and migrate to sea or mature in freshwater. Spends 2-4 years at sea. Anadromous individuals return to rivers in April-May and again in October-November. Eggs hatch in 6-8 weeks. Parrs and resident adults feed on a wide variety of aquatic and terrestrial invertebrates. Anadromous and large lacustrine individuals feed mainly on fish and large crustaceans. Anadromous individuals feed while in rivers.
IUCN Red List Assessment
Red List Category
Red List Criteria
Because the species has been impacted by the construction of dams (mostly more than three generations ago), it has now stabilised at a lower level and, therefore, does not qualify for the threatened or Near Threatened category. The anadromous ecotype is very rare in Europe now. Because of dams, most returning adults are unable to reach spawning sites. The resident populations are less impacted by the dams.
European Union 27 = LC. Same rationale as above.

Black Sea salmon
The Black Sea salmon (Salmo labrax) is a fairly small species of salmon or trout, at about 20 inches (510 mm) long on average and rarely reaching over 30 in (760 mm). It inhabits the northern Black Sea coasts and inflowing rivers. There are anadromous, lacustrine and resident river populations. This fish is a close relative of the brown trout. While it is the only only native species of Salmo present in the northern Black Sea basin, it may hybridize with (introduced) brown trout in the major rivers. Sea-run populations are currently at low numbers, but the resident river stocks are doing well.
