Value of species
While R. heckelii was not accepted as a valid species by most authors, recent molecular studies strongly support the validity of this species.
Tributaries of Aegean Sea east of Lake Volvi and rivers draining to the northern Black and Azov Seas, entering all rivers in that area.
Reported to decline in population in the 1950s and 1960s. Currently declining but still abundant especially in the Azov Sea.
Habitat: Spends most of year in shallow brackish coastal waters. While at sea, adults are most abundant at 2.5-4 m depth and 2-4 m during summer. Enters freshwater of estuaries, lagoons and lower reaches of large rivers to spawn.
Biology: Semi-anadromous, riverine and lacustrine populations. Anadromous populations starts approaching coasts in August and entering rivers in September, with a peak in October. Ceases migration by end of November and overwinters in main river or estuaries. Spawning migration resumes with breaking up of ice in March (Dnipro). Spawns in April-May. Adults return to estuaries to forage immediately after spawning. Juveniles migrate to estuaries during first summer (August).
In Russia, other countries of the former Soviet Union and parts of Eastern Europe, this and related species of roach are commonly air-dried and salted to create a popular beer snack.
