📖 Overview

Adults inhabit shallow coastal waters as well as freshwater regions of rivers . Very common in the rivers discharging into Peter the Great Bay; enter freshwater. Juveniles spend their first year in freshwater then migrate to sea to breed . Large concentrations of fry-of-the-year measuring 3.1-6.2 cm in the mouths of rivers in August. Length in the Black Sea is usually 20-30 cm but may reach 43 cm; length in the Atlantic Ocean may reach 50 cm . Omnivorous . Oviparous, eggs are pelagic and non-adhesive . Alien Invasive: In Azov Sea, it is now the most abundant mugilid species. Along shores of Black Sea, its expansion corresponds to a sharp decline of native species of Mugilidae, which it apparently replaces .
