Rutilus rutilus caspicus
The Caspian roach (Rutilus caspicus) is a species of roach fish living in the Caspian Sea. The Caspian roach can be distinguished from other roaches by its laterally compressed body, silvery grey iris, rounded snout and grey pectoral pelvic and anal fins with dark margins. The Caspian roach is semi-anadromous and inhabits mostly shallow coastal waters. It enters Volga, Ural, Emba, Terek and Kura drainages for spawning.
The Caspian roach has a typical size of 30–35 cm (maximum published 45 cm) and a weight of 800 g (maximum published 2000 g). It can be distinguished from its congeners in the Caspian Sea by these characteristics:
- usually 42-44 scales along the lateral line
- dorsal fin usually with 9½ branched rays
- anal fin usually with 10½ branched rays
- rounded snout and subterminal mouth
- anal fins and pectoral pelvic are grey with dark margins
Vobla could be considered a raw fish, but, in fact, it is neither raw nor cooked, but rather salt-cured. It is soaked in brine for some days and then is thoroughly air-dried for another two, which in the end denatures the protein, as a form of chemical "cooking".
