Your fish appears to be Psetta Maeotica - in English/French that would be a turbot.
There are few other members hunting in the Black Sea: Bulgaria (Dobs) and probably others on the Turkish side. Maybe they will also contribute to this thread with their catches.
I'm still haven't pulled the trigger on a flat fish for fear of hitting the rocks behind it. They're also not that easy to catch by hand.
Anyway nice tasty catch. Bravo!
