Results of management of oyster spawning stocks and obtaining of their juveniles in artificial conditions
A study of linear and weight growth of Pacific (Crassostrea gigas) and Black Sea (Ostrea edulis) oysters was made in 1992-1993 in three areas of the Black Sea coast of Crimea (Ukraine): 1) in the southern part of the Kerch strait; 2) in the Lake Donuzlav; 3) on the Kara-Dag coast. Oysters were kept...
