Bonamia exitiosa in European Flat Oyster ( Ostrea edulis ) on the Croatian Adriatic Coast from 2016 to 2020
The annual production of European flat oysters ( Ostrea edulis ) in Croatia is about 50 to 65 tons, and it has a long tradition. All Croatian oyster farms are subjected to the national surveillance program aiming to detect the presence of Bonamia ostreae and Marteilia refringens according to the Cou...
