An Integrated Approach to Improve the Knowledge of Ostreid Herpesvirus Type 1 and the Comprehension of Mortality Events in the Pacific Oyster Crassostrea Gigas
In a period of expansion of oysters farming in Italy, the present work aimed to contribute to this challenge approaching several important aspects connected with oyster health management. Firstly, we evidenced the presence of natural populations of C. gigas along the Italian coasts and showed differ...
