Stress on stress response in wild and farmed Mediterranean mussels (Mytilus galloprovincialis Lamarck, 1819) from Sozopol, Black Sea (Bulgaria)

As a continuation of our previous research, wild and farmed mussels from the town of Sozopol, located on the Southern Bulgarian Black Sea coast, were collected to assess and compare the survival rates (stress on stress response, SoS) as a biomarker for the multi-stressor environment. This time we aimed to investigate further if there could be any seasonal differences. Overall, the mussels collected in April had a longer survival time than those collected at the end of January 2024. However, the survival time of wild and farmed mussels had a shorter survival rate in the air than in other studies. The answer to the question “Why is that?” persists.
