| Abstract |
The blue jack mackerel, Trachurus picturatus, is a highly consumed pelagic fish in both Mediterranean and Atlantic waters. The present study aims to investigate the digenean parasite species present in fish samples captured off Madeira Island. In 2018, a total of 122 fish samples were collected and examined. Fifteen specimens of Prodistomum polonii were found in the intestine of T. picturatus, indicating low infestation rates. This discovery may be linked to transoceanic connectivity. Negative correlations between parasite abundance and fish size were observed, likely attributable to the dietary preferences of the host. |
