Abstract
Subject headings
Close
- Unexpected increasing trends in the concentration of contaminants in European perch (Perca fluviatilis) and in activity of ethoxyresorufin-O-deethylase (EROD) in European perch and eelpout (Zoarces viviparus) have been observed at a Swedish coastal reference site. This study uses data from different sources to investigate plausible explanations. The results showed that a change in diet and an improved overall condition coincide with an increase in mercury in European perch. Furthermore, an increase in several organic contaminants in European perch coincided with the introduction of an invasive deep-burrowing polychaete, which likely contributed to the release of contaminants through bioturbation. The increase in EROD-activity in both species seems to be related to contaminants that reach the fish through the water rather than the diet. The results show that for contaminants that are taken up via the diet, trends in contamination can be opposite for different species of fish in the same area. © 2020
