Main outcome of study (acc. to author)

For all species investigated no effect on survival rate could be observed. Blue mussel were further examined for condition index (CI), in the meaning of flesh weight as a percentage of total weight. Additionally the gonad index (GI) of the mussel was determined by grading the tissue in different stages. No significant changes in CI and GI were found either.
