Mucus Secretion Responses to Various Sublethal Copper (II) Concentrations in the Mussel Perna perna

Authors: Kamleshan Pillay

Abstract:

The purpose of this study was to evaluate the use of mucus production as a biomarker. This was done by exposing the mussel Perna perna to various sublethal concentrations of Cu. Mussels are effective as a bioindicator species as they accumulate Cu in their tissues. Differences in mucus production rates were evaluated at different Cu concentrations. The findings of this study indicate that increasing Cu concentrations had a significant effect on the mucus production rates over a 24 hour exposure. There were also significant differences between the mucus production rates at different Cu concentrations (p < 0.05). Thus, mucus is an essential detoxification mechanism.

Keywords: Copper, Mucus, Depuration, Perna perna.
