Impact Of Environmental Stress On Metabolism Of Perinereis Cultrifera

The aim of this study was to investigate marine environmental quality of Skikda coast, which has been subjected for a long time to large amounts of industrial effluents. We have assessed the impact of pollution on a keystone species of benthic communities Perinereis cultrifera using changes in biochemical contents of proteins, carbohydrates, and lipids, monthly determined in oocytes; thus worms were sampled at two study sites Skikda (polluted) and El-Kala (comparatively clean).Energy reserves variation levels were similar for both populations, although concentrations were found higher in females sampled from El-Kala, suggesting a better physiological status.
