title: The use of enzymatic biomarkers in two marine invertebrates Nereis diversicolor and Patella vulgata for the biomonitoring of Tangier's bay (Morocco).
abstract: The fast increase of anthropogenic activities has led to a continual influx of xenobiotics into the marine ecosystems. Quantifying biochemical parameters in marine invertebrates makes possible the evaluation of pollutants' damaging effect. In fact, to examine the health state of Tangier's bay, we focused on the study of catalase, esterase, acetylcholinesterase and alpha-amylase activities as biomarkers in two species of marine invertebrates Nereis diversicolor (Polychaeta, Nereidae) and Patella vulgata (Mollusca, Prosobranchia), collected from different sites along the Mediterranean coastline of Tangier. Our results showed that these biochemical parameters are disturbed following the level of decreasing environmental quality, and for this reason they are promising in the biomonitoring studies of the Moroccan marine environment.
