Polychaetes are indicators to assess marine pollution. The aim of this study was to examine the effects of brine discharge over softbottom polychaete community in Chabahar Bay. Forty-two sediment samples were collected from seven stations in pre summer monsoon （April 2011） and post winter monsoon （October 2011） using Van Veen grab sampler. Changes in the polychaeta data assemblages were analyzed using univariate and multivariate techniques. Thirty-one polychaete species were identified with the highest abundance in station 6 in pre monsoon period and the lowest abundance in station 1 in pre monsoon. The results showed that the abundance, richness and diversity indices were decreased in the stations near the discharges area comparing to control stations far from the brine discharges zone. CCA （Canonical correspondence analysis） showed that salinity and temperature have influenced the community structure of polychaeta.展开更多
