|Abstract:||The effect of highly turbid seawater on the distribution, biomass and species diversity of intertidal macrofauna was studied in Gopnath, Mahuva and Veraval coasts during October 1998 and June 1999. The concentration of total suspended solids and turbidity were very high at Gopnath (518-583 mg/l and 632-713 NTU respectively) and Mahuva (328-412 mg/l and 566- 621 NTU respectively) during the period of study. The species diversity was minimum at Gopnath (1.14) and maximum at Mahuva (1.86). However, the biomass of benthic organisms was maximum at Veraval and the values were 2.03-5.82 and 2.02-2.03 times more as compared to Gopnath and Mahuva respectively. The data for similarity index revealed that Gopnath and Mahuva were more similar during October and June than Gopnath, Veraval and Mahuva and Veraval. Astraea semicostata, Clibanarius clibanarius, Crassostrea cuculata and Littorina scabra recorded only from Gopnath and Mahuva where seawater was highly turbid. The results indicate that these species could be cultivated in the coastal areas where seawater is significantly turbid.|
