Use of benthic polychaetes to assess anthropogenic impacts in the southern Saudi Arabian Red Sea Coast
2014
Al Farraj, S.A.
This paper studied the polychaete community structures and their response to anthropogenic impacts in the southerns Saudi Arabian Red Sea Coast. Samples were collected from four stations, i.e. Jazan Port, Fisherman's Port, Corniche North Park Al Qunfudah, along the Southern Arabian Red Sea Coast for benthic polychaetes and environmental variables during July 2012. A total of 75 polychaete taxa were identified from the study area. Spatial trends showed Jazan Port and Fisherman's Port to have low species abundance, richness and diversity compared to a reference site (Al Qunfudah). Species richness, abundance and diversity were intermediate at Corniche North Park. The reference section had the highest species richness, species diversity and evenness with the following dominant polychaete species: Owenia fusiformis, Pista microbalata, Euclymene africana, Maldane sarsi and Syllis gracilis, Capitella capitata, Cirratulus cirratus and Heteromastides bifidus were most abundant at Fisherman's Port and Jazan Port. The study revealed that polychaetes on the southern Saudi Arabian Red Sea Coasts are sensitive to various types of pollution. The data obtained serve as a baseline against which data obtained on subsequent monitoring can be compared. It is recommended that the relevant authorities should carry out a continual assessment on the levels of pollutants in the studied area.
