Description of the macrobenthic population in the Gulf of Arzew in northwestern Algeria.
This present research is dealing with the study of the benthic community in the Arzew gulf and permits to give an overview on the MacroBenthos encountered in this area, which seems to be more or less threatened by the Arzew's industrial area pollution. The samples were picked up in 46 several stations with deeps going from 16-96 m, using the Aberdeen Benne, where two hits were needed each station. A sediment undersample was used in the granulometric study. The species identification and the faunistical analysis show, in one hand, the main pollution indicator characteristic species and in another hand the principal dominant ecological stocks. Concerning the data processing, the TWINSPAN (Two Way INdicator SPecies of ANalysis) and the AFC (Analyse Factorielle des Correspondances) based upon the abundance of every species give the same results offering the stations and the species gatherings and this according to their existing affinities and their ecological preferences related to the gulf seabed sedimentary cover.
