Effects of sewage pollution the structure of the community of Ulva lactuca, Enteremorpha linza and rocky macrofauna in Dışliman of Sinop

Abstract

Untreated sewage and domestic wastes from the Sinop outfall enter the Dışliman region. The effect of this on the distribution of Ulva lactuca, Enteromorpha linza and benthic macrofauna and on enviromental parameters was determined. Increases in the growth of opportunistic green algae such as Ulva lactuca and Enteromorpha linzain response to increased nutrient supply in the Dışliman coastal ecosystems in Sinop are reported in the present study. The results of this study show that organic enrichment also increases, with Mytilus galloprovincialis (Mollusca), Erichthonius brasiliensis, Echinogammarus olivii and Amphitoes ramondi, Idotea baltica and Sphaeroma serratum(Crustacea) being the most abundant species.
