Investigation of harmful algae in İzmir Bay for the 30 years

Abstract



Marine pollution, which has been seen for the recent years in cities with a coast that industrializes day by day, was also seen in İzmir, the third most populous city of Turkey. After the destruction of Ragıp Paşa jetty and especially the completion of the Grand Canal Project, the improvement in the gulf is increasing day by day. In İzmir Bay, which is one of the most fertile areas of the Aegean Sea, excessive algae growth is occasionally observed. In this study, 360 quantitative and 1080 qualitative samples were obtained during the monitoring projects carried out jointly by İzmir Metropolitan Municipality, Dokuz Eylül University Marine Sciences and Technology Institute and Ege University Faculty of Fisheries between 1990-2016 were examined. The distribution of the 2 dominant major classes Dinophyceae and Bacillariophyceae were investigated. In addition to the species that produce toxins such as DSP, ASP and PSP into the marine environment, species that do not contain any toxins but cause adverse conditions in the environment by mass-formation were investigated.

This study was carried out by examining the plankton samples obtained from the bay monitoring projects organized by the Izmir Metropolitan Municipality and the Institute of Marine Sciences and Technology of Dokuz Eylul University on a seasonal basis every year between 1990-2016. The author participated in the expeditions under the Expedition coordinator Prof.Dr. Bülent CİHANGİR and Res. Ass. Dr. Erkan DEMİRKURT and collected quality plankton samples and bottle quantity samples carried out sedimentations, microscope studies, entered the counting results and species lists into the spreadsheet software, and presented them to Prof.Dr. Tufan KORAY approved and carried out statistical work results seasonally 4 times a year as Spring, Summer, Autumn, and Winter. Phytoplankton section of the projects. Res.Ass. Dr. Fatma ÇOLAK SABANCI contributed to the identification of species with a microscope (1997-2008) and sample collection (1998-2000). The faculty’s project coordinators, Prof.Dr. Mesut ÖNEN (1990-2004) and Assist. Fevzi KIRKIM (2004-2016) added all the other sections into the project and transferred them to Dokuz Eylül University Marine Sciences and Technology Institute project managers (Prof. Dr. Hüseyin Avni BENLİ, Prof. Dr. Bülent CİHANGİR, and Prof. Dr. Filiz KÜÇÜKSEZGİN). Ege University Faculty of Fisheries Department of Hydrobiology carried out the storage and evaluation of the plankton samples collected from the joint projects of Izmir Metropolitan Municipality and Dokuz Eylul University Marine Sciences and Technology Institute. I would like to thank all the staff above who contributed to the realization of this work.
