Abstract

The main goal of this study is monitoring of diversification of some algae and macro invertebrates attached to marine sea cage farms (floating tubes, net, ropes) and also carried out from January 2015 to February 2020 at in the Gülbahçe-Izmir Bay. Sampling of macro invertebrates and algae were performed by scuba divers and recorded underwater camera (Gopro black edition). As a result, totaly 15 macro invertebrata species were determined. 10 species belongs to bivalvia, 3 species belongs to crustacea and 2 species belongs to Echinodermata and dominated by some economical Mytilus galloprovincialis, and Balanus sp. Additionally, it was determined that Ostrea edulis, Pinctata radiata Paracentrotus lividus, and Modiolus barbatus has economical value among these species. Totaly 5 algae species were determined, Ceramium sp belons to Rhodophyta, Ulathrix sp belongs to Ochrophyta, Enteromorpha comprezza, Ulva rigida and Ulva lactuca belongs to Chlorophyta. It is concluded that marine sea cage units are artificial habitats in the marine ecosystem for providing of  habitat and enhancement of natural stock for fish/other aquatic organisms.
