Özet

Savalia savaglia is one of the highly important key species forming biodiversity hotspots in marine environment. The Mediterranean-originated coral facies may rarely constitute some species-rich ecosystems far from their native waters. The present study deals with the four uncommon reef sites of S. savaglia in the Turkish Seas. According to the pre-assessment of assemblages from several rocky and wreck sites in the Turkish Straits System, there have discovered some large individuals of S. savaglia reaching a maximum diameter of 117 cm in height in the Çanakkale Strait (42 m, trunk circumference: 13,2cm) and 96.4 cm in width in Marmara Sea (Avsa-Cinarli region, Marmara Island, 38-47 m) with a maximum basal length of 26.4 cm and 15.5, respectively. In a new project conducted in 2023, 80 benthic invertebrate species were detected around the surrounding area of species in the Marmara Sea, two of which (Phoronida, Porifera) are new record for the eastern Mediterranean Sea from the region. In several sites, the community of Neopycnodonte cochlear was the most structural facies around S. savalia colonies. Additionally, there have been observed an ingulfment situation on separate healthy colonies of Paramuricea clavata at depths between 38-44 meter on the wreck sites. With the present work, the occurrence of colonies of species in the Aegean Sea, was recorded for the first time at mesophotic depths on an offshore rocky bank off Babakale-Assos. In addition to that, a recent severe impact of seine nets recorded recently is also given from a monitored area for the first time. Although Marmara Island is a unique home for some healthy gorgonian forests, there is still no conservation action for a specific coral protection in the area. Due to ongoing fishing activities, illegal catch and anchoring, the present study aims to show the necessity of a coral-based marine protected area in the site, improving the lack of knowledge, focusing the key benefits of S. savaglia at local level and introducing the natural value for other marine life.
