Pojava plavog dugmeta Porpita porpita (Linnaeus, 1758) zaljev Iskenderun, sjeveroistočna mediteranska obala Turske
The blue button Porpita porpita (Linnaeus, 1758) was observed for the first time in July 2018 in the Iskenderun Bay, Northeastern Mediterranean coast of Turkey. This is the third record of this species for Turkish marine waters, while it is the first record for Iskenderun bay. The presence of P. porpita in the northeastern Mediterranean coast of Turkey shows its extension from northwestern Mediterranean coast (Antalya Bay) of Turkey.Plavo dugme Porpita porpita (Linnaeus, 1758.) prvi je put primijećen u srpnju 2018. u zaljevu Iskenderun, sjeveroistočna obala Mediterana u Turskoj. Ovo je treći zapis ove vrste za tursko more, a prvi je zabilježeni nalaz za zaljev Iskenderun. Prisutnost P. porpita na sjeveroistočnoj mediteranskoj obali Turske pokazuje njezino proširenje od sjeverozapadne mediteranske obale (zaljev Antalya) u Turskoj
A Checklist of the Non-indigenous Fishes in Turkish Marine Waters
A checklist of non-indigenous marine fishes including bony, cartilaginous and jawless distributed along the Turkish Marine Waters was for the first time generated in the present study. The number of records of non-indigenous fish species found in Turkish marine waters were 101 of which 89 bony, 11 cartilaginous and 1 jawless. In terms of occurrence of non-indigenous fish species in the surrounding Turkish marine waters, the Mediterranean coast has the highest diversity (92 species), followed by the Aegean Sea (50 species), the Marmara Sea (11 species) and the Black Sea (2 species). The Indo-Pacific origin of the non-indigenous fish species is represented with 73 species while the Atlantic origin of the non-indigenous species is represented with 22 species. Only first occurrence of a species in the Mediterranean, Aegean, Marmara and Black Sea Coasts of Turkey is given with its literature in the list
Environmental DNA for Detection of Endangered Grouper Species (Epinephelus spp.)
Marine ecosystems nestle species or populations known to be threatened due to human overexploitation. Reliable detection and monitoring of threatened organisms is crucial for data-driven conservation actions. Furthermore, misidentification of species represents a major problem. Here, we investigate the potential of using metabarcoding of environmental DNA (eDNA) obtained directly from seawater samples to detect endangered grouper species (Epinephelus spp.). Cytochrome c oxidase subunit I (COI) fragment of mtDNA was used to detect groupers species in the Mediterranean Coasts. We conducted eDNA sampling at sites by underwater diving across the range of the Grouper species habitats in Northeastern Mediterranean (Antalya-Kas Region and Iskenderun Bay). eDNA was isolated from 2 liter seawater samples which were vacuum-filtered onto 0.45-mm membrane filters. Filters were then folded inwards, placed in 2 ml tubes and stored at -20 oC until DNA extraction, which took place within 24 hours. DNA was extracted from the water sample filters using the DNeasy Blood and Tissue Kit (Qiagen, USA). Manufacturer’s protocols were used during all steps. PCR amplification of eDNA samples were done using selective primers of COI region of mitochondrial DNA, and next-generation DNA sequencing of PCR application was conducted. For the successfully obtained COI sequences, maximum matching rates were revealed as 80% for Epinephelus marginatus, 78,95% for Epinephelus aeneus, 73,48% for Epinephelus costae, 63,45% for Epinephelus caninus, 60,12% for Mycteroperca rubra and 57,12% for Hyporthodus haifensis. Despite the methodological challenges inherent in eDNA analysis, the results demonstrated that eDNA method may be proved to step towards a new beginning to detect and monitor endangered grouper species
First Record Marbled Shrimp Saron marmoratus (Olivier, 1811) from Turkish Marine Waters
During the Scuba survey at the Çevlik coast area of the southeastern side of the Iskenderun Bay on February 3, 2018. One male specimen of marbled shrimp Saron marmoratus was collected by scoop net at a depth of 15 m. With the present study, S. marmoratus is the first time reported from Turkish marine waters. S. marmoratus probably be entered the Mediterranean through the Suez Canal
