Abstract

Aims: In this study, an individual of H. griseus was caught from the Mersin Bay and this ichthyologic note presents a new female record of H. griseus for Mersin Bay, Mediterranean coast of Turkey. This study aims to contribute to the chronological records of the species in the Mediterranean Sea.

Place and Duration of Study: Yeşilovacık bay is a small bay in the west of Mersin Bay. Yeşilovacık bay which lies at approximately 36°07’n latitude, 33°37’e, longitude and about 143 km Western of in Mersin province, Turkey. Sample: On 19 March 2018 blunthose sixgill shark specimen was measured and then deposited in the Museum of the Systematic, Faculty of Fisheries, University of Mersin.

Methodology: A female specimen of H. griseus with a total length (TL) of 350 cm (400 kg) was captured by a commercial trawl at a depth around of 280 m of the Yeşilovacık Bay (Northeastern Mediterranean Sea), Turkey. Total length was measured to the nearest 1 mm and the weight of the specimen was determined to the nearest kilogram.

Results: Measurements of the specimen are presented and compared with the previous records of H. griseus in the Eastern Mediterranean coast of Turkey (Iskenderun Bay), which are given in Table. The identification was carried out according to the previous report.

Conclusion: To date specific conservation measures are not known for this species for the Northeastern Mediterranean coast of Turkey. Thus, the effect of coastal fishery for sharks should be regularly monitored and protection measures should be taken in this region in order for this shark species to continue their conservation for the next generation.
