dc.description.abstractThe study, which aimed to determine some population parameters of picked dogfish (Squalus acanthias L. 1758) distributed in the Black Sea, was carried out in the five fishing seasons (between 2016 and 2023 years). The sharks draw attention as a bycatch for all fishing gear used in the Black Sea. In the study, total length (cm), weight (g) and sex (female/male) data were obtained from the sharks captured with all fishing gears (demersal trawl, midwater trawl, gillnets purse seine, turbot gillnets, trammel nets and bottom) used in commercial fishing activities in the Black Sea of Türkiye. A total of 576 specimens were collected all fishing gears during the sampling period. Length-weight relationship (LWR) was founded as W=0.0097L2.8521 (R2 =0.9854) for all the picked dogfish. Also, mean total length 48.9±0.707 cm respectively. In addition, the first record of the angular roughshark (Oxynotus centrina, L. 1758) species was given for the Black Sea coasts, which originated in the western Atlantic, was seen in the Mediterranean, Aegean Sea and the Marmara Sea of Türkiye. The shark, which was accidentally caught with a purse seine net, measured as 33.5 cm in total length and weighed 585 g.
