Özet
Angular roughshark (Oxynotus centrina) is a rare occurrence and one of the critically endangered species. In our study, some morphometric measurements of angular roughshark individual caught as bycatch with trammel nets was investigated in the Southern coasts of the Marmara Sea, Turkey. The weight of this species, which was caught in these nets, was weighed as 212 gr due to the degradation by parasites. The actual weight before degradation was estimated as 2623 gr from the length-weight relationship formulation. Some morphometric measurements of the species were performed and compared with previous studies. In fisheries, there is a need for all kinds of information about endangered species such as angular rough sharks, which are accidentally caught. Fishing techniques should be developed to prevent these species from being caught in fishing gears, and their survival should be ensured with appropriate protection measures.
