Öz

Angular rough shark is a rare occurrence and one of the critically endangered species. In this study, angular rough shark 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 measured as 212 gr due to the degradation by parasites. The actual weight before degradation was determined as 2623 gr from the length-weight relationship formulation. Morphometric measurements of the species were performed and compared with previous studies. As a result, the population structure and biology of critically endangered species, such as limited information about angular rough shark as bycatch in fisheries should be investigated. Fishing methods will prevent catching angular rough sharks are improved and their survival should be ensured through appropriate protective measures.

Marmara Denizi'nde Fanyalı Uzatma Ağlarına Yakalanan Kritik Tehlike Altındaki Domuz Köpek Balığının (Oxynotus centrina (Linnaeus, 1758) Bazı Morfometrik Özellikleri

Domuz köpek balığı, nadir bulunan ve kritik yok olma tehlikesi altında bir türdür. Bu çalışmada Marmara Denizi’nin güney kıyılarında fanyalı uzatma ağları ile tesadüfi olarak yakalanan domuz köpek balığı incelenmiştir. Ağlara yakalanan türe parazitik canlıların zarar vermesi nedeniyle ağırlığı 212 gr ölçülmüştür. Bozulmadan önceki gerçek ağırlığının ise boy-ağırlık ilişkisi formülasyonuna göre 2623 gr olduğu belirlenmiştir. Türün morfometrik ölçümleri gerçekleştirilerek, önceki çalışmalar ile karşılaştırılmıştır. Sonuç olarak, balıkçılıkta tesadüfi olarak avlanan, hakkında az bilgi bulunan yok olma tehlikesi altındaki domuz köpek balığı gibi türlerin popülasyon yapısı ve biyolojileri araştırılmalıdır. Bu türlerin ağlara yakalanmasının önüne geçecek avlama teknikleri geliştirilerek, uygun koruma önlemleri ile hayatta kalmaları sağlanmalıdır.
