Abstract

In this study, two individuals of the angular rough shark Oxynotus centrina as discard by a commercial trawler were examined. Gravid female of this species was recorded for the first time from the northeastern Mediterranean. Occurrence of a gravid female and adult male of O. centrina in the northeastern Mediterranean Sea strongly indicates that there is a nursery area in this region, and mating probably occurs.
