Abstract :Oxynotus centrina is considered a rare or uncommon shark species throughout its distribution range. Because of this reason, it is one of the 46 uncommon elasmobranchs in the Mediterranean Sea, which requires filling the knowledge gaps, such as length-weight relations. Based on the analysis of 34 angular rough sharks, the length-weight relations insert ignore into journalissuearticles values(LWR); of males, females and combined sexes of O. centrina were described as W = 0.216L2.686, W = 0.134L3.041 and W=0.102L3.173, respectively. Total lengths insert ignore into journalissuearticles values(TL); of females and combined sexes were strongly correlated with total weights insert ignore into journalissuearticles values(TW);; while TL of males was moderately correlated with TW. The b values of LWRs of females and combined sexes insert ignore into journalissuearticles values(3.041 and 3.173, respectively); were not significantly different from 3.0 insert ignore into journalissuearticles values(t-test, p>0.10); and indicated positive allometric growth for the examined TL and TW range of O. centrina in the Mediterranean Sea.
