Abstract :Age, growth parameters and food of Pterois volitans insert ignore into journalissuearticles values(Linnaeus, 1758); Red lionfish were studied. A total of 254 lion fishes insert ignore into journalissuearticles values(P. volitans and Pterois miles); were collected from commercial drift net, angling fisheries and diving with hand net southern coast of the Iskenderun Bay between March 2018 and March 2019. 29.53% of sample was P. volitans. Age was determined by reading whole sagittal otoliths. Fish ranged from 14.2 to 35.3 cm in total length, which corresponded to fish between 1 to 7 years old. The sex ratio insert ignore into journalissuearticles values(1:1.07); was biased toward males insert ignore into journalissuearticles values(P<0.05);. The length–weight relationships were W=0,0042×L3.3514 insert ignore into journalissuearticles values(R²=0,92); and W=0,0108×L3.0423 insert ignore into journalissuearticles values(R²=0,94); for females and males, respectively. Growth parameters were estimated using the standard von Bertalanffy growth model insert ignore into journalissuearticles values(K=0.1507, 64, L∞=47.58 cm and to =-2.0506 for combined sexes. The diet was composed of fishes and crustaceans.
