Abstract :Some population features insert ignore into journalissuearticles values(length, weight, LWR, sex ratio and condition factor); were determined for tub gurnard insert ignore into journalissuearticles values(Chelidonichthys lucerna L. 1758); distributed in the Black Sea coast of Türkiye in the study. The study was conducted between 2018 and 2021 fishing seasons. Fish samples were obtained from the commercial fisheries insert ignore into journalissuearticles values(demersal trawls and set nets); in the region. Mean, maximum and minimum total length were calculated as 38.9±0.99 cm, 73.8 cm and 13.4 cm respectively. Length-weight relationship insert ignore into journalissuearticles values(LWR); of examined fishes was founded as W=0.0112L2.9425 for all individuals. The “b” parameter was defined as negative allometry growth for females insert ignore into journalissuearticles values(2.9345);, isometry growth for males insert ignore into journalissuearticles values(2.9535);. Fulton’s condition factor were calculated as 0.926±0.009 for all individuals. The calculated sex ratio was 1 female: 0.67 male in the examined fishes.
