Some population features (length, weight, LWR, sex ratio and condition factor) were determined for tub gurnard (Chelidonichthys lucernus 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 (demersal trawls and set nets) in the region. A total of 154.788 kg (203 specimens) tub gurnard was captured from all fishing seasons. 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 (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 (2.9345), isometry growth for males (2.9535). Fulton’s condition factor were calculated as 0.926±0.009 for all individuals. The observed sex ratio was 1 female: 0.67 male in the examined fishes. |
