Abstract:

The study was carried out between 01 September 2021 and 15 April 2022 in the Western Black Sea coasts. Tub gurnard (Chelidonichthys lucerna L., 1758) were examined in the commercial fishery. A total of 28.885 kg tub gurnard was caught during the study period. Total length and weight of 54 tub gurnard individuals were measured. Minimum, maximum and average total lengths were calculated as 15.2 cm, 55.5 cm and 25.6±0.95 cm, respectively. Length-weight relationship (LWR) of tub gurnard were determined as W=0.0123L2.9757 for all individuals in the study. The value of the parameter ‘b’ was found negative allometric growth for tub gurnard. The food components of male and female tub gurnard were determined to 75.540±0.303, 75.801±0.69 for moisture 20.130±0.024, 19.151±0.023 for protein, 2.764±0.042, 3.704±0.059 for lipid, 1.550±0.042, 1.530±0.059 for ash, 0.434±0.121, 0.281±0.041 for carbohydrate and 141.677±0.062, 144.432±0.057 energy (kcal), respectively. In the study, it was determined that the biological fetures and nutrition composition values of tub gurnard vary as gender.
