Özet
The red cornetfish (Fistularia petimba Lacepède, 1803) is an invasive fish species commonly found along the eastern Mediterranean coast of Türkiye. This study examined the length-weight relationship (LWR), condition factor (Fulton-K), and hepatosomatic index (HSI) of F. petimba specimens by sex. Between 2021 and 2024, 306 individuals (♀: 224, ♂: 56, juvenile: 26) were collected as bycatch from commercial fishing vessels in Taşucu Bay, Mersin Province. The sex ratio was 1:0.3 (♀:♂). The length-weight relationship was W = 0.0002×L3.289 (r2 = 0.952) for all individuals, W = 0.0002×L3.222 (r2 = 0.949) for females, and W = 7E-05×L3.514 (r2 = 0.951) for males. Positive allometric growth was detected. Fulton-K condition factor values were 0.49±0.03 for all individuals, 0.50±0.03 for females, and 0.47±0.06 for males. Hepatosomatic index (HSI) values were 0.85±0.05 for all individuals, 0.94±0.06 for females, and 0.57±0.08 for males. The data from this study on the red cornetfish population in Taşucu Bay, Mersin Province, may contribute significantly to understanding the body dynamics of the species.
