The Length–Weight Relationship and Condition Factor of a Non-Native Fish Species: Striped Sea Bream (Lithognathus mormyrus L., 1758) in the Black Sea

Abstract

In this study, length-weight relationship and condition factor of L. mormyrus were determined in the Black Sea. 306 individuals (170 female and 136 male) of the species were caught between 2017and 2018 with trammel nets. The mean length and the mean weight of the specimens were determined as 18.18 cm + 2.01 (Min:15.7 - Max:31.0) and 79.16 g + 38.20 (Min:49.23 - Max:393.8), respectively. The length - weight relationship was described by the following formula W = 0.0147 L2.9475 (R² = 0.9421) with a negative allometric growth. Fulton condition factor (K) was calculated, 1.17 for all samples.
