Abstract

The aim of this study is to provide an overview of the Gaidropsarus mediterraneus (Linnaeus, 1758) species growth pattern from the Romanian Black Sea Coast, in the year 2023. This has been accomplished by studying the length-weight relationship, an important parameter, which helps to know the growth pattern of fish populations, Fulton’s condition factor (kc) (useful index for monitoring feeding intensity) from 180 shore rockling individuals caught by pots. Average lengths and weights were 24.4 ± 2.6 cm and 101.46 ± 38.11 g, respectively, the minimum and maximum values were 18.3 and 33.8 cm, 36 and 319 g in weight. The value of exponent b in the equation is 3.197, indicating that the increasing weight is allometrically positive and mean value of the Fulton was 0.68 ± 0.08, with the minimum and maximum values of 0.47 to 0.90. The obtained results can have useful effects on the stock management of this fish species.
