A New Maximum Length with Length–Weight Relationship of Tub Gurnard (Chelidonichthys lucerna Linnaeus, 1758) from Central Black Sea Coasts of Turkey

Abstract

The study was carried out in the 2012-2016 fishing seasons in the Central Black Sea coasts of Turkey. Tub gurnard (Chelidonichthys lucerna L., 1758) were examined in the commercial fishery (trawls, trammel nets and gillnets). A total of 56.104 kg tub gurnard was caught during the study period. Total length and weight of 117 tub gurnard individuals were measured. Minimum, maximum and average total lengths were calculated as 12.8 cm, 74.2 cm and 33.28±1.28 cm, respectively. The maximum length is the second maximum length for the Black Sea coasts however first maximum length for the Central Black Sea coasts of Turkey. Length-weight relationship (LWR) of tub gurnard were determined as W=0.0103L2.9876 in the study. The value of the parameter ‘b’ was found to be 2.9876 and the growth was isometric (b = 3) for tub gurnard (P > 0.05).
