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).
Highlights
The Black Sea, an almost closed basin between Europe and the Anatolian peninsula, is one of the youngest seas in the world and connected to the Aegean Sea via the narrow Bosphorus and Dardanelles
The aim of the present study is to supply new data on maximum length, length weight relationship (LWR) and fishery of tub gurnard caught in the Central Black Sea coastal fisheries of Turkey
Total length and weight of 117 tub gurnard individuals were measured in the study
Summary
The Black Sea, an almost closed basin between Europe and the Anatolian peninsula, is one of the youngest seas in the world and connected to the Aegean Sea via the narrow Bosphorus and Dardanelles. Eukaryotic life occurs in only 10% of the total depth of the Black Sea (Balkas et al, 1990; Bat et al, 2007; Talley et al, 2011; Bat, 2017). Tub gurnard (Chelidonichthys lucerna) is one of the three species belong Triglidae family living in the Black Sea (Bat et al, 2008; Bilecenoğlu et al, 2014; Yankova et al, 2014). It is a nectobenthic fish distributed in the eastern Atlantic from Norway to Senegal, Mediterranean and Black Sea (Serena et al, 1998) and mainly habits sand or gravel bottoms up to 320 m depth (Mytilineou et al, 2005).
