Abstract
The study was carried out via dock samplings with artisanal fishermen, who are fishing around sea-cages in Güllük Bay in the southeast of the Aegean Sea. The daily fishing activity of bogue (Boops boops) gillnetters was monitored randomly based at the ports of Göltürkbükü, Gündoğan, Yalıkavak and Torba during two fishing seasons from November to April in 2018 and 2019. 18163 kg of fish were captured from the bogue gillnet fishery during 147 daily operations. A total of 47 species belonging to 30 families of fishes (including invertebrates) constituted the ‘catch composition’ from the bogue gillnet fishery. As a target fish, Boops boops was naturally most abundant (91.9%) followed by Diplodus annularis, Scomber colias, Trachurus trachurus, Pagellus acarne, Scomber scombrus, respectively. Biomass ratios of the total by-catch to commercial bogue were found to be the ratio of 1: 0.09. The FL and weight distribution of 536 bogue samples ranged from 25.5 ± 0.12 cm and 293.6 ± 3.87 g respectively. B. boops seem to have the highest CPUE in April with 58.83 ± 11.47 kg.1000 m-1, therefore it is much more captured during its spawning migration to the open sea area in the Spring season.
