摘要

This study was conducted to determine the effect of using trammel used by small-scale fishermen for catching red mullet species (Mullus barbatus, Mullus surmuletus, Linnaeus 1758) on catch efficiency and bycatch. Within the scope of the study, a total of 28 trials were conducted along the coasts of Çanakkale Province between June 2023 and March 2024.

In the trials, a total of 31 species belonging to 17 families were captured. A total of 1706 fish weighing 99.906 kg were caught with trammel nets having a 20 mm inner panel mesh size, and 1534 fish weighing 92.468 kg were caught with gillnets of 20 mm mesh size. The number of red mullet species, was 107 in trammel nets and 230 in gillnets. The gillnets caught 2.15 times more of the target species than trammel nets. 25 species were caught with trammel nets and 19 species with gillnets. While threatened species like Squatina squatina and Scyliorhinus canicula were caught in trammel nets, none were caught in gillnets. In terms of by-catch species, trammel nets caught 1.27 times more than gillnets (P < 0.05). Therefore, gillnets used for red mullet fishing along the North Aegean coast have been found to be more efficient.
