Özet

In this study, it was investigated that changed catch composition reflected on characteristics of small scale fishing gear in Gokova Bay. For this purpose technical characteristic of fishing gears, used in cooperative members of Akyaka, Akcapinar and Akbuk, were identified. FAO standardizations were taken into consideration when technical drawing of fishing gear. The changes in fishing gears have been presented to be compared with the previous studies in the same region. In total 11 different nets, 5 gillnet, 5 trammel net and combine (gill-Ftrammel net), were identifies in the Gokova bay. In additon, 3 different longline called thin, middle and thick were presented. The most important changes were found in gillnets. While three type of gillnets, red mullet, Atlantic bonito and sardine were used before 2005, five different gillnets, red mullet, pink dentex, yem baligi, air species, Atlantic bonito were identified. For trammel nets, shrimp and bilidye nettings are no longer used. There are some differences on technical structures (hanging ratio, length, height, etc.) of both gill and trammel nets used before and after 2005. Possible reason for these differences in inhabiting of lessepsian and invasive species and to begin to exploit them commercially. In such areas where catch composition changes, similar studies will be repeated at certain times to contribute to better management of fisheries.
