Abstract: This study was conducted to examine the effects of regional wind changes on trawl fishing effort in Iskenderun Bay from 2017 to 2023 by analyzing meteorological data, daily fishing durations, and catch quantities. It was found that an increase in wind intensity reduced fishing durations by an average of 0.367 h. Northerly and easterly winds were observed to have higher speeds throughout the year, with the highest speeds reaching 14 m/s in March. Fishing activities were affected more by southerly and westerly winds due to the geographical structure of Iskenderun Bay. Seasonal variations were also detected, with fishing durations being longer at the beginning of the fishing season in autumn and decreasing in spring. Species such as red mullet, brushtooth lizardfish, and shrimp were identified as having a significant impact on fishing activities. The relationships between wind intensity, direction, and fishing durations were revealed through statistical analyses. It was shown that environmental and seasonal factors influenced trawl fishing effort in Iskenderun Bay. These results provided insights into the interactions between wind dynamics and fishing operations.
