Seasonal (summer-winter) difference of the trammel net catch composition in Urla (Izmir, Turkey)

In this study, it was aimed to determine the effects of trammel net fishery in summer and winter periods in Urla (Izmir, Turkey). Samplings were carried in six fishing grounds located around the Karantina island in Urla region. Fishing was carried out in the same fishing area with trammel nets having the same technical characteristics. The catch per unit effort values of the trammel nets were calculated for each period. Statistical difference was observed between summer and winter on average length and distribution of the seabream (Sparus aurata) which is one of the most important and targeted species for this fishing method. Although the catch efficiency was high in the summer period, larger fish were caught during the winter period in comparison to summer. © 2020 Universitatea din Oradea. All rights reserved.
