Abstract

The main purpose of this study is to contribute to Turkish
tuna fishing fleet management. In this context; The Turkish Bluefin Tuna (Thunnus
thynnus Linnaeus, 1785) fishing fleet in our territorial waters and
international waters in the Eastern Mediterranean were monitored on a
spatio-temporal basis and a continuous monitoring model for BFT stock was
established. Archival data sets of Bluefin Tuna (BFT) 2010-2016
spatial-temporal migration and remote sensing data sets of traces of fishing
vessels and environmental factors (SST and Chl-a) were included in the
model. Statistical analysis of the model was performed using Geographical
Information System (GIS) based-approach and the results were presented on
thematic maps. On the other hand, the
importance of the announcement of The Exclusive Economic Zone (EEZ) for BFT
fishing in Eastern Mediterranean was addressed in the study. Accordingly, the
possibility of 'Turkey's Exclusive Economic Zone' announcement in Mediterranean
Sea and its borders were discussed.
