Pendugaan Daerah Penangkapan Ikan Tuna Sirip Kuning (Thunnus Albacares) Di Perairan Sumatera Barat Melalui Pendekatan Maximum Entropy
Abstract
Fishing areas are beneficial for fishing fleets to determine the target fish
locations. The Maxent method estimates the distribution of maximum entropy
opportunities by calculating the data that is the most spread out, close together,
or uniform. This research uses MODIS sensor recording data in images of sea
surface temperature and chlorophyll-a concentration level-3, Standard Mapped
Image (SMI), and fishing logbook data. The results showed that catching
yellowfin tuna should be done in the transitional season I and transition season
II, which showed the AUC value on the ROC curve was in the range of > 0.9.
The jackknife test concluded that chlorophyll-a influenced the spatial catching
of yellowfin tuna (Thunnus albacares). The response curve results for the
probability index value of the presence of yellowfin tuna with the highest sea
surface temperature in the range of 32.1 °C and the chlorophyll-a parameter in 1
mg/m3. The presence of yellowfin tuna is at the HSI value ranging from 0.16 to
0.91; the model's accuracy is good to very good.
Keywords: yellowfin tuna; chlorophyll-a; maximum entropy; west Sumatera
waters; sea surface temperature
