Abstract

Sea surface temperature (SST) and a-chlorophyll (CHL) were important and they were often used to predict potential fishing ground by using remote sensing. The objectives of the present study were analysis and mapped fishing ground of skipjack in the Banda Sea and its surrounding Moluccas Province according to monsoon. SST and CHL data were taken from satellite citra data analysis, observed by sensor Aqua MODIS level 3 with spatial resolution 4 km and temporal resolution month and monsoon. Citra data were analyzed by using SEADAS 5.2. software. The analysis showed that sea surface temperature (SST) and a-chlorophyll concentration in the Banda Sea and its surrounding fluctuated from month by month. This condition affected seasonal fluctuation of SST and CHL. The average of highest temperature was in West monsoon and first transitional monsoon whereas the lowest was in East monsoon. Otherwise, a-chlorophyll concentration was highest in East monsoon and lowest was in first transitional monsoon. There was a correlation between temperature increasing and a-chlorophyll concentration decreasing. Sea surface temperature has also a negative correlation to CPUE and influenced fishing ground forming. Fishing ground in Banda Sea with highest CPUE during all monsoon was located on Western part of Seram Island: Buano, Kelang and Manipa Islands or situated on 126.70-1280 E and 2.60-3.40 S. The position surrounding Banda Sea lied on 127º-130.3º E and 3.2º-4º S.
