Potential Fishing Ground For Tuna (Thunnus sp) Based On Mapping Of Sea Surface Temperature Distribution And Catches Data By Using Satellite Imagery Of Aquarius In Sumatra Waters

Abstract

The purpose of this study was to know the potential fishing ground of tuna
(Thunnus sp) by mapping distribution of sea surface temperature satellite imagery
of Aquarius and catched in waters of West Sumatra and then plotted estimated of
fishing ground in form of map. The analysis data was conducted in Fishing
Ground Laboratory Faculty of Fisheries and Marine Sciences University of Riau,
Pekanbaru. This study using Aquarius satelite imagery data level 3, with a 4 km
spatial resolution. In this study sea surface temperature ranging from 27,040C–
30,170C. Tuna was catched dominantly temperature in west season is in range
27,090C–29,280C, transition season I 27,040C–30,170C, east season 28,690C–
29,820C and transition season II 27,320C–29,540C. The catched with CPUE
highest value 7.5963 kg/day in August. The catches of all tuna is category viable
catch. The potential fishing ground were found ground of Siberut and Sipora
island waters.
