PENDUGAAN DAERAH PENANGKAPAN IKAN LAYANG DENGAN CITRA SATELIT DI PERAIRAN ACEH SEKITAR PIDIE JAYA

Abstract

The fishing ground of fish Scads always in a state of change and move in a way following the changes in environmental conditions that naturally fish would choose a more suitable habitat. Fishermen in Pidie Jaya determine fishing grounds only by looking at natural signs, learned from generation to generation, so this method is less effective in fishing ground. The use of satellite remote sensing have been shown to play a key role in the study of Oceanography fisheries for predicting the fishing area. This research aimed to determine the amount of the catch and to measure fish length, to specify the spread of chlorophyll-a and SST. The fishing ground map was created to prediction potential distribution around Pidie Jaya. The method used in this study is survey was following directly into the fishing area and interviewing the mini purse seine ship captain. The concentration of chlorophyll-a in the location of fisheries during the study ranged from 0,13-0,85 mg/m³ and an average 0,35 mg/m³, while the temperature of the sea surface with an average value of 29,25°C. Scads fish length caught during the months of September through November ranged from 17,9-21,9 cm long with an average that is 19,7 cm. The potensial of Scad fishing ground off the coast of a fish landing base (PPI) to the fisheries is > 6 nautical miles offshore.
