Chlorophyll-a Concentration Derived Satellite Impact on Sardinella Lemuru in Bali Strait During Indian Ocean Dipole 1997 and 2006

Abstract

The Bali strait region has loong been considered as an importent area for oily sardine fisheries.The productive plagic fisheries in this area are sustained through enhanced biological produktion during seasonal upwelling the study is aimed at during variavility of chlorophyll-a (chl-a) conceration during indian ocean dipole (IOD) 1997 and 2006 and assessing their impact on sardinella lemuru production.Monthly mean chl-a concentration during 1997-2007 in Bali Strait drived sea WiFS satellite imagery
