Kajian Daerah Penangkapan Ikan Pelagis Besar Berdasarkan Data Produktivitas Primer Bersih Di Samudera Hindia

Net ocean primery productivity is one of the indicators that are categorized as important, if the water has a high fertility, it can be indicated as an area of good fishing ground. This study aims to determine the temporal and spatial characteristics of big pelagic fish, the relationship parameter of net primary productivity (NPP) with the catch per fishing effort (CPUE). This study uses QGIS 2.18 and microsoft excel. Fisheries data used is the data logbook big pelagic fish with longline fishing gear in the Indian Ocean in 2013 and the remote sensing data obtained from Aqua MODIS image sateli Level 4. Data analysis consisted of: the analysis of image data, density analysis CPUE and analysis of the relationship between two variables using regression linear simple. Value maximum NPP smonthly periods, namely 7.492 gCm2/day in February while on a seasonal maximum value is 6,916 gCm2/day on the second transitional season. The maximum value CPUE of monthlythere in August that 1,250 birds/1000 hook while a seasonal maximum value that is contained in West season 583,33/1000 hook. Judging from the relationship and influence NPP with CPUE the highest monthly period in September had a fairly close relationship that is 0.5 where the influence of the NPP on CPUE by 24,31% while the period of seasonal in seasonal transition II had a fairly close relationship that is 0,5 where the influence of the NPP on the CPUE of 24,31%. Need to do further research, see other parameter tha influence CPUE big pelagic fish. Keyword: Big pelagic fish, Indian Ocean, koifisien correlation (r), net primary productivity (NPP).
