【 摘 要 】

Pelagic fish are spesies that live in water column at depth of 100 to 200 meters from surface. They migrate as a grouplooking for nutrient and spawning place. Potential fisheries comodities in Indonesia including pelagic fish have higheconomic value. Then, stock assessment of pelagic fish measurement is important to researched. The research wasconducted in May – June 2016 surrounding South China Sea waters using Madidihang 02 Research Vessel operated byMarine Fisheries Affair (MFA) Republic of Indonesia. To estimate the density of pelagic fish hydro-accoustic equipmentand oceanography parameters were used and measured during the campaign. The split beam echosounder was use in aimto obtain precission position and number of fish target. The highest density of fish was found around Tambelan Islandand Anambas Island. Statistically pelagic fish density has correlation with chlorophyll-a, salinity, temperature, and seacurrent velocity. The statistical analysis between pelagic fish density and those oceanography parameters (as statisticvariables) yields positive vector correlation.
