Relationship of population density of oceanic sea skaters collected from tropical and subtropical zones in the Pacific Ocean was examined to chlorophyll concentration-Dissolved Oxygen concentration and biomass in surface sea water. The four parameters shown above were measured at the site of 12oN during the cruise, MR13-03 cruise, and at the site of 25oE during another cruise KH-14-02. Significant and positive correlation between all biomass especially invertebrates and population density of oceanic sea skaters collected with a Neuston-Net trailing during 15 min was shown in overall analysis on the data of the both samplings p < 0.001. Moreover, dissolved oxygen was much lower at 25oE than that at 12oN with similar value of chlorophyll value p < 0.001. These results would suggest that more food resource would be available at 25oE than that at 12oN for keeping high density population of oceanic sea skaters.
