This study was conducted to understand the relationships between fish and zooplankton of distribution in the coastal waters of the East Sea from May to August 2016 using hydroacoustic. To distinguish between fish and zooplankton, we used the time varied threshold (TVT) method at the frequency of 120 kHz. As a result, the mean nautical area scattering coefficient (NASC) of fish was highest at 913 m2/n.mile2 in June and lowest at 315 m2/n.mile2 in July. The mean NASC of zooplankton was highest at 247 m2/n.mile2 in May and lowest at 70 m2/n.mile2 in July. The mean NASC of fish and zooplankton showed a significant difference (P < 0.05) with high correlation (R2 = 0.84). In addition, there was no significant difference in the mean NASC of fishes and zooplankton by depth (t-test, person correction = -0.17, p > 0.05).
