Distribution of Demersal Fish Based on a Combined Acoustic and Trawl Survey during Day and Night in Costal of the South Sea, Korea

An acoustic and trawl pilot survey using a small vessel was conducted in Jinhae bay of the South Sea of South Korea on April 13~14, May 11~13 and June 8~10, 2015. During the survey, acoustic data was collected and bottom trawls were conducted at the same time. First, various noises were eliminated by using the Park method based on the Wang method (Wang et al., 2015;Park et al., 2015), the species compositions and catch rate from each bottom trawl were observed, and spatial distribution of fishery resources in the water column and their nautical area scattering coefficient (NASC) were investigated through acoustic data. During the entire survey period, 12 orders, 33 families and 41 species were caught.The most caught species in April, May and June were Okamejei kenojei, Zoarces gilli and Pholis nebulosa, respectively.
