Abstract

Species composition and seasonal variations of fish in the Five West Sea Islands in Korea, were investigated by using otter trawls and bongo nets from 2014 to 2015. During the surveyed period using an otter trawl, a total of 53 species, 147,253 ind./㎢ and 2,721,296 g/㎢ of fish were collected by otter trawls. The individual dominant species were Chaeturichthys stigmatias (30.3%), Coilia nasus (18.2%), Engraulis japonicus (12.3%), and Setipinna tenuifilis (12.2%). Moreover, the biomass dominant species in biomass were Liparis tanakae (21.3%), Beringraja pulchra (18.5%), Engraulis japonicus (8.3%) and Okamejei kenojei (8.1%). Eggs by bongo nets included 1,748 ind./1,000 ㎥ of Engraulis japonicus and 64,691 ind./1,000 ㎥ of unidentified species. A total of 15 species and 2,015 ind./1,000 ㎥ of fish larvae were collected, and the dominant species were Johnius belengerii and Pholis fangi.
