초록
The species and size compositions of fishes in the coastal waters off Taean were determined using samples collected with a two-sided fyke net in 2008. A total of 22 species, 2,371 individuals and 1,351 kg of fish were collected during the study. Of the fish collected, semi-benthic fishes such as Sebastes schlegelii, Mugil cephalus and Chelon haematocheilus were the most abundant (77.5% and 76.4% for total number of individuals and biomass, respectively). Benthic fishes such as Pleuronectus yokohamae and Paralichthys olivaceus were collected in almost all seasons but were low in abundance (5.3% and 4.1% for total number of individuals and biomass, respectively). Seasonal migrants were plentiful; specifically, Seriola quinqueradiata was abundant in November while Konosirus punctaus was common in July. Seasonal migrants of small-sized fish have been known to be abundant in the coastal water of western Korea including the study area, but few fish less than 100 mm were collected due to the large mesh size (30 mm) of the net used.
