Abstract
In 2014, fishes caught using stow nets in coastal waters off Gochang from May to October were assessed for appearance patterns. The fishes were caught at four research stations (St.) and were found to comprise 37 species, 18 families, and 7 orders. The dominant species were Thryssa kammalensis, Setipinna tenuifilis, and Sardinella zunasi. To gain a measure of their biodiversity, all species were assessed for their number, richness, diversity, evenness, and dominance. The highest and lowest numbers of total fishes caught were recorded in September (4,819 individuals) and October (828 individuals), respectively. The diversity was the highest in October (H' = 2.478) and lowest in June (H' = 0.880). The evenness index was the highest in October (E = 0.780) and lowest in June (E = 0.343). The richness index was the highest in October (R = 3.424) and lowest in May (R = 1.552). Finally, the dominance index was the highest in June (D = 86.2%) and lowest in October (D = 40.3%).
