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%).

이 연구는 2003년 4월부터 7월까지 여수시 돌산읍 우두리 하동마을과 오천동 주변 하구역에서 검정망둑 어미를 채집하여 실험실에서 사육하면서 산란 습성, 난 발생 과정 및 자치어 형태 발달을 관찰하였다. 수정란은 전구 모양으로 난황은 무색이었으며, 알의 장경은 , 단경은 였다. 난막의 기부에는 많은 부착사가 있어서 부착하는 분리 부착란으로 여러 개의 작은 유구를 가지고 있었다. 부화는 수온 (평균 )에서 수정 후 154시간 40분에 시작하였다. 부화 직 The Tridentiger obscurus were collected of Ocheon-dong and Dolsan-do in Yeosu from Apirl to July 2003, and were carried to the laboratory to investigate their development of spawning habit, egg development, larvae and juveniles. The fertilized eggs were measured in diameter. Hatching of the embryo began about 154 hrs 40 mins after fertilization in water temperature of (mean ). The newly-hatched larvae were (mean 2.83mm) in total length (TL), their mouth and anus were opened, and the yolk sac was completely absorbed. At 21 days after hatching, the postlarvae were (mean 6.02mm) TL, and the tip of the caudal notochord was flexed upward. The juveniles stage was reached when all fin-rays were formed at 45 day after hatching, and (mean 13.45mm) TL.
