Abstract

Specimens were collected from the coastal region near industrial complex of Ulsan-Onsan, Sihwa-Ansan and Yeosu-Gwangyang in 2008 and 2009. The total number of individuals used in analysis was 1,289 of Acanthogobius flavimanus, Chelon haematocheilus, Hemibarbus labeo, Leiognathus nuchalis, Mugil cephalus and Synechogobius hasta. The sex ratio in the total individual was 1:0.73 (female:male). Specific sex ratio of fishes in the areas, namely the Ulsan-Onsan, Sihwa-Ansan and Yeosu-Gwangyang were 1:0.79, 1:0.81, and 1:0.25, respectively. Especially, female in Yeosu-Gwangyang was higher than male. The intersexuality in the total individual was 11.7%. Intersexuality of fishes in the areas were 4.98, 14.39 and 25.0% in the Ulsan-Onsan, Sihwa-Ansan and Yeosu-Gwangyang, respectively. It was indicated female higher than male in Ulsan-Onsan and male higher than female in Sihwa-Ansan and Yeosu-Gwangyang.

분석에 이용된 어류는 울산/온산, 시화/안산 및 여수/광양의 산업단지 인근 해역에서 2008년과 2009년에 채집하였다. 분석에는 문절망둑 (Acanthogobius flavimanus), 가숭어 (Chelon haematocheilus), 누치(Hemibarbus labeo), 주둥치 (Leiognathus nuchalis), 숭어 (Mugil cephalus), 풀망둑 (Synechogobius hasta)1,289개체가 사용되었다. 전체 개체의 성비 (암:수)는 1:0.73이었다. 각 지역별 성비는 울산/온산에서는 1:0.79, 시화/안산지역에서는 1:0.81, 여수/광양지역에서는 1:0.25로 암컷의 비율이 높았다. 전체 intersex 출현율은 11.7%였다. 각 지역별 intersex 출현율은 울산/온산에서는 4.98%, 시화/안산지역에서는 14.39%, 여수/광양지역에서는 25.0%로 나타났다. 성에 따른 intersex 출현율은 울산/온산에서는 암컷에서 높았으나 시화/안산과 여수/광양에서는 수컷에서 높았다.
