Abstract

Age estimation and sexual dimorphism of Coreoleuciscus splendidus were estimated using otolith, length-frequency distribution and 23 morphological measurements, from 245 individuals collected from September 2016, February and April 2017 in the Gapyeong stream, Han River, Korea. Result of age estimation of C. splendidus, we most examined were 2, 3 and 4-age, and the maximum observed ages were 5-age. Nine out of twenty-three morphometric measurements were significantly different between the genders. Anal fin have showing major sexual dimorphism in particular between adult individuals. This sexual dimorphism was based on extension of anal fin soft rays of male individuals. Therefore anal fin of males is always longer and wider than females. During spawning season male individuals possess nuptial tubercles on anal fin rays. However, another measurements and morphological characters does not exhibit sexual dimorphism in the between male and female individuals. The sexual dimorphism was observed to only over 2-years old individuals with sexual maturity. But juvenile and 1-years old individuals do not have sexual dimorphism with sexual maturity. Peak season of spawning was April to May and they start first spawning at 2-age. The ages at major spawning groups were most 3-age, and they maximum GSI index was 14.91 (female), 8.96 (male) at 5-age, respectively.

경기도 가평군의 가평천 일대에서 2016년 9월과 2017년 2, 4월에 쉬리 245개체를 채집하여 이석과 전장빈도분포법을 이용한 연령추정과 23가지의 계측형질을 이용하여 연령에 따른 성적이형을 조사하였다. 연령추정 결과 만 2년생부터 만 4년생의 비율이 높았고 만 5년생이 최대연령이었다. 23개의 계측형질 중 9개의 형질에서 성별 간에 유의한 차이가 있었다. 이중 뒷지느러미에서 나타나는 성적이형은 수컷의 뒷지느러미 연조가 길게 신장되어 뒷지느러미 폭과 길이가 암컷에 비해 넓고 긴 특징을 보이는 주요한 성적이형으로 나타났다. 또한 산란기에 수컷개체는 뒷지느러미의 연조에 추성이 발달하는 성적이형을 나타내었으나 뒷지느러미를 제외한 다른 계측형질과 외부형질에서 성별에 따른 성적이형이 나타나지 않았다. 성적으로 성숙하는 만 2년생 개체부터 성적이형이 나타났으며, 당년생 치어와 만 1년생 개체에서는 성적이형이 나타나지 않았다. 산란기는 4월에서 5월이었으며, 만 2세부터 산란에 참여하였다. 주요 산란 연령은 만 3세부터였으며, 최대 생식소 도지수(GSI)는 만 5세에서 암컷 14.91, 수컷 8.96으로 나타났다.
