We investigated the ecological characteristics and proximate composition of Muraenesox cinereus off the southern coast of Korea. Anal length distribution, sex ratio, condition factor of M. cinereus individuals caught by costal complex (longline) fisheries were investigated from June to October 2018....

과거 국내 갯장어의 생산가격이 9월 부터 급격히 감소하는 이유는 무엇인가? | 그러나 생산가격은 가을이 시작되는 9월부터 급격히 감소하였다. 이러한 현상은 과거 국내 갯장어의 대부분 일본으로 수출되었으며, 8.15 광복절을 기점으로 수입이 중단된 탓에 가격이 급락했던 전례를 따른 것으로 판단된다. 그러나 최근 갯장어의 내수량이 높아져 수출량이 감소하고 있으므로(KTSPI, 2018), 현재 사정과 맞지 않는 가격변동 요인으로 판단된다. | |
우리나라 갯장어 어획량 현황은? | , 2007). 우리나라 갯장어 어획량은 1970-80년대까지 평균 6,000톤이었으나, 1990년대 2,257톤, 2000년대 1,090톤, 2010년대 1,239톤으로 감소 추세이다(KOSIS, 2018). 2000년대 이후 갯장어는 주로 남해안에서 어획되며, 전체어업의 약 70%가 연안복합어업에서 어획되고 있다(NIFS, 2017). | |
갯장어란 무엇인가? | 갯장어(Muraenesox cinereus)는 뱀장어목(Order Anguilli-formes) 갯장어과(Family Muraenesocidae)에 속하는 어종으로, 일본 중부이남, 황해, 동중국해, 인도·태평양 해역에 분포하며, 모래 진흙 바닥 또는 바위에 서식한다(Kim et al., 2005; Yamada et al. |
