초록

2015년부터 2017년까지 우리나라 넙치 양식장에서 발생하는 폐사피해를 표본조사를 통해 모니터링 하였다. 표본어가는 전국의 수산질병관리원과 지속적으로 거래하고 있으며 현장방문을 통해 설문이 가능한 양식어가 중 층화구조분석을 통해 선정 하였다. 수산질병관리사 조사요원의 직접적인 현장방문을 통한 설문 조사를 수행하여 객관적으로 양식현황 및 폐사 현황을 파악하였다. 조사기간 중 24.78%/2015년, 30.19%/2016년 그리고 21.59%/2017년의 누적 폐사율을 나타내었고, 감염성 질병에 의한 폐사는 스쿠티카증(2015-2017년 평균 누적 폐사율: 56.7%)과 바이러스성출혈성 패혈증 감염(추정)(2015-2017년 평균 누적 폐사율: 8.9%)에 의한 피해가 높은 것으로 나타났으며, 제주에서는 여윔증(2016-2017년 평균 누적 폐사율: 10.3%)에 의한 피해가 높게 나타났다.

A monitoring was performed to survey the mortalities that had occurred in the aquaculture farms of olive flounder (Paralichthys olivaceus) in South Korea from 2015 to 2017. The indirect inquiry for entire farms and the sample survey for selected farms were carried out. The aquatic organism disease inspectors, who have a national license for the diagnosis and prevention of aquatic organism diseases and a have close relationship with the farms, investigated the rates and causes of mortalities according to the standard manual. The mortality rate by sample survey of farms in 2015, 2016, and 2017 were 24.78% (Chunnam: 17.86%, Jeju: 28.69), 30.19% (Chunnam: 24.45%, Jeju: 32.65), and 21.59% (Chunnam: 10.57%, Jeju: 26.00%), respectively. The major cause of mortality was scuticociliatosis, and the mortality caused by viral hemorrhagic septicemia and emaciation disease (Jeju) were also high. Our results can contribute to effective establishment prevention of epidemics system and acquired status as a disease-cleansing country.
