Monitoring of diseases in wild marine fish stocks collected in June 2006 by a trawl in the Southern Korean Waters

2006년 6월에 트롤어법으로 어획된 남해안 자연산어류에 대한 질병 모니터링

Abstract

Viral and bacterial pathogens of the wild marine fishes were monitored in 176 wild fish and 15 wild shrimp from 13 and 1 species, respectively, which were captured by a trawl net in the southern sea of Korea during June 2006. Viral pathogens that are common etiologically agents to cultured fish in Korea were not isolated. One and 5 bacterial strains were affiliated to the genus Proteus and Pseudomonas, respectively, but these bacteria do not seem to be associated with mortality of aquacultural fish. An extended monitoring on wild marine fishes were necessary for identification of agents responsible for the cultured fish infections.

자연산어류의 질병 감염 실태를 파악하기 위하여 2006년 6월에 남해안 해역에서 트롤에 의하여 어획된 개체 중 13 종 176 개체의 어류와 1 종 15개체의 새우류 등 총 191 개체의 자연산어류에 대한 바이러스성 및 세균성 질병에 대한 모니터링을 실시하였다. 조사 결과 우리나라 양식 어류의 주요 질병과 관련한 바이러스성 병원체의 존재는 확인되지 않았다. 시료 6 개체에서 세균이 분리되어 확인한 결과 Pseudomonas속 세균 5 균주와 Proteus속 세균 1균주가 확인되었으나 양식 어류의 폐사와 관련한 세균군은 아닌 것으로 판단되며, 양식산어류의 질병 발생에 대한 관련성을 밝히기 위하여 자연산어류에 대한 더 많은 조사가 필요할 것으로 사료된다.
