Abstract

Aquatic animal raised in hatcheries play an important role in supplying seedling to stock enhancement and seed quality, especially, seed health is the key factor for survival in the field after release and for stocking effectiveness. We have inspected the hatchery-reared seeds of 33 marine species and 12 freshwater species for legally designated diseases in stock enhancement program in 2010. Results showed that abalone was the most abundant as 20.0% in the marine species group and then sea cucumber (15.6%), olive flounder (8.4%), rockfish (6.7%), black sea bream (6.3%) and swimming crab (6.1%) were followed. Crucian carp was the most abundant as 19.4%, and then eel (11.8%), Korean bullhead (10.9%), mandarin fish (10.8%), melanian snail (8.4%), catfish (7.7%) were followed in the freshwater species group. The total number of inspection cases for eight pathogens in this study were 2,105 and disqualification cases were 30 by detection of aquatic animals pathogens such as koi herpesvirus (KHV), red sea bream iridovirus (RSIV), white spot syndrome virus (WSSV) or viral haemorrhagic septicemia virus (VHSV).

배양장에서 생산된 양식생물은 자원조성에 필요한 종묘를 제공한다는 측면에서 매우 중요한 역할을 담당하고 있으며, 방류종묘의 질, 특히 개체의 건강도 는 방류이후 서식처에서 생존하고 자원조성 효과를 결정짓는데 매우 중요한 요소가 된다. 2010년도 방류 품종(해면품종 33종과 내수면품종 12품종)을 대상으로 수산동물전염병의 감염 여부를 검사하였다. 검사 품종 중에서 해면품종으로는 전복이 20.0%로 가장 많았으며, 그 다음 해삼(15.6%), 넙치(8.4%), 조피볼락(6.7%), 감성돔(6.3%), 꽃게(6.1%) 순으로 나타났다. 내수면품종 중에서는 붕어가 19.4%로 가장 많았으며, 그 다음으로 뱀장어(11.8%), 동자개(10.9%), 쏘가리(10.8%), 다슬기(8.4%), 메기(7.7%)의 순으로 나타났다. 총 45개 품종을 대상으로 1,120회의 검사가 의뢰되었으며, 검사 항목별로 2,105건의 검사를 실시한 결과 30건에서 koi herpesvirus (KHV), red sea bream iridovirus (RSIV), white spot syndrome virus (WSSV) 또는 viral haemorrhagic septicemia virus (VHSV)와 같은 병원체가 검출되어 불합격 처리되었다.
