Abstract

In order to investigate the effect of chlorine disinfectant against white spot baculovirus (WSBV), 5, 10, or 30 ppm of sodium hypochlorite (NaOCl) was treated to the WSBV-infected shrimp, Penaeus chinensis. In contrast with the non-treated control, no shrimp was dead after of sodium hypochlorite treatment. This result indicated that WSBV was inactivated by chlorine treatment. No inactivation of WSBV was observed by 10, 20, 30 ppm of povidon-iodine treatment. WSBV was also inactivated by 2, 4 hr sunlight exposure and by 1, 2, 3 hr drying. WSBV was inactivated very effectively by addition of fresh water on sea water.

WSBV를 염소소독 효과를 조사하기 위하여 유효농도 5, 10, 30 ppm의 차아염소산나트륨 용액을 처리한 결과 전혀 폐사가 일어나지 않았으나, 대조구에서는 전량 폐사되었다. 포비돈 요오드 10, 20, 30 ppm에서는 불활성화를 나타내지 않았는데 이는 유기물의 다량함유나 요오드 독성에 의해 시험새우가 폐사할 가능성이 있다. 일광소독에서는 2, 4시간 처리한 시험구에서는 폐사가 일어나지 않으므로 WSBV를 불활성화 시키는 것 같다. 건조처리에서는 1, 2, 3시간 처리한 시험구에서는 WSBV가 불활성화가 되었다. 담수처리에서는 담수 60% 첨가한 시험구(비중 1.015)에서 효과가 가장 크게 나타났다.
