Abstract

This study was performed to determine the disinfection efficacy of influent seawater by application of mechanical filtration and UV disinfection system (MFUVDS) in decreasing disease outbreak of juvenile olive flounder (Paralichthys olivaceus). Bacterial disinfection rate of influent seawater following the MFUVDS application was 99.27%. Mortalities of the juvenile reared for 4 months were 20~30% lower than those of the control (25.8%~34.9%).

본 연구는 기계적 여과 후 자외선 살균처리한 양식장 유입수의 살균효율과 넙치 치어의 질병저감 효과를 평가하였다. 유입해수의 살균효율은 99.27%로 조사되었고, 기계적 여과 및 UV 살균처리 해수로 4개월 동안 사육한 넙치 치어는 대조구에 비하여 20~30%의 폐사율 저감효과가 관찰되었다.
