Abstract

Scuticociliatosis can occur from juveniles to adult olive flounder (Paralichthys olivaceus) and the infection usually causes mass mortality. There is no clear way to treat it once the parasite has invaded the fish's internal organs. Therefore, periodic monitoring of scuticociliatosis for surveillance and prompt response is a crucial part of reducing damage to olive flounder farms. In this study, we conducted scuticociliatosis monitoring of olive flounder farms in jeju island to investigate the detection rate of the causative agents (Miamiensis avidus and Uronema marinum), and determine the phylogenetic classification of the detected pathogens. Disease monitoring was conducted on a total of 3,282 olive flounder and the detection rate was highest in August (15.83%) during the investigation period. The sequences of all 4 strains obtained from olive flounder farms in 4 different regions, were 100% homologous with SSU rRNA gene of M. avidus deposited in GenBank.
