    12. 12 Parasitic Disease

    13. 13 Scuticociliatosis 18.This is a olive flounder infested by Scuticociliatida parasite. There were known two species of ciliates, Uronema and Miamiensis. The parasite can invade variously, skin, muscle, peritoneal cavity, kidney and characteristically brain. Also, they can make ulcer on the body surface. Most of attacked fish showed high mortality. 18.This is a olive flounder infested by Scuticociliatida parasite. There were known two species of ciliates, Uronema and Miamiensis.

    22. 22 Cumulative mortality and RPS of olive flounder had vaccinated by im injection with FKC S. iniae by challenged with 1×108 cells of S. iniae per fish at 3 weeks

    32. 32 Summary Disease control and Prevention in Mariculture 1) Laboratory - Develop a new chemotherapeutic drug - Vaccination on major infectious endemic disease - Immunostimulant development with medicinal herbs etc 2) Farmer - Use to disinfectant in land based culturing farm for prevention from pathogen spreading - Substituted moist pellet to the commercial extruded pellet
