Outline of Final Research Achievements

Three species of blood flukes of the genus Cardicola were identified from farmed Pacific bluefin tuna (PBT). Their intermediate hosts, in which the three blood flukes use different terebellid polychaetes, were determined and their developmental stages were described. All the life cycles of the blood flukes infecting PBT were determined, which are completed within PBT farms. Nicolea gracilibranchis, the intermediatae host of Cardicola orientalis, was most abundant in water depth of 0-4 m, and showed highest prevalence of infection in July. It is estimated that an infected N. gracilibranchis can release up to 1 million cercariae. As for Kudoa infection, K. neothunni and a new species, K. hexapunctata were found in the skeletal muscle. Infection started soon after PBT seeds were transferred from indoor tanks to sea cages. In experiments using Seriola lalandi seeds and Kudoa yasunagai, infection occurred in fish using filtered water, but was prevented using UV radiated water at 15mJ/cm2.
