| 内容記述 | The skin fluke Benedenia seriolae is a parasite specific to Seriola species. It feeds on the epidermal tissues of yellowtail (Seriola quinqueradiata) and causes external injuries that render the fish susceptible to bacterial and viral infection. Infection with this parasite is a serious problem for yellowtail aquaculture because it also leads to a reduction in fish growth. A previous study has reported the existence of an inherited Benedenia disease-resistance factor in yellowtail. Any yellowtail families resistant to Benedenia disease have not yet been produced, although the production of such families for aquaculture would potentially help to reduce not only infectious diseases but also the labor costs to eradicate Benedenia. In this study, we investigated time series changes of the number of Benedenia parasites on each host yellowtail for the purpose of selecting Benedenia resistant broodstock candidates. In September 2014, the number of individual parasites on 100 fish that were selected randomly from 10,000 wild-caught 0-age yellowtail at an aquaculture farm was investigated and it ranged from 1 to 48 individuals / fish. Thus we selected 961 fish that has the lowest 10% parasite susceptibility (3 or fewer Benedenia). The selected fish were then cultured in sea net cages and the number of parasites on each was counted at five times between November 2014 and July 2015. The average number of parasites per fish had a wide range from 0.2 to 39.4 individuals / fish over this period, and the overall mean was 8.9 individuals / fish. One hundred sixty fish with lower than 3 parasites were selected as broodstock candidates. We are now using these broodstock candidates as parents to produce F1 yellowtail families for Benedenia-resistant analysis using DNA marker-assisted-selection breeding methods. | |||||||
