Studies on the saprolegniasis in coho salmon oncorhynchus kisutch walbaum vi. pathogenicity of saprolegnia isolated from cultured coho salmon oncorhynchus kisutch walbaum on salmonids



Bulletin of the Nippon Veterinary and Zootechnical College (38): 44-51



Difference in the pathogenicity of fish to Saprolegnia parasitics COKER, which has been isolated from a Saprolegnia-infected coho salmon, was examined using 6 salmonids obtained from Miyagi Prefectural Freshwater Fisheries Experimental Station and 3 lines of rainbow trout obtained from Nikko branch of National Reserach Institue of Aquaculture. The susceptibility of 6 fishes of the experimental station was found to be in the following order: masu salmon (Oncorhynchus masou) and yamame salmon (landlocked salmon, Oncorhynchus masou) > Japanese char (Salvelinus Pluvius) > rainbow trout (Salmo gairdnerii) and coho salmon (Oncorhynchus kisutch). The susceptibility order of 3 rainbow trout lines of the research institute was rainbow trout > Steal head > Donaldoson stock. Such a tendency of their susceptibility to Saprolegnia corresponded to the naturally occured saprolegniasis which is generally observed during spawning seasons. In yamame salmon, no difference was found between Hokkaido origin and Fukushima origin when an abrasion treatment with fish net was performed for 2 minute prior to the immersion of zoospores suspension (Ab group). When the treatment was not performed (Nab group), however, Hokkaido origin which has a high smoltification rate showed higher susceptibility than Fukushima origin whose smoltification rate is low. A possibility was suggested as an explanation for this result that a difference in the skin structures between smolt and parr would affect the susceptibility.
