Abstract: The present disclosure relates to genetic markers for discrimination and detection of bacteria causing Edwardsiellosis and Streptococcosis in fish, and a method for discriminating and detecting the bacteria using the same. A genetic marker for discrimination and/or detection of each of Edwardsiella tarda, Streptococcus iniae, Streptococcus parauberis and Lactococcus garvieae, which cause fish diseases, is selected and a peptide nucleic acid and a primer pair, which are specific for the genetic marker, are used to amplify and obtain melting curves having different fluorescences depending on bacterial species. Thus, bacteria that cause fish diseases can be discriminated and whether or not fish would be infected with the bacteria can be detected in a simple, rapid and accurate manner.

Abstract: The present invention relates to a composition containing Ivermectin for exterminating Clavinema mariae infection on Sebastes schlegeli, and more specifically, to a composition for exterminating Clavinema mariae infection on Sebastes schlegeli, containing Ivermectin as an active ingredient, and a method for exterminating Clavinema mariae infection by orally administering Ivermectin to Sebastes schlegeli. The composition and the exterminating method according to the present invention are excellent in an effect of exterminating Clavinema mariae infection of Sebastes schlegeli, are safe without causing any side effects on the Sebastes schlegeli, and are able to achieve oral administration to thereby be useful in the aquaculture industry.
