  • Lepeophtheirus tuberculatus, n. sp., is described from the greenlings Hexagrammos otakii and H. agrammus from the Sea of Japan off Mangreung, Korea. This species has been confused with L. scuttger Shiino, 1952 and L. sheni Boxshall and Bellwood, 1981. However, the new species apparently differs from the latter two species.

  • Thirteen species of sea lice (Copepoda, Caligidae) are described as parasites of marine fishes from Korea including three new species such as Pseudocaligus longipes n. sp. from Siganus fuscesens (Houttuyn), Lepeophtheirus tamladus n. sp. from Sebastes inermis Cuvier, and Lepeophtheirus gusevi n. sp. from Sebasetes schlegeli Hilgendorf. Remaining ten species are new to Korea: Caligus elongatus Nordmann, 1832; C. equulae Ho and Lin, 2003; C. fistulariae Yamaguti, 1936; C. laticaudus Shiino, 1960; C. rotundigenitalis Y$\ddot{u}$, 1933; Metacaligus uruguayensis (Thomsen, 1949); Lepeophtheirus atypicus Lin, Ho and Chen, 1996; L. parvulus Shiino, 1952; Anuretes quadrilaterus Shiino, 1954; and Pseudanuretes chaetodontis Yamaguti, 1936.

  • Infestations of parasites, particularly those caused by copepods and monogeneans, are a major hindrance to aquaculture and have a big negative economic impact. Sebastes schlegelii, a farmed Korean rockfish, is particularly prone to copepods and monogeneans. This study comprehended how parasitic copepods and rockfish from a farm in Tongyeong-si, Gyeongsangnam-do, Korea, are related to the monogenean trematode Microcotyle sebastis. Our research revealed that monogeneans predominated, with a rate of 98.4% and an average infection intensity of 7 per infected fish. With an average infection intensity of 4 per sick fish, the infection rate for parasitic copepods was equally considerable, coming in at 91.7%. The high co-infection rate of both parasite families, at 90.8%, is noteworthy. Furthermore, Lepeophtheirus elegans and Peniculus truncatus, 2 parasitic copepod species, were discovered to have M. sebastis eggs attached to their bodies. This demonstrates a connection between parasitic copepod infestations in farmed Korean rockfish and the monogenean trematode M. sebastis. These discoveries highlight the necessity for creating more potent parasite control methods for the aquaculture sector and shed light on the intricate relationships between various parasite species.
