  • Nineteen rockfishes representing two species in the family Scorpaenidae were collected from Oregon Coast Aquarium in July 2003 and examined for parasitic copepods. The parasitic copepods were taken from the gills of Sebastes crameri and fins of S. melanops. With regard to the prevalence of copepod 22.2% of the fishes were infected by C. uncinata, and 30.0% by N. robusta. Intensity of infections of Clavella uncinata to Sebastes melanops, showed a range of 4 to 6 with a mean of 5.0 per fish while Neobrachiella robusta to S. crameri was 1 to 6 with a mean of 2.7.

  • Parabrachiella trichiuri (Yamaguti, 1939), a copepod parasitic on the ribbonfish Trichiurus lepturus (Linnaeus, 1758), is recorded as a new record of Korean fauna. The copepod is the only known species of the family Lernaeopodidae parasitic on T. lepturus. Parabrachiella trichiuri can be differentiated from its congeners by a combination of characters: the trunk is pyriform, with two pairs of processes, the maxilla is less than half as long as the cephalothorax, and the genital process is not protruding from the margin of the trunk. This species had been assigned to different genera, such as Clavellopsis Wilson, 1915, Isobranchia Heegaard, 1947, and Neobrachiella Kabata, 1979.

  • The occurrence and infection level of parasitic Copepod, Clavella adunca on the black rockfish, Sebastes melanops at the Hatfield Marine Science Center Aquarium were studied. C. adunca was usually found on the base of fins, preferably on the pectoral fins. Seven specimens of black rockfish, Sebastes melanops were collected from Oregon Coast Aquarium. Copepods of ten Clavella adunca were present as ectoparasites attached to the fins in the black rockfish. The prevalence and relative density of Clavella adunca were 28.6% and 1.4 respectively. It is considered that the tissue of the fin membrane offers the most favorable conditions toy the attachment of C. adunca.

  • 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.

  • Ergasilus zacconis (Yamaguti, 1936), the copepod parasite originally named as Pseudergasilus zaconnis, is redescribed based on the specimens newly collected from the freshwater fish Zacco platypus (Temminck and Schlegel) from Japan. Some errors appearing in the original description are emended. An explanation for the generic position of this species is given.

  • Two species of the copepod parasite were observed from two marine fishes in Korea. A siphonostomatoid copepod Neobrachiella incurva (Shiino, 1956) (Lernaeopodidae) and a cyclopoid copepod Peniculus ostraciontis Yamaguti 1939 (Lernaeidae) were found on the gills of Halichoeres poecilopterus and the fins of Sebastes schlegeli, respectively. The most distinct features of N. incurva are bipartite of maxillule, 2 ventro-posterior processes and conical genital process. P. ostraciontis is very distinguishable in the body shape, antenna, and fused trunk. Both species of copepods are newly observed from the Korean waters.

  • Seven specimens of Sebastes melanops, black rockfish and three of S. maliger, quillback rockfish, were collected from Oregon Coast Aquarium during the period of September 19 to November 5, 2001 and examined for parasites. One monogenean helminth species and parasitic copepod species were recorded from black and quillback rockfishes, respectively. A total of 26 parasites were collected: 16 Microcotyle sebastis from the gill filaments of black and quillback rockfishes and 10 Clavella adunca were found in the fins of black rockfish. The prevalence of Microcotyle sebastis was 40.0%, and intensity of infection was 2.0(1-11). With regard to Clavella adunca, the prevalence and intensity were 20.0% and 1.4(2-8), respectively.
