The developmental stages of the sea louse Lepeophtheirus elegans (Copepoda: Caligidae) are described from material collected from marine ranched Korean rockfish, Sebastes schlegelii. In L. elegans, setal number on the proximal segment of the antennule increases from 3 in the copepodid to 27 in the adult. Using the number of setae as a stage marker supports(More)
The compartment model POSEIDON-R was modified and applied to the Northwestern Pacific and adjacent seas to simulate the transport and fate of radioactivity in the period 1945-2010, and to perform a radiological assessment on the releases of radioactivity due to the Fukushima Dai-ichi accident for the period 2011-2040. The model predicts the dispersion of(More)
Monogeneans (Platyhelminthes) mostly parasitize on fins, skin and gills of fishes. In Korea, the study on monogeneans is limited, although, fishes are frequently encountered with severe infection of monogeneans. Hence, some of ranched and wild fishes were collected from Tongyeong marine living resources research and conservation center, southern part of(More)
Fat greenling (Hexagrammos otakii) is an important commercial fish in the Northwestern Pacific, being distributed along the coastal waters of the East/Japan Sea and the Yellow Sea. To investigate population genetic structure and demographic history of this species, one hundred and fifty five individuals were collected from five localities in the(More)
The complete mitochondrial genome of sea urchin Hemicentrotus pulcherrimus (A. Agassiz, 1863) is determined. The genome is a circular molecule of 15,705 bp in length and the gene content and order are identical to those of other strongylocentrotid species. Lengths of all protein coding genes (PCGs) are identical to those of M. nudus. S. droebachiensis and(More)
The seasonal occurrence and habitat of two parasitic copepods, Peniculus minuticaudae (Shiino, 1956) and Peniculus truncatus (Shiino, 1956) (Siphonostomatoida, Pennellidae) infecting the fins of black scraper Thamnaconus modestus and Korean rockfish Sebastes schlegelii, respectively were investigated. The fishes were collected from Tongyeong marine living(More)
The complete sequence of mitochondrial DNA of a mottled skate, Raja pulchra was sequenced as being circular molecules of 16,907 bp including 2 rRNA, 22 tRNA, 13 protein-coding genes (PCGs), and an AT-rich control region. The organization of the PCGs is the same as those found in other Rajidae species. The nucleotide of L-strand is composed of 29.8% A, 28.0%(More)
Sebastes vulpes is considered a valid species despite the presence of extensive hybrids. To obtain the basic genetic intraspecific structure, we analyzed the complete mitogenome of S. vulpes using next-generation sequencing. The complete mitogenome was 16,462 bp in length containing 13 protein-coding genes (PCGs), 2 rRNAs, 22 tRNAs and 1 control region. The(More)
Three parasitic copepods (Siphonostomatoida) belonging to three different genera were recovered from marine fishes of Iraq, and are listed here as new records. The sea lice Caligus epinepheli Yamaguti, 1936 (Caligidae) was collected from the Japanese threadfin bream, Nemipterus japonicus (Bloch). It had been frequently reported from teleost fishes around(More)
Caligid copepods (Crustacea) known as sea lice are pests of cultured fish, causing serious diseases and economic losses in fish aquaculture worldwide. One species, Caligus sclerotinosus Roubal, Armitage & Rohde, 1983 (Caligidae), is considered a serious pest of the highly prized red seabream Pagrus major (Temminck and Schlegel, 1843) (Sparidae) cultured in(More)
