Two Hippolytid Shrimps(Crustacea: Decapoda: Caridea) from the Deepwater of the East Sea, Korea

Two hippolytid shrimps, Spirontocaris spinus(Sowerby, 1805) and Lebbeus unalaskensis(Rathbun, 1902) are described on the basis of material collected from the deepwater of the East Sea, Korea at 310-810 m. The former has been incorrectly known as Spirontocaris arcuata Rathbun, 1902 in Korea and the latter is a new member of the Korean fauna. Morphological and distributional accounts of these species are presented with illustrations.

First Record of the Genus Pagurixus (Crustacea: Decapoda: Anomura: Paguridae) from Hyung-ge Island, Southern Korea

A pagurid hermit crab, Pagurixus patiae collected from Hyung-ge Island, Busan, southern Korea is newly recorded into the Korean fauna. Pagurixus patiae is the only species of the genus recorded in Korea. Morphological descriptions of P. patiae are provided.

Seasonal variation of fish assemblage in Sacheon marine ranching , the southern coast of Korea

Species composition and seasonal variation of fish assemblage in Sacheon marine ranching, Korea were examined. Sampling was seasonally made by a shrimp trawl from February 2009 to November 2009. A total of 55 species were collected. Of these, five species was dominant species comprising 51.1% of the total number of individuals. Nine species represented 57.3% of the total biomass. While total abundance (number of individuals) was high in spring, total biomass and species richness (number of species) and diversity were high in autumn. Cluster analysis, based on seasonally abundance data of the 21 most common species, showed that the species were separated into 4 different groups. Group A composed of Pholis nebulosa, Pleuronectes yokohamae, Hypodytes rubripinnis, Hexagrammos otakii, Tridentiger trigonocephalus and Paracercis sexfasciata, which were year round residents, group B Congr myriaster, Leiognathus nuchalis, and Platycephalus indicus, which were abundant in autumn, group C Sillago japonica, Pseudaesopia japonica, Zoarces gilli, Pholis fangi, and Pleuronichthys cornutus which were abundant in spring, and group D Sillago sihama, Cociella sp., Johnius grypotus, Cynoglossus joyneri, Cynoglossus robustus, and Pennahia argentata, which were abundant in summer. Principal component analysis revealed that seasonal variation in the fish assemblage was attributed to the abundance of temporal species such as conger and sand smelt fishes, which were abundant in summer, due to seasonal variation of water temperature.

Age and Growth of Whitespotted Conger Conger myriaster in the Southern Coastal Waters of Korea

【Age and growth of whitespotted conger Conger myriaster were estimated using right sagittal otoliths from 495 fish collected from February, 2004, to January, 2005, in the southern coastal waters of Korea. Examination of the outer margin of the otoliths showed that opaque zones formed once a year and annual rings formed from April to June. The ages of the specimens examined ranged from 3 to 8 years. Whitespotted conger spawn from December to March. Allometry between preanal length and total weight can be expressed as
