  • The feeding habits of spearnose grenadier (Coelorinchus multispinulosus) were studied using 361 specimens collected from January to December 2005~2006 in the coastal waters off Gori, Korea. The size of C. multispinulosus ranged from 1.5 to 8.5 cm in anal length (AL). C. multispinulosus was crustacean feeder that consumes mainly consumed shrimps and amphipods. Its diet also included small quantities of copepods, mysids, cumaceans, stomatopods, crabs, polychaetes and fishes. C. multispinulosus mainly consumed shrimps in all size classes and seasons except the smallest size class in summer which mainly consumed amphipods. Smaller individuals secondly consumed amphipods, copepods and mysids, and the portion of these prey items in the total diet decreased as body size.

  • A taxonomic study of the family Macrouridae was conducted using fish collections deposited in the Department of Biology, Chonbuk National University, Chonju, Korea and the East Sea Fisheries Research Institute, Korea. Among these collections were specimens of four species belonging to the genera Coryphaenoides and Coelorinchus: Coryphaenoides marginatus, C. microps, Coelorinchus (Abyssicola) macrochir, and C. formosanus. These specimens represent the first records of the species from Korean waters and from the East Sea (Japan Sea). Only four species (Coelorinchus longissimus, C. multispinulosus, C. japonicus, and C. parallelus) had previously been recorded from the East Sea. The Korean names "Keun-nun-gin-ga-si-min-te" (for Coryphaenoides marginatus), "Jak-eun-nun-gin-ga-si-min-te" (for C. microps), "Gin-pal-kko-ri-min-te" (for Coelorinchus macrochir), and "Ta-i-wan-kko-ri-min-te" (for Coelorinchus formosanus) are herein given to these species.

  • We investigated temporal and depth-related variation in species composition and abundance of the fish assemblage in the southern East Sea. Fish samples were collected seasonally between 2007 and 2008 using a demersal trawl off the southern coast of Korea. We identified 59 fish species belonging to 41 families. The most frequently occurring species was Coelorinchus multispinulosus, followed by Lophius litulon, Acropoma japonicum and Apogon lineatus. The five most abundant species were A. lineatus, A. japonicum, Myctophum nitidulum, Engraulis japonicus and C. multispinulosus, accounting for 87.04% of the total number of individuals collected. The number of species, abundance and diversity fluctuated with sampling location and time. Permutational multivariate analyses of variance revealed that the assemblage structure was influenced by year, season and water depth, with season being the main indicator. These changes were visually emphasized using non-metric multidimensional scaling ordination plots. Fluctuations in assemblage structure were due to differential contributions of the dominant species.

  • The feeding habits of Scorpaena neglecta were studied based on an examination of the stomach contents of 478 specimens collected between January and December 2006 in the Coastal Waters off Busan. The specimens ranged from 9.0 to 23.5 cm in Standard length (SL). S. neglecta is a piscivore and consumes mainly teleosts such as Acropoma japonicum, Coelorinchus multispinulosus, Chaeturichthys stigmatias. Its diet also includes crabs, shrimps, cephalopod and stomatopod. Smaller individuals (<16 cm SL) consume mainly crabs and shrimps. The proportion of these prey items (crabs and shrimps) decreases with increasing fish size, and this decrease parallels the increased consumption of fish. The mean prey size sharply increases between 12 and 20 cm SL of S. neglecta size.
