Early zoeal stages of two snapping shrimps Alpheus digitalis De Haan, 1850 and Alpheus japonicus Miers, 1879 are described and illustrated in detail for the first time based on the laboratory-reared materials. The first zoeas of Alpheus are more related to those of Vexillipar than to Athanas, Automate, and Synalpheus by having rostrum absent, the tip of the endopod of the antenna with a long plumose seta as well as a spine, the endopod of the maxilla with a basal and two terminal setae, the exopod of the maxilla shorter than the endopod, and the endopod of the second maxilliped with a seta on the proximal segment. A list of larval descriptions and described stages of the Alpheidae reported from Indo-West Pacific waters are included.

First zoeas of Alpheus albatrossae (Banner, 1953) are described and illustrated for the first time, based on laboratory-hatched zoeas from a female collected in Ulleung-do Island, eastern Korea. The first zoeas of A. albatrossae can be distinguished from those of seven known species of Alpheus (A. brevicristatus, A. digitalis, A. heeia, A. japonicus, A. lobidens, A. richardsoni, and A. sudara) from Korea by having 6-segmented scale of the antenna and the endopod of the first maxilliped with four terminal setae.

The snapping shrimp Alpheus bisincisus is redescribed on the basis of nine specimens collected in southern Korea. This species is readily distinguished from the other reported species of the Edwardsii group of Alpheus from Korea (A. heeia, A. hoplocheles, A. japonicus, A. lobidens, A. malabaricus, A. pacificus, A. richardsoni, and A. sudara) by having the rostrum and rostral triangle on the carapace flattened dorsally and sharply demarked, and by the presence of overhanging orbitorostral grooves.

2003년 8월 3일부터 8월 5일까지 전라북도 군산시에 속한 고군산군도의 5개 섬을 대상으로 조간대 및 조하대와 어선의 그물에서 채집된 십각류를 관찰한 결과 새우류 2과 4종, 집게류 4과 9종, 게류 11과 29종으로 모두 17과 42종이 동정, 분류 되었다. 이 가운데 새우류 2종, Athanas sp., Alpheus sp.는 한국미기록종이었으며, 이들을 포함하여 10과 20종-새우류 1과 2종, 집게류 3과 6종, 게류 6과 12종-이 고군산군도 해역에서 처음 보고 되는 종들이었다. 따라서 과거 이 지역에서 보고 된 19과 52종에 10과 20종을 추가하여 총 72종이 보고 된다. 조사된 십각류 중에서 게류가 11과 29종으로 가장 다양했으며, 생물량은 새우류에서 줄새우아재비 [Palaemon(Palaemon) serrifer], 게류에서 칠게 (Macrophthalmus japonicus)와 엽낭게 (Scopimera globosa), 집게류에서 가시투성 어리게 (Hapalogaster dentata)가 가장 많았다.

본 연구는 대한민국 온라인 시장에서 판매되는 48개의 새우 제품의 종판별 및 제품 표시 사항 일치 여부를 조사하였다. 사용 원재료의 종 판별을 위해 cytochrome c oxidase subunit I 유전자의 염기서열을 분석하여 NCBI GenBank 및 BOLD system 데이터베이스에 등록된 생물종의 염기서열과 비교하였다. 또한 계통분석을 수행하여 동정된 새우종을 추가로 검증했다. 종판별 결과 총 16종[흰다리새우(Penaeus vannamei, Whiteleg shrimp or Pacific white shrimp), 북쪽분홍새우(Pandalus borealis, Alaskan pink shrimp), 그라비새우(Palaemon gravieri, Chinese ditch prawn), 돗대기새우(Leptochela gracilis, Lesser glass shrimp), 얼룩새우(Penaeus monodon, Giant tiger prawn), 아르헨티나붉은새우(Pleoticus muelleri, Argentine red shrimp), 산모양깔깔새우(Metapenaeopsis dalei, Kishi velvet shrimp), 태평양난바다곤쟁이(Euphausia pacifica, Isada krill), 가시배새우(Lebbeus groenlandicus, Spiny lebbeid), 꽃새우(Trachypenaeus curvirostris, Southern rough shrimp), 진흙새우(Argis lar, Kuro shrimp), 가시발새우(Metanephrops thomsoni, Red-banded lobster), 깔깔새우(Metapenaeopsis barbata, Whiskered velvet shrimp), 긴발딱총새우(Alpheus japonicus, Japanese snapping shrimp), 대하(Penaeus chinensis, Fleshy prawn), 긴뿔민새우(Mierspenaeopsis hardwickii, Spear shrimp)]이 확인되었으며, 흰다리새우(n=22, 45.8%)가 가장 큰 비중을 차지하였다. 일반명 '새우'를 포함하는 35개 제품(72.9%)에서 표시사항과 불일치를 나타내었으며, 일반명(n=30)을 제외할 경우 불일치율은 10.4%로 낮아졌다. 가공 정도별 불일치율은 다중 가공 제품(n=25, 89.3%)이 단순 가공 제품(n=10, 50%)보다 높은 비율을 보였다. 원산지별 분석 결과 특정 국가와 불일치율과의 상관성은 확인할 수 없었다. 본 연구 결과는 향후 새우 제품의 모니터링 수행 및 새우의 국명 표시 개선을 위한 기초자료로 쓰일 수 있을 것이다.

The comparative feeding ecology of greenling Hexagrammos otakii and Schlegel's black rockfish Sebastes schlereli populations was investigated in the Jangbong tidal flat near Incheon, Korea. Monthly samples were taken using a modified otter trawl from November 1999 to January 2001. The stomach contents of 124 greenling and 115 Schlegel's black rockfish were analyzed. The diet of H. otakii was dominated by the amphipods Gammaropsis iaponicus, Caprella scaura, Isaeopsis sp. and Monocorophium acherusicum, the shrimps Latreutes mucronatus and Alpheus japonicus, the mysid Neomysis orientalis and the bivalve Mytilus edulis. In contrast, S. schlegeli mainly fed on the mysids N. orientalis, N japonica, and N. awatschensis, the shrimps Exopalaemon carinicauda, A. japonicus and L. mucronatus, and the fish Pholis fangi and unidentified gobiids. A comparison of the frequency and abundance of food items showed that crustaceans (e.g. amphipods, mysids and shrimps) were important foods for both species. Their main dietary components, however differed which is probably due to differences in the spatial distribution of the two species and their prey items. In conclusion, greenling and Schlegel's black rockfish, despite being sympatric on a tidal flat have distinct food habits and low dietary overlap (Schooner's index: 0.1). These results indicate, to some extent, resource partitioning for the maximum utilization of available foods in the tidal flat.

Food habits of the gavelin goby Acanthogobius hasta and the fine spot goby Chaeturichtys stigmatias populations were investigated in the Jangbong tidal flat near Incheon, Korea. Samples were taken monthly from November 1999 to January 2001. The gut contents of 248 gavelin gobies and 139 fine spot gobies were analyzed. The diet of the gavelin goby was dominated by the gammaridean amphipod Chitinomandibulum emargicoxa, the crabs Macrophthalmus japonicus and Ilyoplax pingi, the shrimp Exopalaemon carinicauda, the bivalve Raetellops pulchella and the macro-algae Porphyra tenera. On the other hand, the fine spot goby mainly feed on the shrimps Crangon affinis, Latreutes mucronatus, E. carinicauda and Alpheus japonicus, the gammaridean amphipods C. emargicoxa and Synchelidium miraculum, and the bivalve R. pulchella. A comparison between frequencies of occurrence and abundance of food items in the gut showed that crustaceans (gammaridean amphipods, crabs and shrimps) and bivalves were important foods for the two gobies. However, the main components of the gut contents were different between two species, though this was probably due to differences in spatial distribution patterns of gobies and their prey items. In conclusion, both the gavelin goby and the fine spot goby, despite being the related species and co-inhabiting the similar part of the tidal flat, had quite distinct food habits and low dietary overlap (Schoener's index: 0.4). These indicated that the two gobies are or were partitioning resources in space and time for maximum uitilization of available food.

Species composition and seasonal variation of decapod crustacean assemblage in Hampyeong Bay, Korea were examined. Sampling was monthly made by a shrimp trawl between March 2003 to February 2004. A total of 39 species of 20 families were collected. Of these, Latreutes planirostris, Palaemon gravieri, Parapenaeopsis tenella, Exopalaemon carinicauda, Charybdis japonica, Trachysalambria curvirostris and Palaemon macrodactylus were dominant species comprising $84.3\%$ of the total number of individuals. Charybdis japonica, P. gravieri, Oratosquilla oratoria, E. carinicauda, T curvirostris, Metapenaeus joyneri and P. tenella represented $90.6\%$ 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 summer. Cluster analysis, based on monthly abundance data of the 14 most common species, showed that the species were separated into three different groups. Group A composed of Leptochela gracilis, Alpheus japonicus, Crangon uritai, P. macrodactylus, E. carinicauda, P. gravieri, O. oratoria, C. japonica, which were year round residents, group B M. joyneri, T. curvirostris and P. tenella, which were abundant in summer, and group C Crangon hakodatei, Latreutes anoplonyx and L. planirostris, which were abundant in winter. Principal component analysis revealed that seasonal variation in the decapod crustacean assemblage was attributed to the abundance of temporal species such as penaeid shrimps, which were abundant in summer, due to seasonal variation of water temperature and reproductive pattern.
