  • In order to know the fauna of Korean Caprellidae, the authors examined the materials which were collected from many places of East Sea, South Sea and YelloW sea in 1955, 1964 and during the period from 1969 to 1975. Collections were made chiefly by hand with pincette at intertidal zones and with gill nets at subtidal zones. The results of the identification were found to be 11 species of Caprella of which the following 9 species were hitherto unrecorded from Korean waters. 1. Caprella californica Stimpson, 1857 2. C. danilevskii Czerniavski, 1868 3. C. decipiens Mayer, 1890 4. C. equilibra Say, 1818 5. C. kroeyeri De Haan, 1849 6. C. polyacantha Utinomi, 1947 7. C. scaura Templeton, 1836 8.

  • This study on the ampithoid gammarids in Korea was based on the materials collected in 32 localities , and deposited in the Department of Zoology, Seoul National University . Twelve species in three genera were identified and classified, of which following five species were new to science ; Ampithoe brevipalma Ampithoe Koreana, AMpithoe youngsanensis, Peramphithoe baegryeongensis, Peramphithoe namhaensis. Ampithoe shimizuensis Stephensen, 1944 was newly ranked as a subspecies - Ampithoe valida shimizuensis. Ampithoe ramondi Audouin, 1826 ,Peramphithoe tea (Barnard , 1965), Perzmphithoe orientalis (Dana, 1853) and Sunamphithoe plumosa Stephensen, 1944 are new records for Korea.

Changes in Feeding Habit and Body Composition of Black Sea Bream Acanthopagrus schlegeli Released in Eelgrass Zostera marina Bed (잘피밭 해역에 방류된 감성돔 Acanthopagrus schlegeli 치어의 식성 및 어체성분 변화)

  • Artificially-produced juvenile black sea bream Acanthopagrus schlegeli (total length $8.3{\pm}1.0\;cm$, body weight $11.2{\pm}4.2\;g$) were released in eelgrass, Zostera marina bed and their initial food organism and changes of body compositions were investigated for one month after release. Predation rates in fish sampled on 1st and 3rd days were 79%, increased up to 100% on 7th and 10th days, and then decreased on 30th days as 75%. Major prey organisms was composed of mainly Amphipoda and Gastropoda. Ratio of Amphipoda and Gastropoda in stomach were highest in fish sampled on 15th and 1st days after release, respectively. Crustacea and Algae were maintained about 20% during a sampling period. Visceral weight index (VWI) offish sampled 20th and 30th after release were significantly higher than that of initial. Carcass crude protein and lipid contents of released fish were showed significantly decreasing; however carcass n-3 HUFA composition was showed increasing tendency with the passage of time after release. Eelgrass bed was supposed to be helpful for the released fish to adjust their feeding habits and biochemical metabolism to the natural environment within a short period after release.

  • The community structure of macrobenthos was investigated around Sorido Island, southern coast of Korea between August 1996 and April 1997. Triplicate macrobenthic samples were taken seasonally at twelve stations in August and November 1996 and fourteen stations in February and April 19n by van Veen grab ($0.1m^2$). A total of 217 macrobenthic species were identified during study Period: 80 species were from polychaetes, 60 species from crustaceans, and 46 species from mollusks. The mean density of macrobenthos estimated $1,068 ind/m^2$, and polychaetes comprised $85\%$ of total density. The mean biomass was $110.2 g/m^2$, and echinoderms contributed to more than a half of the biomass. Major dominant species based on abundance were three polychaetes Tharyx sp., Lumbrineris longifolia, and Magelona japonica, which frequently occur in the coastal area enriched by organic pollution. The densities of the species were $582 ind/m^2$, $72 ind/m^2$, and $41 ind/m^2$, respectively. These species showed very low density in the offshore area. The study area was classified into four regions each sustaining specific macrofaunal assemblages by Bray-Curtis cluster analysis: a station group adjacent to the Kwangyang Bay and Yosu harbour and three station groups around Sorido Island. There were negative correlations between the concentration of PAHs in sediments and the abundance of Ampeliscidae spp. and Amphipoda. These results were discussed in terms of both environmental factors and distribution of benthic community.

  • Newly recorded cyproideid species of the genus Terepeltopes was collected from Korean waters. The monotyptic genus Terepeltopes erected with T. dolichorhunia Hirayama, 1983 was only known to be found at West Kyushu, Japan. In this study, the family Cyproideidae Barnard, 1974 is first recorded from Korea by the discovery of T. dolichorhunia, and we provide description and illustrations of this species.

  • A terrestrial talitrid amphipod, Platorchestia japonica (Tattersall, 1922), has been recorded for the first time from Korea. This species was collected from riversides (Han River, Bukhan River and Hantan River) in Korea. Descriptions of diagnostic characters of the species are provided in the text. A key to the four species of Korean Platorchestia is also provided.
