As a result of the faunistic study on the subterranean cyclopoid copepods, four species of three genera in the family Cyclopidae are reported from nine limestone caves and a lava tube in South Korea: Megacyclops magnus (Marsh, 1920), Acanthocyclops orientalis Borutzky, 1966, A, robustus (Sars, 1863) and Diacyclops suoensis Ito, 1956, all of them new to Korean fauna. This paper deals with the taxonomic accounts and illustrations of the four species with the redescription of A. orientalis. This is the first taxonomic study on the cave-dwelling cyclopoid copepods from Korea.

The cyclopoid specimens collected from various freshwater habitats at 141 locations in South Korea during the period from May 1983 to May 1989 are identified into 25 species or subspecies of 12 generain family Cyclopidae, and the seventeen species newly reported from Korea are redescribed and figured.

Two brackish cyclopoid species are reported mostly from the estuaries and salt marshes in the southern coast of Korea: Limnoithona sinensis (Burckhardt, 1913) and Apocyclops borneoensis Lindberg, 1954. The two species as well as the genera are newly added to Korean fauna. Herein, the redescription is provided with the systematic accounts and detailed illustrations of them.

요각류는n-3 HUFA의 함량이 풍부하여 동물먹이생물인 Artemia를 대체할 수 있는 먹이생물로서 이용 가능하다. 이러한 요각류를 먹이생물로 이용하기 위해서는 대량 배양이 성공적으로 이루어져야 한다. cyclopoid 요각류인 Paracyclopina nana는 부유성으로 성체의 크기가 500~60$\mu\textrm{m}$로서 Artmia nauplii(500$\mu\textrm{m}$)와 비슷하고, 요각류 Sinocalanus tenellus, Apocyclops royi, Tachidius triangularis, Nitoca lacustirs, Tigriopus sp.와 비교해서 개체 성장 및 군집성장에서 매우 높게 나타났다.

A new cyclopoid species belonging to the genus Acanthocyclops is described from several mountain springs in South Korea. This species is allied to A. kieferi species group in sharing 11-segmented antennules, but is, clearly distinguished from them by its single apical spine on the third endopodal segment of leg 4 and an extra spine on the distal segment of leg 5 in both sexes.

The productivity of cyclopoid copepod, Apocyclops royi fed by various diets (Isochrysis galbana, Tetraselmis suecica, Phaeodactylum tricornutum, concentrated freshwater Chlorella and baker's yeast) was investigated at tile different temperatures ($16-36^{\circ}C$) with different salinities (5-34 ppt). A. royi was cultured in 6 ml vessels (12 wells culture plate). Total production (188 inds.) and daily production (13.4 inds.) of nauplii by A. royi female at $32^{\circ}C$ were significantly higher than those of nauplii at the different temperatures (P<0.05). Development time from nauplii to copepodite and from nauplii to adult tended to increase with increasing water temperature up to 32. And total production (169 inds.) and daily production (9 inds.) of nauplii by A. royi female at 10 ppt were significantly higher than those of nauplii at the different salinities (P<0.05). The fastest development time from nauplii to copepodite and from nauplii to adult was observed at 10 ppt and 15 ppt, respectively (P<0.05). The highest total production of A. royi nauplii and fastest development time from nauplii to adult were obtained in females fed Isochrysis galbana (P<0.05). These results may indicate that the optimum culture temperature and salinity for A. royi are $32^{\circ}C$ and 10 ppt, respectively, and Isochrysis galbana is one of the suitable diets for this copepod.
