  • Copepod is useful live food organism in the larval rearing. However of fin fish, culcures of copepod species (Specially calanoida and cyclopoida) were very difficult under artificial management conditions. In this study, we report successful culture of a free swimming cyclopodia copepod species (Apocyclops sp.) by easily baker's yeast as food. The maximum culture density of Apocyclops sp. was observed 11,200±2,660 ind/ℓ during the 30 days culture periods in the 1.5ℓ culture tanks. The nauplii were growth up maximum density 6,400±432 ind/ℓ on day 16th. The number of egg carring female was observed maximum density (666.7 ind./ℓ) of two times after 6days and 28 days of initial culture.

  • 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.

  • Four new species of the genus Panjakus (Copepoda, Cyclopoida, Anchimolgiae) are described as associates of scleractinian corals from the eastern Ceram, the Moluccas: P fastigatus and P. parvipes from Hydnophora microconos (Lamarck), and P. saccipes and P. iratus from Platygyra ryukyuensis Yabe and Sugiyama. A key to 11 known species of Panjakus is provided.

  • A new species of the genus Farranula Wilson, 1942 (Cyclopoida, Corycaeidae) is described based on both sexes collected off Chuuk Island in Micronesia (West Central Pacific). The new species F. dahlae differs from its close congener F. gibbula (Giesbrecht, 1891) in the following combination of characters in both sexes: body length is longer, length to width ratio of caudal rami is larger, basal element of maxilliped is distinctly longer, and terminal spine to distal segment ratio of P4 is smaller; while in females, lateral margins of fourth pedigerous somite are extended to mid-region of second urosomal somite, maximum width of the second urosomal somite is located at middle region in dorsal and lateral views, and length ratio of caudal seta III to seta V is much larger; and in males, sharply contracted portion of second somite is located at two-thirds distance from anterior margin. Some additional morphological details of F. gibbula are given and a key to species of the genus Farranula is provided.

  • Twenty-two new species of poecilostome copepods associated with marine invertebrates are described from the West Indies, Madagascar, and Pacific coast of Panama. They are Anthessius nosybensis n. sp. and Discanthessius solitarius n. gen. n. sp. in the Anthessiidae; Cemihyclops tenuis n. sp., Hemicyclops tripartitus n. sp., H. humesi n. sp., H. magnus n. sp., and Leptinogaster minuta n. sp. in the Clausidiidae; Schedomolgus crenulatus n. sp. and S. parvipediger n. sp. in the Anchimolgidae; Kelleria multiovigera n. sp. in the Kelleridae; Lichomolgus angustus n. sp. and L. fusiformis n. sp. in the Lichomolgidae; Pseudanthessius acutus n. sp., P. asper n. sp., and Tubiporicola pediger n. gen. n. sp. in the Pseudanthessiidae; Acanthomolgus tenuispinatus n. sp. and Notoxynus lokobensis n. sp. in the Rhynchomolgidae; Eupolymniphilus occidentalis n. sp. and E. brevicaudatus n. sp. in the Sabellephilidae; Enalcyonium robustum n. sp. and E. grandisetigerum n. sp. in the Lamippidae; and O. binoviger n. sp. in the Myicolidae. Hemicyclops geminus Stock is synonymized with H. columnaris Humes which is now known as a species of amphi-American distribution. Hemicyclops columnaris Humes, Modiolicola trabalis Humes, and Ostrincola breviseti Ho and Kim are redescribed.

  • 국내 지하수의 지속적인 개발을 위한 훌륭한 방안이 될 수 있는 Stygofauna를 이용한 biological indicator system 개발을 위해 국내 지하수를 대표할 수 있는 국가지하수관측망 약 200여 개소를 선정하여 국내 지하수 미소생물 분포를 조사하였다. 전국의 지하수 생물 채집 결과, Cyclopoida(41.4%)가 우리나라 지하수 생태계에서 가장 전형적인 동물로 나타났으며, 암반대수층보다 에너지와 유기물이 충분한 충적대수층에서 동물의 밀집도가 두 배 가량 높게 나타났다. 생물 분포 또한 충적대수층과 암반대수층이 약간 다르게 나타났다. 권역별 동물 개체수 비교 결과, 금강권역에 비해 영산강과 낙동강권역은 종과 개체수가 적게 나타났다.
