  • 불가사리에 공생하는 요각류가 북태평양에서는 단 4종이 기록되어 있을 뿐이다. 공생성 요각류를 채집하기 위하여 한국산 불가사리를 조사한 결과 요각류 2종이 채집되었다. 이들은 Synstellicola 속에 속하는 1신종과 Scottomyzon gibberum으로서 이들을 기재 또는 재기재한다. S. gibberum은 북대서양에서만 발견되어지던 종으로서, 한국 해역에서는 여러가지 불가사리에 공생하고 있으며 한국내 분포범위가 넓은 것으로 밝혀졌다.

  • A new species of harpacticoid copepod Alteuthoides affinis associated with the sponge Callyspongia elegans (Thiele) was collected from offshore waters of Cheju Island, Korea, and is described with illustrations. In this genus, only one species, A. kootare Hicks, has been known to occur in association with an hexacnellid sponge from New Zealand. The new species is similar to A. kootare in the general morphologies such as the shape of body, oral appendages, and thoraxic legs. However, it can be separated from A. kootare by the expanded genital double semite, P1 exopod bearing only one claw without reduced accessary nail, and acute rostrum.

  • Three new copepod species of Anthessius are described as associates of mollusks. Anthessius tuberculatus n. sp. associated with the bivalve Asaphis violascens (Forsskal in Niebuhr, 1775) in Kosrae, Micronesia bears a pair of dorsal tubercles on the fifth pedigerous somite. Anthessius rarus n. sp. is associated with the aplysiid gastropod Dolabella auricularia (Lightfoot, 1786) in Bohol, the Philippines and has elongate caudal rami which are about 5.2 times as long as wide. Anthessius cucullatus n. sp. associated with the aplysiid gastropod Aplysia kurodai Baba, 1937 in Korea has a hood-like dorsal expansion on genital double-somite of the female.

  • This study selected the optimal microalgal species for mass culture of a brackish water copepod Paracyclopina nana. Fifteen microalgal species were tested to examine nauplius production and the survival and maturation of brood females. Total and daily nauplius production were highest in P. nana fed Tetraselmis suecica followed Isochrysis galbana, Dunaliella tertiolecta, and Phaeodactylum tricornutum. With a monospecific microalgal diet, the total density was highest with P. nana fed I. galbana, at 63.3 inds./mL. With a mixed microalgal diet, the total density of P. nana fed T. suecica+I. galbana was higher than that fed other mixed diets, although there was no difference between a monospecific diet of I. galbana and a mixed diet of T. suecica+I. galbana. Examining the fatty acid composition of P. nana, the eicosapentaenoic acid (EPA) was highest in P. nana fed T. suecica at 5.4% while the docosahexaenoic acid (DHA) content was highest I. galbana diet at 31.9%. Although no DHA was detected in T. suecica, P. nana fed this microalgal species had a high DHA composition of 24.3%. We suggest that the optimal microalgal species for the mass culture of P. nana is T. suecica which is easy to culture on masse and has a high linolenic acid content.
