Abstract

Four cyclopoids were tested for laboratory culture. Among these animals, only Eucyclops serrulatus was successfully cultured in the laboratory. Under the laboratory culture condition, nine kinds of diets were tested for the suitability of nauplius development. Development and reproduction of E. serrulatus were also investigated. Chlamydomonas reinhardii was the only one which could induce complete development from nauplii to adults. It was found that E. serrulatus had relatively short generation time, could produce lots of progenies, and could be handled easily, allowing to obtain many individuals during a short period. With these characteristics, this species may be a candidate for a good test organism for evaluating freshwater pollution.

실험실에서 배양을 하기 위해 담수에서 광범위하게 서식하는 4종류의 검물벼룩목 요각류를 실험하였다. 이 중 Eucyclops serrulatus만이 성공적으로 배양되었다. 다음으로 9가지 먹이 조건 중 어떤 것에서 유생발달이 정상적으로 이루어지는 지를 살펴보았다. 이렇게 선정된 실험실 배양 환경하에서 E. serrulatus의 생식과 성장을 관찰하였다. 배양 방법이 간단하여 짧은 시간 동안 많은 순수배양된 개체들을 얻을 수 있다는 점으로 볼 때 Eucyclops serrulatus는 담수 생태계의 오염을 측정하는데 bioindicator 생물로서 응용 가능성이 크다고 할 수 있겠다.
