Abstract
The common harpacticoida copepod species Tigriopus japnnicus was often obseued in the mass culture of marine rotifer tanks of sea farming stations. In this study, we investigated the co-existing effect of T. iaponicus to the rotifer Brachionus rotundiformis population growth. The culture conditions as temperature, salinity, culture volume, photo period, culture period and observation interval were 25{\circ}C, 22ppt, 40ml, 12L:12D, 16 deys$ and every two days during the experimental period, respectively. Nannochloropsis oculata was used as the food for the two testing organisms. After counting the growth of rotifer and copepod, they were transferred to new culture tank with N. oculata at the density of
이 연구에서는 로티퍼 B. rotundiformis의 대량 배양조에서 흔히 혼재가 관찰되는 코페포다 T japonicus가 배양을 목적으로 하고 있는 로티퍼 B. rotundiformis의 증식에 어떠한 영향을 미치는지 알아보았다. 실험에 사용한 로티퍼와 코페포다는 로티퍼의 대량 배양조에서 순수 분리 후 단일종 배양하던 것이다. 배앙 조건은 현장의 배양환경과 되도록 일치하도록 하였으며, 먹이는
