초록

원생동물 섬모충의 한 종인 Euplotes는 해산어 종묘생산시설의 로티퍼 대량배양수조에서 혼재생물로서 매우 자주 관찰된다. 그들은 로티퍼에게 먹이로 첨가되는 농축 상태의 먹이(미세조류)를 중간에서 가로채어 빠른 속도로 증식하면서 로티퍼의 증식을 방해한다. 더불어 이때 형성된 배양수조내의 세균상은 로티퍼의 전멸을 초래하기도 한다.

Common co-existing organism Euplotes (Ciliate, Protozoa) well often observed in the rotifer mass culture tank of marine fish larval rearing stations. Ciliate protozoa (Euplotes) competed to condensed food (micoralgae, Nannochloropsis oculata) with rotifer (Brachionus rotundiformis). As results, rotifer density was rapidly decrease, and what is more, the rotifer was wiped out by dominant bacteria species at that time.
