초록
전세계의 담수역에 널리 분포하는 Daphnia나 Moins와 같은 담수산 물벼룩은 잉어, 붕어, 금붕어와 같은 담수어의 종묘 생산과정에서 먹이 생물로서 널라 이용되고 있다. 그러나, 해산어의 종묘 생산 과정에서는 안정 배양, 대량 배양이 어렵다는 이유로 로티퍼나 알테미아 이외에 널리 이용되는 먹이 생물은 거의 없다. 이 연구에서는 해산 물벼룩보다는 비교적 배양이 용이한 기수산물벼룩 D. celebensis의 배양 용기의 크기가 안정배양에 미치는 영향을 검토하였다. 종 보존 배양 수준의 40ml 배양에서는 16일간의 배양 기간중 14일째에 최고 밀도가 3.416
Cladocera are important food organism for seed production of finfishes. freshwater cladocera such as Daphnia and Moina are well known food organisms for the larval rearing of freshwater fishes and are easy for mass culture. However, mass culture technique for marine cladocera are not yet developed, The only mass produced food organisms available these days for the larval production of marine finfishes are rotifer and Artemia. An estuarine cladoceran, Diaphanosoma celebensis, has a high possibility of being used as a food organism for the larval rearing of marine finfishes because this species is much easier to mass culture than marine ones. Therefore many studies are needed for this species. In this study, the effects of the volumes of culture container, 40, 1,500 and 15,000 ml, on the stable production of this species were tested and results are as follow: The maximum densities of this species in each of the culture volumes were reached after 14 days in 40 ml, 12 days in 1,500 ml, and 21 days in 15,000 ml with values of 3.4
