Abstract

To obtain fundamental data for sperm cryopreservation in river puffer (Takifugu obscurus), the proper conditions of cryopreservation were investigated. In the sperm cryopreservation of river puffer, marine fish Rinser's solution (MFRS) was found to be good diluent and dimethyl sulfoxide (DMSO) was proved to be superior to glycerol as a cryoprotectant. The highest fertilization rate was achieved when river puffer sperms were cryopreserved with MFRS adding 5％ DMSO.

황복(Takifugu obscurus) 정자의 냉동보존을 위한 기초자료를 얻고자, 냉동보존 조건에 관한 연구를 수행하였다. 황복 정자의 냉동보존을 위한 희석액으로는 다른 여러 가지 희석액에 비해 MFRS가 가장 적합하였으며, 동해방지제로는 DMSO가 glycerol에 비해 효과가 좋은 것으로 나타났다. MFRS를 희석액으로 하고 동해방지제인 DMSO를 최종농도가 5%되도록 첨가하여 정자를 냉동보존하였을 때, 해동정자의 수정률은 74.3±7.5%로 가장 보존효과가 좋았다.
