자주복(Takifugu rubripes) 정자의 액상보존을 위한 기초자료를 얻고자, 수조사육한 전장 43.5-45.1 cm, 체중 1.7-2.0 kg의 2-3년생 자주복 수컷을 재료로 하여, 정자의 액상보존 효과를 연구하였다. 희석액으로 marine fish ringer solution과 1% NaCl을 사용하여 7일간 보존하였을 때, SAI와 정자의 생존율이 각각 1.7과 $59.0\pm1.5%,\;1.6$과$\;56.7\pm6.2%$로 가장 높았다. 정자를 3-5배로 희석하여 보존하였을 때, 가장 높은 SAI와 정자의 생존율을 보였으며, 보존온도로는 0- 5$^{\circ}C$가 적절하였다. SAI와 정자의 생존율을 높이기 위한 항생제로는 neomycin (800 ppm)이 효과적이었다.

Abstract

Condition for fresh storage of tiger puffer in the liquid state were investigated in several experiments. When marine fish ringer solution and 1% NaCl were used as the diluent for the short-term preservation method, spermatozoa activity index (SAI) and survival rate showed the best result among the various diluents tested. The dilution rate for the shortterm preservation of spermatozoa was suitable between 3 and 5 times with the 1% NaCi diluent. The appropriate range of temperature for the short-term preservation showed between 0 and $5^{\circ}C$. In order to keep high SAI and survival rate of spermatozoa, antibiotic addition (800 ppm neomycin) could be suggested. These results indicated that the short-term preservation method could be employed in tiger puffer spermatozoa.
