摘要
本文以发育到第Ⅳ期的乌苏里白鲑鱼卵巢为材料，利用胰蛋白酶使固着在卵巢上的卵粒脱离下来，并研究了不同温度、盐度和胰蛋白酶浓度对鱼卵分离速度和效果的影响。结果表明，当温度为３７℃，盐度为２０％时，胰蛋白酶对固着在卵巢上的卵粒具有分离作用，分离速度为８分钟．分离率达到１００％，破损率为０．与原始搓制法相比；出籽率提高２５％以上。
by using trypsin the roregonus Ussuriensis eggs Were divided successfully form its Ⅳ ovaries.The affection of temperature Salinty and trypsin comcentration were observed,When temperature Changed to 37℃ and salinity Changedto 20%, the divided results showed to be better,the divided rat.reached 100%,It cost only 8 minute.By the way,theSpewning rate Might mcreased 25% compared With.original method.
