摘　　要：利用超声波检查仪对人工养殖西伯利亚鲟的性别及性腺发育进行超声波扫描,并利用微创手术检查和组织学观察法来验证超声波对西伯利亚鲟性别及发育时期扫描的鉴定结果。通过对比研究表明:超声波方法对西伯利亚鲟性别鉴定的准确率较高,对2～5龄雌性鉴定的准确率为95%,对雄性鉴定的准确率为87%。超声波技术鉴定性腺发育的准确率随性腺的发育而提高,鉴定早期性腺(Ⅰ～Ⅱ期)发育的准确率(65.25%)低于对晚期性腺(Ⅲ～Ⅴ期)发育鉴定的准确率(88.65%)。超声波技术鉴定西伯利亚鲟性别及性腺发育速度较快,根据鱼的发育状况,平均每尾鱼所用的时间约30s。The sex and gonad development in cultured Acipenser baerii was scanned by ultrasonic scanning. The results of sex and development stages of scanned A. baerii were identified by Minimally Invasive Surgical technique and histological examination. By comparative study, the results showed that there was higher accuracy of sex identification in A. baerii by ultrasonic method, the accuracy of identification in female was 95% higher than that in male, which was 87%. Success of gonad development identification by ultrasonic method was decided by gonad development, the accuracy of gonad development in early stages （ stages Ⅰ - Ⅱ ） Was 65.25% lower than that in later stages （ stages Ⅲ - Ⅴ ）, which was 83.65%. The speed of sex identification using ultrasonic technology was faster, according to the developmental status of A. baerii, the duration time was only 30 s.
