超声成像技术在大西洋鲑早期性别及发育期鉴别的应用研究
The application of ultrasound imaging technology in the early determination of sex and gonadal development in Atlantic salmon (Salmo salar)
摘要
Abstract
Cultured Atlantic salmon (n = 273), aged 1–2 years were examined using an ultrasound device (KX-5100;with a 7.5-MHz linear probe) from April to December of 2012. Following ultrasound scanning, necropsy and sam-pling were performed and histological specimens were prepared to independently confirm ultrasound determina-tions of sex and developmental stages. Results showed that, on average, the accuracy of identification using ultra-sound imaging technology was 86% in Atlantic salmon, and there was a higher accuracy of sex identification of females (93%) than males (81%). In addition, the accurate identification of stages Ⅲ, Ⅳ and Ⅴ in the ovaries of female fish were 87%, 92% and 100%, respectively, while the accurate identification of stages Ⅱ, Ⅲ, Ⅳ and Ⅴin male testes were 64%, 71%, 86% and 84%, respectively. Overall, the accuracy of gonadal development in early stages (i.e., stages Ⅱ and Ⅲ) was lower (75%) than that of the later stages (i.e., stages Ⅳ and Ⅴ), which was 89%.关键词
