在日本传统捕鱼中使用的日本鸬鹚是野生的，它们的性别不能从外表上确定。分子性别测定的基础上CHD1Z和CHD1W内含子之间的大小差异的适用性，证实了在男性和女性的日本鸬鹚的性别已确定的病理尸检。一名鸬鹚捕鱼师傅饲养的21只性别不明的鸟全部被鉴定为雄性。分子性别鉴定方法将为野生日本鸬鹚的性别差异提供有价值的信息，包括驯服性，可训练性，行为和捕鱼能力，以及未来的人工繁殖试验。
The Japanese cormorants used in traditional fishing in Japan are wild derived and their sex cannot be determined from their appearance. Applicability of molecular sex determination based on the size difference between CHD1Z and CHD1W introns was confirmed in male and female Japanese cormorants whose sexes had been ascertained by pathological autopsy. All of 21 birds of unknown sex reared by a cormorant fishing master were identified as males. The molecular sexing method will provide valuable information on sex differences of wild Japanese cormorants, including tameness, trainability, behavior and fishing capability, as well as for future trials involving artificial reproduction.
