大鲵自华中地区引进至华南地区,并驯养成功后,在特殊人工生态条件下,其性腺发育规律也随之发生改变。大鲵性腺成熟系数最大值,由大鲵自然产区的8月中旬提前到6月中旬至7月中旬。用大鲵周年性腺成熟积温推算,大鲵性腺成熟期亦为每年的6月中旬。1999和2000年的人工催产繁殖实践结果也显示大鲵在华南地区最佳繁殖期为6月中旬至7月中旬。 Since the introduction of Central China from southern China to southern China, and after its successful domestication, its law of gonadal development has also undergone special artificial ecological changes. Daphnia gonadal maturity coefficient of maximum, from the natural birthplace of the Otawan early in mid-August to mid-July to mid-July. According to the annual glandular maturity accumulated temperature in Okuma, the gonadal maturity of Okinawa is also mid-June each year. The results of artificial ovulation breeding in 1999 and 2000 also showed that the best breeding season of Dajiao in southern China was from mid-June to mid-July.
