由于葛洲坝工程的修建阻隔了中华鲟洄游到上游产卵场的通道,对中华鲟的救护被推向前台。从自江中捕捞中华鲟野生亲鱼转至建立中华鲟的人工养殖群体,中华鲟保护已历经三十个春秋。三十年来,从对葛洲坝坝下中华鲟性腺发育的调查到使用人工激素LRHA替代鲟鱼脑垂体,从剖腹取卵到活体无创伤采卵,从成功培育出子一代中华鲟亲鱼到全人工繁殖子二代中华鲟的诞生,中华鲟保护走出了一条非凡之路。
Due to the construction of the Gezhouba dam blocking the migration of Chinese sturgeon to the upstream spawning ground, the rescue of Chinese sturgeon is pushed to the foreground. From the river fishing Chinese sturgeon wild broodstock transferred to the establishment of artificial breeding groups of Chinese sturgeons, sturgeon protection has gone through thirty years. In the past 30 years, from the investigation of the gonadal development of Chinese sturgeon under the dam of Gezhouba Dam, the artificial hormone LRHA was used to replace the pituitary gland of sturgeon, and ovulation from the cesarean section to the non-invasive ovum in vivo. From the successful breeding of the first generation Chinese sturgeon broodstock to the whole artificial propagation The birth of the second generation Chinese sturgeon, Chinese sturgeon protection out of an extraordinary way.
