河南省是大鲵的主要产地之一,上世纪70年代,由于人为大量捕捉和经济建设的加速发展,大鲵数量急剧减少,栖息地遭到严重破坏。为尽快恢复大鲵资源,河南省于90年代加大对大鲵的监管,鼓励人工驯养繁殖,积极开展大鲵人工增殖放流,大鲵养殖得到快速发展,目前全省大鲵存量约40万尾。但在新时期,河南省养殖大鲵产业面临一些困难和问题,为进一步加快养殖大鲵产业健康发展,促进农民增收增效,我们组织开展了大鲵的调查研究,现将有
Henan Province is one of the major producing areas of Taihu. In the 1970s, due to the massive capture of human beings and the accelerated economic development, the number of large clams was drastically reduced and the habitats severely damaged. In order to restore the resources of poplar trees as soon as possible, Henan Province increased its supervision of populus euphratica in the 1990s and encouraged artificial domestication and breeding.

However, in the new period, Henan aquaculture industry faces some difficulties and problems. In order to further accelerate the healthy development of aquaculture industry and promote farmers’ income and increase efficiency, we organized the investigation and study of the aquaculture industry. Now we have
