近几年,北京地区鲟鱼养殖业发展迅速,市场销路好,发展前景广阔,但是鲟鱼养殖苗种主要依赖国外进口和捕捞天然水域的野生亲鱼进行繁殖获得。国外进口的苗种不但价格昂贵,而且受到国外相关法规限制,数量无法保障;野生捕捞的亲鱼也将随着天然资源的不断衰竭,而出现数量急剧减少的困境,而且多数品种已处于濒危或极危状态。可以预见,鲟鱼苗种将成为制约未来国内鲟鱼产业发展的瓶颈,因此,立足自身研究以解决鲟鱼人工繁殖技术,生产优质鲟鱼苗种已成为目前国内急需解决的问题。 In recent years, the sturgeon aquaculture industry in Beijing has been developing rapidly, its market is well sold and its development prospect is promising. However, the sturgeon breeding seed mainly relies on the wild broodstock imported and caught in natural waters for breeding. The imported seeds are not only expensive, but also restricted by the relevant laws and regulations in foreign countries. The number of wild-caught broodstock will also decline drastically with the depletion of natural resources. Most species are already at risk or extremely vulnerable Dangerous state. It is foreseeable that the sturgeon seed will become the bottleneck restricting the development of sturgeon industry in the future. Therefore, based on its own research to solve the artificial breeding of sturgeon, the production of high-quality sturgeon seed has become an urgent problem to be solved urgently in China.
