目前人工繁殖所用的亲鲶基本上来源于天然水域，由于生态环境的恶化和捕捞强度的加剧，从天然水域中捕获的鲶数量锐减，采集亲鲶极为困难，使苗种供应远远满足不了生产需要，制约着养线的发展。为了解决亲鲶来源不足，同时也为发展鲶养殖开辟一条苗种供应的新途径，我们利用人
At present, the artificial catfish used in artificial breeding is basically derived from natural waters. Due to the worsening of ecological environment and the intensification of fishing intensity, the number of catches captured from natural waters has dropped sharply. It is extremely difficult to collect the catfish so that seed supply can not meet the supply The need of production restricts the development of supporting lines. In order to solve the problem of insufficient source of the catfish and to open up a new supply of seed for the development of catfish farming,
