根据鳖的自然生活习性,人工营造良好的水体生态环境、适当降低鳖的种群密度、提供足量的鳖喜食饵料,是养殖优质仿野生鳖的重要技术措施。试验显示:每1 hm2放养大规格鳖种(200 g/只)1500~2 250只,实行鳖鱼虾生态混养,符合健康养殖的要求,其管理难度较小,投入产出比可达1∶1.85以上,具有较好的推广前景。
According to the natural living habits of the turtles, it is an important technical measure to breed the high quality imitation wild turtle by artificially creating a good water ecological environment, appropriately reducing the population density of the turtles and providing enough turtle feed. The experiment showed that the large turtle species (200 g / bird) was stocked every 1 hm2 from 1,500 to 2,250, and the ecological polyculture of the soft-shelled turtle shrimp was carried out in line with the requirements of healthy breeding. The management is difficult and the input-output ratio can reach 1 : 1.85 or more, with good promotion prospects.
