草鱼种与泥鳅池塘双主养模式养殖试验

Preliminary Experiment on Double Main Culture Model of Grass Carp Fingerling and Loach in High-yield Ponds

[目的]降低草鱼池塘养殖生产成本,提高池塘水体利用率和综合养殖效益,增强养殖模式的抗风险能力以及示范推广作用。[方法]在江苏省宿迁市宿城区中扬镇开展了草苗种、泥鳅池塘双主养模式养殖试验。[结果]放养260尾/kg的泥鳅苗种180 000尾/hm^2,放养2 000尾/kg的草苗种60 000尾/hm^2的养殖模式,以及放养260尾/kg的泥鳅苗种120 000尾/hm^2,放养2 000尾/kg的草苗种75 000尾/hm^2的养殖模式,产出投入比均较高。[结论]放养260尾/kg的泥鳅苗种120 000尾/hm^2,放养2 000尾/kg的草苗种75 000尾/hm^2的养殖模式更容易被养殖者接受,更容易被大面积推广应用。

[ Objective ] The research aimed to improve the utilization rate of water system in grass carp fingerling pond, the composite culture benefit, the anti - risk ability, the achievements of demonstration and extension. [ Method ] Efficient culture experiment was made in the breeding base in Zhongyang Town, Sucheng District of Suqian City in Jiangsu Province. [ Result] The output-input ratio of the experiment re- sult of 2# pond （ stocking 180 000 ind./hm2 loach with the size of 260 ind./kg and 60 000 ind./hm2 grass carp fingerling with the size of 2 000 ind./kg） and 3# pond（ stocking 120 000 ind./hm2 loach with the size of 260 ind./kg and 75 000 ind./hm2 grass carp fingerling with the size of 2 000 ind./kg） showed higher economic efficiency. [ Conclusion] The recommended efficient double main culture model of grass carp fin- gcrling and loach was stocking 120 000 ind./hm2 loach with the size of 260 ind./kg and 75 000 ind./hm2 grass carp fingerling with the size of 2 000 ind./kg.
