在未治理塌陷地水域,设置生态养鳙网箱52箱。使用生态养殖技术(不投饵),利用微生物制剂及人工诱导饵料生物技术,在25m~2网箱内放养鱼种300尾,其中鳙规格为165g／尾。经过137天的养殖,网箱平均单产19．72kg／m~2,其中鳙单产14．97kg／m~2,折合每667m~2产鳙9985kg。网箱平均产值达138．06元／m~2,净收入为99．66元／m~2,投入产出比为 1∶3．59。 In the uncontacted subsidence area, 52 ecological cages were set up. The use of ecological farming techniques (not feeding), the use of microbial agents and artificial bait biotechnology induced stocking 300 fish-tail in 25m ~ 2 cages, of which 鳙 size of 165g / tail. After 137 days of breeding, the average yield of cages was 19.72kg / m ~ 2, in which the yield was 14.97kg / m ~ 2, equivalent to 9985kg per 667m ~ 2 production. Cage average output value of 138.06 yuan / m ~ 2, net income of 99.66 yuan / m ~ 2, input-output ratio of 1: 3.59.
