在未治理塌陷地水域,设置网箱生态养殖鳙鱼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25m2网箱内放养鱼种300尾,其中鳙鱼规格为165g/尾。经过137d的养殖,网箱平均单产19.72kg/m2,其中鳙鱼单产14.97kg/m2,折合667m2产鳙鱼9 985kg。网箱平均产值达138.06元/m2,净收入为99.66元/m2,投入产出比为1∶3.59。
In the uncontacted subsidence area, 52 cages were bred for ecological culture. The use of ecological farming techniques (no feeding), the use of microbial agents and artificial bait biotechnology induced stocking fish in 25m2 cage 300, of which the size of anchovy 165g / tail. After 137 days of breeding, the average yield of cages was 19.72kg / m2, in which the yield of mandarin fish was 14.97kg / m2, equivalent to 9858kg of 667m2 fish. Cages average output value of 138.06 yuan / m2, net income of 99.66 yuan / m2, input-output ratio of 1: 3.59.
