摘　　要：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。52 net-cages with the area 25square meters were put in the water of collapsed area to carry out the experiment.300 fingerlings of which the body length of bighead carp was 165gram on average were stocked in every net-cage.Microecologics and artificial food inducing techniques were applied to ensure the food supply.After 137days of rearing,the unit yield reached 19.72 kilogram per square meter,of which the unit yield of bighead carp was 14.97 kilogram,the productive value of the net-cage culture was 138.06 yuan per square meter, the profit was 99.66yuan per square meter and the rate of input and output was 1:3.59.
