Research on ecological and efficient mixed culture technology of Chinese mitten crab and Macrobrachium rosenbergii in Chongming
To fully tap into the potential of Chinese mitten crab(Eriocheir sinensis)ponds and utilize the space in water bodies,thereby increasing economic benefits per unit area,a mixed cultivation ex-periment was conducted in Chongming,Shanghai,involving different densities of giant freshwater prawn(Macrobrachium rosenbergii)alongside the traditional E.sinensis farming model.The results indicated that,under the condition of stocking 250 kg/hm2 of E.sinensis,the optimal stocking densi-ty for M.rosenbergii was 18 000 ind./hm2.With a selling price of 200 yuan/kg for M.rosenbergii,the total output value was 59 850 yuan/hm2 higher compared to stocking 24 000 ind./hm2.This re-presented an additional 61 950 yuan/hm2 compared to monoculture of E.sinensis.
