摘 要: | 用1000m3水体的室内育苗池和6口海水土池塘(计19hm2)培育中华绒螯蟹(Eriocheirsinensis)苗,比较两种河蟹人工繁殖技术的生态效益和经济效益。经35天培育表明,土池培育1kg大眼幼体可获利2063元,比室内育苗获利(393元)高42倍;产出投入比(207)比室内育苗(133)高4577%。若采用土池育河蟹苗,每年至少可以少排放各种化学药物420t。

Abstract: | Evaluation of profits from artifical reproduction of Chinese mitten crab (Eriocheir sinensis)was carried out both in earthern seawater ponds and in indoor tanks in 1998.There were an average yield of 1875kg/hm2(maximum 42kg/hm2)and profits of 2063 yuan RMB/kg megalopa in earthern Ponds,as much as 42 times higher than that in indoor tanks.The waste seawater with various chemicals used in the artifical reproduction of Chinese mitten crab in indoor tanks was reduced by 4200000 tons.The output-input ratio was 4577% higher in earthern seawater ponds than in an indoor tank. |
