我们于1988～1989年进行了罗氏沼虾与一龄鱼种混养的试验,初步获得成功。1988年在2.6亩池塘中收获罗氏沼虾214.75公斤,平均亩产82.6公斤,虾出池规格平均17.8克,最大雄虾63.5克,最大雌虾40.2克,同时收获大规格一龄鱼种518.5公斤,平均亩产199.4公斤。1989年在5亩池塘中收获罗氏沼虾373.5公斤,平均亩产74.7公斤,虾出池规格平均17.5克,最大雄虾57.3克,最大雌虾39.7克,同时收获青虾57公斤,平均亩产11.4公斤,大规格一龄鱼种1222.5公斤,平均亩产244.5公斤。在鱼虾混养的技术方
We conducted a preliminary test of the polyculture between Macrobrachium rosenbergii and first instar species from 1988 to 1989. In 1988, the 2.6-hectare Macrobrachium was harvested in 2.6 mu of ponds, with an average yield of 82.6 kilograms per mu. The average size of shrimp in the pond was 17.8 grams, the largest male was 63.5 grams and the largest was 40.2 grams. At the same time, the large- , The average yield 199.4 kilograms. 1989 5 acres of ponds in the harvest of Macrobrachium rosenbergii 373.5 kilograms, average yield 74.7 kilograms, shrimp out of the pool specifications average 17.5 grams, the largest male 57.3 grams, the largest female 39.7 grams, while harvesting shrimp 57 kg, the average yield per mu 11.4 kilograms, 1222.5 kilograms of large size of one-year-old species, the average yield 244.5 kilograms.
