当水温稳定在25℃左右时,罗氏沼虾苗三个月即能长成上市规格,我国大部分地区具备三个月以上高温25～30℃,可进行罗氏沼虾的养殖。罗氏沼虾能广泛地摄食多种天然、人工动植物饵料。在生产季节,罗氏沼虾的养殖与一龄鱼种培育基本同步。实践证明,在主养一龄草鱼种池内混养罗氏沼虾,不但可充分利用水体空间和饵料,提高饵料报酬,而且能增加单位面积鱼种池的产值和效益。 When the water temperature is stable at about 25 ℃, Macrobrachium rosenbergii can grow into a market specification in three months. Most parts of China have a temperature of 25-30 ° C for more than three months and can be used for the culture of Macrobrachium rosenbergii. Macrobrachium can eat a wide range of natural, artificial plant and animal feed. In the production season, the cultivation of Macrobrachium rosenbergii is basically synchronized with the cultivation of primary fish species. Practice has proved that in the primary culture of grass carp species Macrobrachium rosenbergii, not only can make full use of water space and food, improve feed remuneration, but also increase the unit area of ​​fish production and efficiency.
