1996年5—10月利用3口共11亩池塘进行罗氏沼虾单养高产试验。养殖前期侧重利用温室中间培育大规格虾苗,清塘肥水,及采取措施提高虾苗下塘成活率;养殖中期侧重强化饲料投喂,预防浮头,及调控好水质;养殖后期侧重采用综合的生态方法促进虾蜕皮生长,保证出塘虾质量,及商品虾捕捞均衡上市。经过4个月左右的养殖,平均亩产虾144.4kg,最高亩产226.5kg,平均亩净利润3458.6元。
From May to October 1996, a total of 11 acres of 3 ponds were used for single-yield and high-yield test of Macrobrachium rosenbergii. In the early stage of aquaculture, we focused on cultivating large-size shrimp seedlings and clear pond fertilizer in the middle of greenhouses, and taking measures to improve the survival rate of shrimp ponds under the ponds. In the mid-term, we focused on intensified feedstuffs feeding, floating head prevention and regulation of water quality. Methods to promote the growth of shrimp molt, to ensure the quality of pond shrimp, and commercial shrimp fishing a balanced market. After 4 months of farming, the average yield of shrimp 144.4kg, the highest yield 226.5kg, average net profit 3458.6 yuan.
