| 摘 要： | 按青虾摄食、栖息生态习性设计池塘青虾养殖工艺，养殖实践表明：（１）采用虾苗一次放养，每１０００ｍ＾２池塘面积投放４．５－７．５万尾虾苗，饲养期间采用地分期分批捕捞的方法，青虾养殖池塘每１０００ｍ＾２净产为９０－１５０ｋｇ，其中６０－７０％的商品虾规格可达２．０－２．５ｇ以上。（２）采用一年二茬养殖青虾的方式，每１０００ｍ＾２净产可达２０４．３ｋｇ左右，但操作较为复杂。（３）青虾高产养殖池塘以面积６

| Abstract: | According to feeding and habitat ecology the technical process of Macrobrachium nipponense culture was designed. By the cultivating practice the following resultswere recorded: (1) The production of M. nipponense was 90 - 105kg/1000m2, the prawns(2.0- 2. 5g/ind) had 60-70%, when one time breeding prawn fry, much times catchingprawns per year. (2) The yield of M. nipponense was 204kg/1000m2, when two tirnes breeding fry, two times catching prawns, but it was too miscellaneous. (3) It is nice that the fishpond was rectangle, 667- 2000m2 culture area, 1.0m depth of water per pond. (4) It is goodthat the protein in diets of M. nipponense was 35-40%, two times exchange water per day,the ratio of feeding was 2. 8-8.0%. |
