前言我省松嫩平原泡沼、水库星罗棋布面积约有50万亩左右,由于这些水面含碱量较高,浊度较大,致使水生动、植物和鱼类的种群和数量均较少。据1986年的统计资料,这部分水面平均亩产鱼仅在2.5—4公斤,鲫鱼占90％。水面的经济效益和社会效益很低。为了探索大、中盐碱水面的高产量,高效益的技术措施,为开展大中型水面精养摸出一条路子,使这些闲置多年的水面得到充分 Preface Our province Songnen Plain bubble marshes, reservoirs dotted about an area of ​​about 500000 acres, due to these high water content of alkali, turbidity larger, resulting in aquatic animals, plants and fish populations and quantities are less. According to 1986 statistics, this part of the average surface water per mu of fish is only 2.5-4 kg, carp accounted for 90%. The economic and social benefits of water are low. In order to explore the large, medium-saline high-yield, high efficiency technical measures to develop large and medium-sized water refinement to find a way to make these idle for many years to get the full surface
