近年来,人们对淡水虾的需求持续上升。淡水虾的养殖前景依然喜人。青虾养殖应把主攻方向放在提高亩产上。青虾养殖方式简单,成本较低,苗种繁殖容易,但产量不稳定,亩产量一般在100公斤左右,高的可达200公斤以上,低的只有几十公斤,成虾个体间差异还较大,由于螃蟹价格下跌,有一些养蟹户可能转养青虾,故青虾价格有下跌的可能。所以,养殖青虾要采取双季养殖、科学管理、轮捕上市的方法,提高亩产量提高效益。才能避免风险获得丰厚的回报。罗氏沼虾适合大众消费,搞好虾病防治是养殖的关键。罗氏沼虾的亩产量,一般在150公斤左右,高的可达200—300公斤,且市场价格较低,每公斤只有25元左右,因而很受普通 In recent years, the demand for freshwater prawn has been on the rise. Freshwater prawn breeding prospects are still gratifying. Freshwater shrimp farming should focus on improving mu yield. Freshwater shrimp farming method is simple, low cost, seed breeding easy, but the output is unstable, the yield per mu is generally about 100 kg, up to 200 kg high, low only tens of kilograms, shrimp individual differences are also more Large, due to the decline in crab prices, some crabs may transfer green shrimp, so the price of shrimp may have fallen. Therefore, aquaculture aquaculture to take double season farming, scientific management, round the catch market methods, improve the yield per acre to improve efficiency. In order to avoid the risk of getting huge returns. Macrobrachium for public consumption, do shrimp prevention and control is the key to farming. Macrobrachium rosenbergii production per mu, generally about 150 kilograms, up to 200-300 kilos high, and the market price is low, only 25 yuan per kilogram, so very ordinary
