目前池塘主养青虾,若能将平均单位面积产量提高到80公斤/0.067公顷,则可取得较好的经济效益。现将提高池塘主养青虾单位面积产量的关键技术介绍如下: (一)池塘条件 (1)水源。水源充足,水质清洁无污染,符合渔业用水标准,进排水方便。(2)虾塘。面积不宜过大,以0.201~3.35公顷为好。(3)虾塘坡度和水深。坡度1:2.5~1:3,水深1.2~1.5米。(4)底质。淤泥不超过10厘米,底部向排水处有一定的倾斜。
Currently the main pond freshwater prawn, if the average yield per unit area increased to 80 kg / 0.067 hectares, you can get better economic benefits. Nowadays, the key technologies for improving the yield per unit area of the main freshwater shrimp in ponds are introduced as follows: (I) Conditions of ponds (1) Water sources. Adequate water, clean water, pollution-free, in line with the standards of fishery water, easy access to drainage. (2) shrimp ponds. The area should not be too large, with 0.201 ~ 3.35 hectares as well. (3) shrimp pond slope and water depth. Slope 1: 2.5 ~ 1: 3, depth of 1.2 to 1.5 meters. (4) substrate. Silt no more than 10 cm, the bottom of the drainage there is a certain tilt.
