要提高鱼的产量，应进行鱼塘冬季改造。一、浅改深。可结合冬修水利挖塘清淤（底淤应留30厘米厚），加高培厚塘埂。淤泥多者，还可以作为塘边种植鱼用青饲料的基肥。挖后，使淤积的浅塘水深增至2．5米以上，既可增强蓄水抗旱能力，又可高产混养减少鱼病，防止鱼浮头泛塘。二、 To improve fish production, fish ponds should be rebuilt in winter. First, shallow change deep. Can be combined with Dongxiu water conservancy digging pond dredging (silt should stay 30 cm thick), increase training thick pond 埂. More silt, but also can be used as ponds to cultivate fish with basal feed. Digging, the siltation of the shallow pond water depth increased to 2.5 meters or more, can enhance the capacity of water storage drought, but also high-yield polyculture to reduce fish diseases, prevent fish floating Pan Tong. two,
