1.稻田养鱼的条件 (1)水质好,符合养鱼水质标准。 (2)水源好:需要水就有水灌田。 (3)能排洪、能保水:高产养鱼田应开有排洪沟,田埂应不垮塌和不渗漏。 (4)放养优良鱼种:放养耐水浅、耐高温、耐低氧、食性广的鱼类、草胡子鲶或罗非鱼和温水性鱼类如鲤鱼、鲫鱼、草鱼、白鲫及大口鲶、斑点叉尾鲴、云斑鮰、中华绒毛蟹等品种。草鱼必须在2—3月上旬注射出血病等免疫药物,在冬囤水田中,由于水位深,在稻谷收割后,可放养一些大规格的鲢鱼种养殖成鱼。 2.养鱼稻田基本建设 1. Conditions of rice culture (1) good water quality, in line with the fish water quality standards. (2) water is good: water needs water to irrigate fields. (3) to flood, to keep water: high-yielding fish farms should be opened flood discharge ditch, Tian 埂 should not collapse and no leakage. (4) stocking fine species: stocking shallow water, high temperature, hypoxia, diet wide fish, grass carp or catfish and tilapia and warm water fish such as carp, crucian carp, grass carp, white carp and catfish, Channel catfish, cloud maculopathy, Chinese hairy crabs and other varieties. Grass carp must be injected with an immunological drug such as hemorrhagic disease in early February to March. In the winter paddy field, due to the deep water level, some large-sized silver carp species can be stocked into adult fish after harvesting in paddy. 2. Fish farming infrastructure
