稻田养殖罗非鱼能实现“一水两用、一田双收、粮渔双赢”。实践表明:利用稻田养殖罗非鱼,可部分利用罗非鱼的杂食性优势,清除稻田中的害虫和杂草,节省人力和物力。同时,因罗非鱼经常在田块中活动,能够起到疏松土壤的作用,罗非鱼排出的粪便又能为水稻生长提供天然的有机肥料,能使稻谷增产5%~15%,每亩(1亩=667平方米,下同)还可产出罗非鱼30~50千克,其他成鱼50~75千克,每亩可新增产值
Rice farming tilapia can achieve “a water dual use, a field double income, food and fisheries win-win ”. Practice shows that: the use of tilapia farming rice fields, tilapia can be part of the advantages of omnivorous, clear pests and weeds in paddy, save manpower and material resources. At the same time, tilapia often acts on plots, which can play the role of loose soil. The excrement of tilapia can provide natural organic fertilizer for rice growth, which can increase rice yield by 5% -15% per mu (1 mu = 667 m2, the same below) can also produce tilapia 30 to 50 kilograms, other adults 50 to 75 kilograms, new output per acre
