摘要

There is about 5600 000 hm2 of rice field in Northeast China,in which only 2％ is conducted in paddyfield aquaculture,showing a broad prospect for paddyfield culture.The crab-rice and fish-rice are the main model of paddyfield aquaculture.In past years,there was 80 000 hm2 of rice field with paddyfield aquaculture in Liaoning province,and the new paddyfield aquaculture technology and patterns are introduced to Heilongjiang and Jilin Provinces to explore the optimum paddyfield aquaculture models based on local resources.Currently,the paddyfield aquaculture in Northeast China is facing with the stage of rapid development toward a trend of specialization,large-scale,industrialization,excellent quality,and brand marketing.%东北地区水稻种植面积达5 600 000 hm2,但稻田养殖面积利用率仅为2％,主要为稻田养鱼和稻田养蟹,具有广阔的开发前景.近年来,辽宁省的稻田养殖80 000hm2,发展较快.黑龙江和吉林地区结合当地的环境条件,引进了稻田养殖新模式、新技术,发展具有特色的稻田养殖模式.当前,东北地区稻田养殖仍处于快速发展阶段,需进一步向专业化、规模化、产业化、优质化、品牌化发展.
