1现状 1.1消费状况 1.1.1渔业产量 近年来养殖业发展很快，近两年全国水产品产量统计资料（见表 1）。其中海产品养殖产量增加最迅速，淡水渔业养殖也已发展到相当规模。从理论上讲，淡水渔业养殖的料肉比较陆生动物低，淡水渔业养殖的回报率相对较高。而淡水渔业养殖在刚发展? 1 Status quo 1.1 Consumption 1.1.1 Fisheries production Aquaculture developed rapidly in recent years, the past two years the national aquatic product output statistics (see Table 1). Among them, aquaculture production has been increased most rapidly and freshwater fishery farming has also grown to a considerable size. In theory, freshwater fisheries feed more low-terrestrial animals, freshwater fisheries breeding relatively high rate of return. Freshwater aquaculture breeding just developed?
