针对当前浙江沿海水产养殖密度过大带来环境污染的新趋势，国家海洋局宁修仁研究员日前提出：采用混合饲料喂养是渔民增收和保护环境的双赢之路。近年来，浙江省水产养殖业较高的经济效益，驱使养殖户投放网箱的数量和密度急剧增加，养殖户普遍用小杂鱼制成的鱼浆进行喂养，其 In light of the new trend of environmental pollution caused by the over-large-scale aquaculture in Zhejiang coast, Researcher Ning Xuren of State Oceanic Administration recently proposed that adopting mixed-feed feeding is a win-win way for fishermen to increase income and protect the environment. In recent years, the relatively high economic benefits of aquaculture in Zhejiang Province have driven the number and density of cages populated by farmers to increase rapidly. Farmers generally feed their fishmeal with small trash fish.
