摘要
我国现阶段水产养殖业的发展同时面临着增产、减排、节能任务,其艰巨性在古今中外绝无仅有。就目前的发展方式而言,集约化发展可以解决增产问题,全封闭循环水养殖可以解决排污问题,但随着集约化程度的提高,生产单位产品的耗能或CO2排放量也会急剧增加。在我国人口继续增加和全球气候急剧变化的大背景下,我们即需要应对食物安全也不能忽视环境保护,即要认真对待短期急需又要考虑长远发展,时代在呼唤水产养殖业发展模式的创新。
Aquaculture development in China is facing three missions simultaneously, viz. production improving, sewage reducing and energy saving. In terms of the current mode of deyelopment, intensification of aquaculture systems can improve production, water recirculating system can solve the problem of sewage discharge, however, with the intensification of aquaculture systems energy consumption per weight gain will rise dramatically. Due to population growth in China and global climate change our era calls an innovation in aquaculture development mode. Eco-Intensification of Aquaculture is the efficient production of safe fish supplies in a way that protects environment, reliefs the pressure of aquaculture on wild fisheries, promotes social and economic development. Industrilized solar aquaculture systems, Integrated aquaculture, Inner partitioned polyeulture in ponds and Offshore mariculture are recommended in the paper as examples of ecological intensification in aquaculture.
