据世界粮农组织水产养殖部负责人Colin Nash说,到本世纪末世界水产养殖产量将达到2200万吨。这一目标是可以达到的,只是贝类和藻类仍占有相当重要的地位。其原因是食品工业需要大量的海藻制品,贝类养殖投资较小。 Nash说,今后养殖产量的增长主要是鱼,尤其是在温带水域,包括在近海、湖泊、水库中进行粗放养殖是增加产量的主要途径。半精养、精养的产量不会占据主导地 According to Colin Nash, head of the World Aquaculture Department at the World Food Program, the world aquaculture production will reach 22 million tons by the end of this century. This goal can be achieved, but shellfish and algae still occupy a very important position. The reason is that the food industry requires a large amount of seaweed products and the investment in shellfish farming is relatively small. Nash said that the future growth of farmed fish production is mainly of fish, especially in temperate waters, including extensive farming in offshore, lakes and reservoirs, as the main way to increase production. Semi-intensive, intensive production will not dominate
