看到标题大家可能会想,海洋中不能种植粮食啊,怎么能成为未来的粮仓呢?是的,海洋里不能种水稻和小麦,但是,海洋中的鱼类和贝类却能够为人类提供味道鲜美、营养丰富的蛋白食物。大家知道,蛋白质是构成生物体的最重要的物质,是生命的基础。现在人类消耗的蛋白质中,由海洋提供的不过5%～10%。令人焦虑的是,20世纪70年代以来,海洋捕鱼产量一直徘徊不前,不少品种已经呈现枯竭现象。要使海洋成为名副其实的粮仓,鱼鲜产量至少要比现在增加10倍才行。美国某海洋饲养场的实验表明,大幅度地提高鱼产量是完全可能的。
If you look at the headline, you may wonder why the grain can not be planted in the ocean. How can it be the granary in the future? Yes, rice and wheat can not be planted in the sea. However, fish and shellfish in the oceans can provide human taste Delicious, nutritious protein food. Everyone knows that protein is the most important substance that constitutes an organism and is the basis of life. Now human consumption of protein, provided by the ocean but less than 5% to 10%. What worries people is that since the 1970s, the output of marine fishery has been stagnant, and many species have been depleted. To make the ocean a veritable granary, the output of fish should be at least 10 times more than it is now. Experiments in a U.S. marine farm have shown that it is entirely possible to significantly increase fish production.
