aquaculture is the fastest growing sector of animal-based food production for
human consumption. As the global population increases, pressure on coastal
ecosystems and the need to produce food also grow. More than half of the
world's population lives within 200 km (120 mi) of a coast, and many natural
fisheries are already fished at or over capacity.作者: miaoshi 时间: 2010-9-30 14:06
