摘要
在我国,鱼类养殖是一项重要的商业活动。鱼类养殖在过去几十年的快速发展过程中,对水环境产生了重要影响。研究表明:鱼类养殖对养殖区鱼、浮游生物、水生植物群落结构和水质变化有重要影响。现在,几乎所有的鱼类养殖系统都在一定程度上受到了损害。随着人们环境保护意识的增强,鱼类养殖的环境效应和渔业管理问题已引起了社会的广泛关注,渔业管理不再仅仅是通过开发资源以获取最高产量。 面临挑战,人们应该采取切实可行的步骤,从传统的渔业管理转变到基于生态系统的渔业管理,将渔业纳入生态系统管理以保障养殖业的可持续发展。
Fish culture is an important commercial practice in China. The rapid development of fish culture industry over last few decades has aroused the increasing concern about its impact on the marine and freshwater environments involved. Recent studies show that great changes in community structure of fish, plankton and aquatic macrophytes, as well as in water quality could take place in fish culture zones, and most fish culture systems have been threatened in some degree. Environmental effects and fisheries management of the fish culture zones have become the focus of growing concern. Fisheries management is no longer a question of maximizing the yield of commercially exploited resources. In order to achieve the sustainable aquaculture, practical steps should be defined to move from the traditional fisheries management framework to ecosystem-based management.
