香港后海湾池塘养殖业发展简况与可持续发展

自20世纪40年代,后海湾就成为香港的池塘养殖中心。虽然在过去数十年间池塘养殖业的管理效率及水产品质量得到了不断提高及改良,但仍然未达到现代化的生产水平。1990年代中期,由于多种因素的共同作用,养殖业逐渐衰落。与此同时,香港政府指定后海湾一带的商业鱼塘为"资源合理利用区",肯定了鱼塘对湿地物种养护及养殖户经济收益的重要性。有见及此,世界自然基金会香港分会通过共同管理模式与养殖户合作,借助"绿色养殖",在社会、经济、生态三方面实现高度协调,尝试把后海湾逐渐衰落的池塘养殖业发展成为可持续发展工业。

The development of pond-culture industry around the Hong Kong Deep Bay and its sustainable development

Since the 1940s,the Deep Bay has been a pond-culture center in Hong Kong.Although continuous improvements in management effectiveness and product quality of the pond-culture industry has been witnessed in the past decades,the industry has yet to reach modernized productivity levels.In the mid-1990s,the industry saw a decline due to a combination of various factors,While the same time,the Hong Kong Government then designated certain commercial fishponds around the Deep Bay as a " wise use" area to recognize the importance of fishponds to wildlife biodiversity and fish farmers' livelihood.In response to such opportunities,WWF Hong Kong started collaborating with fish farmers to co-manage the fishponds.Through management agreements,WWF Hong Kong hopes that the " Eco-fish" pond-culture management concept can help strike a balance between conservation and the social and economic needs of the society so as to encourage fishponds to be managed in a sustainable manner.
