夏威夷基亚韦岛哈埃纳地区的社区管理渔业保护区(CBSFA)通过严格的资源管理和传统捕鱼方法,实现了明显的生态恢复。该保护区于2015年获得指定,覆盖从海岸线到离岸1英里的水域 1。
根据第一个五年评估(2016-2020年),保护区内的鱼类数量、物种和生物量均超过保护区外的水平 1。社区成员观察到更多大型鱼群和多种鱼类物种的回归 1。
为确保资源的可持续管理,CBSFA实施了一系列规则,包括禁止使用鱼枪、禁止出售鱼类或海洋生物、禁止夜间潜水以及遵守特定物种的捕获限制 1。2018年4月的一场风暴对鱼类和海胆数量造成了负面影响,并引发了更多的珊瑚漂白 1。
第二次评估涵盖2016-2026年的数据,预计在秋季晚期发布 1。生态学家海瑟·伊利塔洛-沃德指出,海洋保护区需至少10年、更可能需30年才能检测到趋势 1。
这一模式的成功激发了夏威夷州约十多个其他捕鱼社区考虑推行类似的社区管理制度 1。同时,新法律规定董事会与社区组织可签订长达65年的共同管理协议 1。
The Haeʻena area on Kauaʻi island in Hawaii has demonstrated significant ecological recovery through a community-based subsistence fishery area (CBSFA) that prioritizes traditional fishing methods and strict resource management 1. Designated in 2015, the protected zone extends from the shoreline to one mile offshore 1.
Early research findings indicate that fish populations, species diversity, and biomass within the CBSFA exceed levels found outside the protected area, according to an initial five-year assessment covering 2016 to 2020 1. Community members have reported observing larger fish schools and the return of multiple fish species to the region 1. A second comprehensive evaluation spanning 2016 to 2026 is expected to be released in late autumn 1.
The CBSFA operates under strict regulations that prohibit spearfishing, the sale of fish or marine organisms, nighttime diving, and enforce catch limits on specific species 1. These rules reflect the community's commitment to sustainable resource management 1.
A 2018 April storm created setbacks by negatively affecting fish and sea urchin populations while triggering additional coral bleaching 1. However, ecologist Heather Ylitalo-Ward has noted that marine protected areas typically require at least ten years, and more likely thirty years, to establish detectable ecological trends 1.
New state legislation now permits the board and community organizations to establish joint management agreements lasting up to 65 years 1. The success of Haeʻena's model has inspired more than a dozen other fishing communities across Hawaii to consider implementing similar community management systems 1.
