Abstract:
Overall, this synthesis is the first ever, comprehensive examination of reef fish assemblage structure across Hawaii. The results show clear, distinct bioregions across the archipelago that give us a better understanding of reef fish macroecology and have important implications for management at the regional scale. The findings from this study also highlight the negative impacts of human population pressure on reef fishes, particularly around Oahu and Maui. When compared with the NWHI, a large proportion (42%) of MHI reef fish stocks were below 25% of unfished abundance. However, there are still remote areas in the MHI that that provide refugia and help sustain fish stocks, therefore these areas are important conservation hotspots. MMAs were shown to be effective in conserving fishes, especially around Oahu and Maui where fishing pressure is extremely high outside of MMS. However, most of these areas are too small to have substantial fisheries benefits. As a result, a more holistic approach that includes community-based management, expansion of the MMA network with a greater emphasis on no-take reserves, improvements to current fisheries regulations including enhanced enforcement efforts, and finally a greater emphasis on marine education awareness are necessary"--Executive summary (Page 4).
