Currently, information on nearshore reef-associated fisheries is frequently disparate or incomplete, creating a challenge for effective management. This study utilized an existing non-commercial fishery dataset from Hawai'i, covering the period 2004-13, to estimate a variety of fundamental fishery parameters, including participation, effort, gear use, and catch per unit effort. We then used those data to reconstruct total catches per island. Non-commercial fisheries in this case comprise recreational, subsistence, and cultural harvest, which may be exchanged, but are not sold. By combining those data with reported commercial catch data, we estimated annual catch of nearshore reef-associated fisheries in the main Hawaiian Islands over the study period to be 1,167,758 ± 43,059 kg year-1 (mean ± standard error). Average annual commercial reef fish catch over the same time period-184,911 kg year-1-was 16% of the total catch, but that proportion varied greatly among islands, ranging from 23% on O'ahu to 5% on Moloka'i. These results emphasize the importance of reef fishing in Hawai'i for reasons beyond commerce, such as food security and cultural practice, and highlight the large differences in fishing practices across the Hawaiian Islands.
目前，近岸珊瑚礁渔业的信息经常存在差异或不完整，这给有效管理带来了挑战。本研究利用了夏威夷现有的非商业渔业数据集，涵盖了 2004-13 年期间，以估计各种基本渔业参数，包括参与度、努力程度、渔具使用和单位努力的渔获量。然后，我们使用这些数据来重建每个岛屿的总渔获量。在这种情况下，非商业渔业包括娱乐性、生计性和文化性捕捞，这些捕捞可能会被交换，但不会被出售。通过将这些数据与报告的商业捕捞数据结合起来，我们估计在研究期间夏威夷群岛近岸珊瑚礁渔业的年捕捞量为 1167758 ± 43059 公斤/年（平均值 ± 标准误差）。同一时期的商业珊瑚鱼年平均捕捞量为 184911 公斤/年，占总捕捞量的 16%，但在各岛屿之间差异很大，瓦胡岛为 23%，莫洛凯岛为 5%。这些结果强调了珊瑚礁捕鱼在夏威夷的重要性，原因不仅在于商业，还在于粮食安全和文化实践，同时也突出了夏威夷群岛之间捕鱼实践的巨大差异。
