Nearshore fisheries in the main Hawaiian Islands (MHI) have great economic, recreational, and cultural value. Currently, information on these fisheries is disparate and incomplete, creating a challenge for effective management. This study combines and synthesizes several commercial and small-scale non-commercial datasets to estimate the total catch of nearshore fisheries in the MHI. Data used came from catch reports submitted by commercial fishers, a statewide recreational fisheries survey, and 12 small-scale, non-commercial creel surveys conducted at sites in Kauai, Oahu, Lanai, Maui, and Hawaii. Results include an estimated range for total nearshore catch of between 1,441,407 and 6,731,832 kg/yr, with non-commercial catch being between 9 and 46 times reported commercial reef fish catch. Additionally this study provides a comprehensive overview of the MHI nearshore fishery, including best-available estimates of fishery data such as CPUE, gear-preference and participation rates, with data broken out at island-scale, which likely is more appropriate for management purposes than the statewide level at which nearshore catch data is currently reported in the MHI.
