Nearshore fisheries in the Main Hawaiian Islands encompass a diverse group of fishers using a wide array of gears and targeting many different species. Communities in Hawai’i often rely on these fisheries for economic, social, and cultural services. However, the stress from overfishing can cause ecosystem degradation and long-term economic loss. This layer represents the estimated average annual catch of reef fish by all gear types and fishers (kg/ha). It is the summed total of the other OTP fishing layers (Commercial Total, Non-Commercial Shore-based Total, and Non-Commercial Boat-based Total). Commercial catch data comes from Hawaii Division of Aquatic Resources. Non-commercial catch data was estimated from Marine Recreational Information Program (MRIP) combined fisher intercept and phone survey data, see McCoy (2015) and McCoy et al. (in prep) for more details.McCoy K. 2015. Estimating nearshore fisheries catch for the main Hawaiian Islands. Thesis. University of Hawai‘i at Manoa.McCoy, K., Friedlander, A., Kittinger, J., Ma, H., Teneva, L., Williams, I.D. In prep. Estimating nearshore fisheries catch for the main Hawaiian islands. PLoS One.This layer was developed as part of a geospatial database of key anthropogenic pressures to coastal waters of the Main Hawaiian Islands for the Ocean Tipping Points project (http://oceantippingpoints.org/). Ocean tipping points occur when shifts in human use or environmental conditions result in large, and sometimes abrupt, impacts to marine ecosystems. The ability to predict and understand ocean tipping points can enhance ecosystem management, including critical coral reef management and policies to protect ecosystem services produced by coral reefs. The goal of the Ocean Tipping Points Hawaii case study was to gather, process and map spatial information on environmental and human-based drivers of coral reef ecosystem conditions.
