Commercial Line Fishing (Estimated Average Annual Catch of Reef Fish), 2003-2013

Description:

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 average annual commercial catch of reef fish by line fishing over the years 2003 - 2013 as reported in commercial catch data collected by the State of Hawai’i, Department of Aquatic Resources (DAR) Commercial Marine Landings Database (CML). “Line fishing” is a fairly broad category that can include casting, trolling, hand line, short line and others. These gears were grouped together for consistency with non-commercial catch estimates from McCoy (2015). Commercial catch is reported to DAR in large irregular reporting blocks, by gear and by species.McCoy K. 2015. Estimating nearshore fisheries catch for the main Hawaiian Islands. Thesis. University of Hawai‘i at Manoa. 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. Please contact the Ocean Tipping Points project in advance of applying these data sets to project work so the PI can track and communicate data uses and ensure no duplicate efforts are underway. When applying these data for publication, please reference and cite the complete journal article, Wedding et al. 2017. This layer is presented in the WGS84 coordinate system for web display purposes. Downloadable data are provided in native coordinate system or projection.
