The Global Fishing Watch dataset provides data on fishing effort, measured in hours of inferred fishing activity, from 2012 to 2017.
-
The dataset includes information on various fishing gear types, including drifting longlines, fixed gear, purse seines, squid jiggers, trawlers, and other fishing methods.
-
Each data asset represents the fishing effort for a specific flag state and day, with bands indicating the activity level for each gear type.
-
The data is available at a resolution of 1113.2 meters and is licensed under a Creative Commons Attribution-ShareAlike 4.0 International license (CC-BY-SA).
