FishData

Compile and harmonize catch rates from fishery-independent surveys of fish populations

Description

• Scrape and harmonize bottom trawl survey data from Alaska Fisheries Science Center and Northwest Fisheries Science Center
• Adds zeros (sampling occasions without catch of any given species) automatically
• Stores data locally to avoid excessive survey usage
• Hopefully with be moved to an rOpenSci project to ensure that code is applicable for multiple surveys, regions, and agencies
