Hawaiʻi Shallow-Set Longline Fishery Quarterly and Annual Status Report 2020

April 16, 2021

Pacific Islands Region Observer Program Hawaiʻi shallow-set longline data reports of observer coverage, protected species interactions, and set and hook unit effort for vessels arriving with observers during 2020.

NOAA Fisheries monitors the Hawaiʻi shallow-set pelagic longline fishery (targeting tunas) through a mandatory observer program. This report summarizes data for deep-set fishing trips. It ensures prompt dissemination of Hawaiʻi longline observer data, and may be revised after final data editing. The following table summarizes the percent observer coverage for vessel departures, vessels arriving with observers, protected species interactions, and set and hook unit effort for vessels arriving with observers.

Seabirds per 1,000 hooks0.0980.0040.054
Marine mammals per 1,000 hooks0.0000.0370.017

The percent coverage is based on vessel departures. Protected species interactions are based on vessel arrivals. For the purpose of this report, an animal that is hooked or entangled is considered an interaction.
