Hawaii Deep-Set Longline Fishery Quarterly and Annual Status Report 2022

August 19, 2022

Pacific Islands Region Observer Program Hawaii deep-set longline data reports of observer coverage, sea turtle, marine mammal, sea bird, ESA-listed elasmobranch interactions, and set and hook unit effort for vessels departing with observers during 2022.

NOAA Fisheries monitors the Hawaii deep-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 Hawaii longline observer data, and may be revised after final data editing. The following table summarizes the percent observer coverage for vessel departures, vessels departing with observers, and set and hook unit effort for observed vessels based on departure date. The tables also summarize sea turtle, marine mammal, sea bird, and Endangered Species Act-listed elasmobranch interactions based on the begin haul date. Unidentified elasmobranch species that could be an ESA-listed species are also included.
