28 Atlantic Highly Migratory Species Pelagic Observer Program CPUE
Description: CPUE from pelagic observer program (POP) observed hauls, presented as number of fish per haul, is provided for the northeast (i.e., the Northeast Coastal and Mid-Atlantic Bight fishing areas) by year/species from 1992-2023.
Indicator category: Database pull with analysis
Found in: State of the Ecosystem - Gulf of Maine & Georges Bank (2021+), State of the Ecosystem - Mid-Atlantic (2021+), State of the Ecosystem - Indicator Catalog (2024+)

Public availability statement: Source data are NOT publicly available. Pelagic observer data is considered confidential data, and must be screened to ensure that data meet requirements for “rule of three” at the set and vessel level before they can be distributed.
28.1 Methods
28.1.1 Data sources
Data for this indicator are sourced from the NOAA Southeast Fisheries Science Center, Pelagic Observer Program. These data come from the NOAA Southeast Fisheries Science Center databases holding the Atlantic highly migratory species information from the pelagic observer program.
The Southeast Pelagic Observer Program monitors the pelagic longline fleet all along the Northeast U.S. Shelf. This covers approximately 1000 hauls per year and targets 8% coverage of the fishing effort.
28.1.2 Data analysis
Catch per unit effort was calculated as number of individuals per haul and summarized by year and species.
The species groupings are available in the table below.

28.1.3 Data Processing
HMS staff sent a request for data to POP Observer Program staff (Sascha Cushner, Lawrence Beerkircher, Garry Decossas, and Scott Leach) using this form (https://forms.gle/kiMGRfUwbKJCf8Vs6). SEFSC statistician Garry Decossas completed the data pull based on submissions to the SOE from previous years, and provided the data to HMS staff. Data from the areas (MAB, NEC) and time period of interest (1992-2023) are summarized by species and year. Number of hauls per year are also provided to enable CPUE calculations of species per year. This is a data pull of ALL species reported in these areas, so there is more than just sharks in the dataset.
Code used to process this data for SOE products can be found on Github - NOAA-EDAB/ecodata.
