Through key regional collaborations with the Pacific States Marine Fisheries Commission, Oregon Department of Fish and Wildlife, Alaska Fisheries Science Center, and the fishing industry, the Marine Habitat Ecology Team at the NWFSC has been able to pursue a wide-ranging array of conservation engineering projects relevant to reducing bycatch in the west coast groundfish and ocean shrimp trawl fisheries. Examples of types of research projects pursued during any given year include: 1) Reducing Chinook salmon, eulachon, rockfish, and Pacific halibut bycatch in midwater and bottom trawl fisheries using Bycatch Reduction Devices (BRDs), 2) Examining selectivity characteristics of codends that differ in mesh size and configuration in bottom trawl fisheries, and 3) Testing other novel bycatch engineering modifications to mobile and fixed gears. Much of our current work has been in response to the fishing industries concerns over catches of overfished and rebuilding rockfishes and Pacific halibut allocated in the Pacific coast Groundfish Trawl Rationalization Catch Share Program. The trawl rationalization program, starting in January 2011, established formal Annual Catch Limits (ACLs) and individual catch share quotas. In addition to ACLs, fishing opportunities may also be limited by hard caps or IBQs for non-groundfish species (e.g., Chinook salmon, and Pacific halibut). Bycatch of overfished and prohibited species in the west coast groundfish trawl fishery has the potential to constrain the fishery such that a substantial portion of available harvest may be left in the ocean.

Goal 1: Improve understanding of salmon ocean ecology by integrating stock-specific distribution patterns over space and time with biological and environmental data. Goal 2: Integrate multiple disciplines to develop and apply new scientific technology to improve fisheries management strategies across geo-political boundaries. Goal 3: Improve economic opportunities for fishermen and coastal communities. The Oregon Salmon Commission, California Salmon Council, and Washington Trollers Association lead the Collaboration. Partners include Oregon Sea Grant, Community Seafood Initiative, Columbia River Inter-Tribal Fish Commission, University of California Santa Cruz, Oregon State University, Oregon and Washington Departments of Fish and Wildlife, California and Idaho Departments of Fish and Game, National Marine Fisheries Service Northwest, and Southwest Fisheries Science Centers. Fishermen sample Chinook salmon at sea. Genetic Stock Identification (GSI) analysis is used to determine stock of origin. Scales are examined to determine age, and other biological and physical data are taken. The purpose is to develop Fishery information system with multiple goals. The target audience is the Pacific Fishery Management Council (PFMC) and Pacific Salmon Commission (PSC) Management, as well as fishermen, scientists, marketers, educators, and the general public. This is a stand-alone project, with one principal point of contact in NMFS. This project is ongoing. Chinook genetics for stock identification.

This system collects bycatch data and fishery landings data from all five NOAA Fisheries Regions and automates the generation of the tables required to publish the National Bycatch Report (NBR). The NBR documents bycatch estimates, using observer data and self-reported logbook data, for all fisheries for which this information is available. NBR bycatch estimates are fishery- and species-specific. The NBR includes bycatch estimates for fish, marine mammals, sea turtles, seabirds, and corals. Future NBR reports will include additional bycatch estimates as new fisheries are monitored and new data are analyzed. Over time, the NBR, along with other information sources, should help improve NOAA Fisheries' ability to monitor bycatch trends, improve stock assessments, and set fishery monitoring priorities, as well as serve as a useful data tool for NOAA Fisheries' management partners.

NOAA Fisheries and its partners conduct fisheries-independent surveys in 8 regions in the US (Northeast, Southeast, Gulf of Mexico, West Coast, Gulf of Alaska, Bering Sea, Aleutian Islands, Hawai’i Islands). These surveys are designed to collect information on the seasonal distribution, relative abundance, and biodiversity of fish and invertebrate species found in U.S. waters. Over 900 species of fish and invertebrates have been identified in these surveys.

Fishery Independent Survey System (FINSS) is a national system that characterizes NMFS ocean observation activities, stock and ecosystem data collections during fishery-independent surveys conducted by NMFS Science Centers.

The National Marine Mammal Laboratory (NMML) a division of NOAA's Alaska Fisheries Science Center (Seattle, WA) and Cascadia Research Collective (Olympia, WA) conducted aerial and small boat line transects to estimate the abundance of harbor porpoises in waters of Oregon, Washington, and British Columbia, Canada. This dataset contains line transect survey data with effort (line length) and sighting data (species, group size, distance/angle) and associated covariate data.

This layer is intended to represent information collected during NOAA Fisheries’ California Current Ecosystem Survey. The California Current Ecosystem Survey started in 2006 and is led by NMFS Southwest Fisheries Science Center. This survey monitors West Coast coastal pelagic fish species (CPS) including the northern and central sub-populations of Northern Anchovy, the northern subpopulation of Pacific Sardine, Jack Mackerel, Pacific Mackerel, Pacific Herring, their prey items, and the biotic and abiotic environments of the California Current Ecosystem. These data are used to estimate the distribution, biomass, and demographics of species of interest to inform stock assessments. The CCES survey typically occurs annually between July and September on the West Coast of the U.S. and Canada, with a recent expansion into Mexico thanks to a collaboration with the Instituto Mexicano Investigación en Pesca y Acuacultura Sustentables (IMIPAS, formerly INAPESCA). During the day multifrequency, scientific echosounders, a continuous underway fish egg sampler (CUFES), and an underway conductivity-temperature-depth (UCTD) probe are all used to collect data. At night, surface trawls are conducted in locations where coastal pelagic species were observed acoustically during the day. The trawls serve to estimate the species composition and demographics of the fishes sampled acoustically during the day. In recent years, sampling from NOAA ships has been augmented with acoustic sampling by unmanned surface vehicles (Saildrone USVs), and with acoustic and purse-seine sampling from industry fishing vessels off WA, OR, and CA. The sampling from fishing vessels expands the survey into areas that are inhabited by CPS but are too shallow for the NOAA ships to safely navigate.

This layer is intended to represent the geographic extent of NOAA Fisheries’ Integrated West Coast Pelagics Survey. The Integrated West Coast Pelagics Survey started in 2025 and is a jointly led effort by the Northwest and the Southwest Fisheries Science Centers. The Pacific hake and coastal pelagics fisheries rely on data collected through NOAA surveys and the fisheries. These data are essential for tracking our changing environment and creating accurate stock assessments that ensure these fisheries remain productive and sustainable today and in the future. Previously, two fishery independent surveys were conducted to gather data on these crucial West Coast fisheries, the Joint U.S.-Canada Integrated Ecosystem and Pacific Hake Acoustic Trawl Survey and the California Current Ecosystem Survey. Combining these two surveys into the Integrated West Coasts Pelagics Survey is an opportunity to ensure we collect the data we need and improve how we survey, including accounting for evolving oceanic/ecosystem conditions. Notably, an integrated survey maintains the integrity of the CPS and Pacific hake biomass time series to help meet industry needs.
