We have been using and continue to use acoustic telemetry methods to monitor the movement behavior and define habitat use of groundfish species in and out of Puget Sound waters. Detections of individual fishes has been collected at small and large scales over short and long term periods. We have data on sixgill and sevengill sharks, spiny dogfish, lingcod, copper, quillback, yellowtail and black rockfish, and spotted ratfish. These data are being used to describe the spatio-temporal patterns of behaviors expressed by top predators and other important members of the groundfish community in Puget Sound and along the West Coast. We intend for this information to inform the strength of inter- and intra-specific interactions quantified by ecosystem-scale models as well as the development of models used to determine the efficacy of spatial management strategies such as Marine Protected Areas. This has been a research topic since 2003, and will continue with work on listed species such as yelloweye and canary rockfish. Acoustic telemetry data for rockfish in Puget Sound, primarily copper and quillback.

The core function of the Resource Assessment and Conservation Engineering (RACE) Division is to conduct quantitative fishery surveys and related ecological and oceanographic research to measure and describe the distribution and abundance of commercially important fish and crab stocks in the eastern Bering Sea, Aleutian Islands, and Gulf of Alaska. This includes measuring the abundance of fish (including rockfishes) in rocky untrawlable areas. To accomplish this, we are developing acoustic-optic surveys for rockfishes. These data area stored as image files and acoustics files.

This is a fishery-independent survey that collects data on reef fish in southeast US waters using multiple gears, including chevron traps, video cameras, ROVs, longlines, and acoustics. This project is also collecting information on hardbottom habitats using video cameras, ROVs, and acoustics gears.

Integrated acoustic and trawl surveys are used to assess the distribution, biomass, and biology of Pacific hake along the Pacific coasts of the United States and Canada. Scientists from the Northwest Fisheries Science Center (NWFSC) and Department of Fisheries and Oceans-Canada are responsible for conducting the survey. The survey consists of a series of transects that are oriented generally east-west, and are spaced at a nominal 10-nautical mile interval. Sea depth at the nearshore end of individual transects is typically 50 m; offshore extents are typically at a depth of 1,500 m. Geographical coverage extends from near Morro Bay, CA north to Dixon Entrance. Acoustic data are collected during daylight hours with a Simrad EK60 scientific echo sounder coupled with the ER60 software system. Trawl samples from pelagic and bottom trawls are used to classify the observed backscatter layers to species and size composition and to collect specimens of Pacific hake and other organisms. Analysis of acoustic data involves identification and delineation of backscatter layers that are attributed to Pacific hake. The biomass estimate and length-at-age composition of Pacific hake generated from this survey are used in analysis and management of the stock. This survey is conducted on a biennial basis. There is a firm deadline for producing the biomass estimate in the middle of the December following the survey. Biological data collected from FSCS during catch processing.

This database is used to hold tracking data for green sturgeon tagged in Central California. The data collection began in late 2002 and is ongoing.

This geodatabase contains spatial data for NOAA's West Coast Region (WCR) Groundfish Conservation Areas (GCA). GCA's are conservation areas created or modified and enforced to control catch of groundfish or protected species (https://www.ecfr.gov/current/title-50/chapter-VI/part-660/subpart-C/section-660.11).The geodatabase contains the following feature datasets, each containing feature classes that depict the spatial representation of a GCA:YRCA - Yelloweye Rockfish Conservation AreasGEA -Groundfish Exclusion AreasCCA - Cowcod Conservation AreasRCA - Rockfish Conservation AreasWithin each feature dataset, the feature class naming convention reflects the 1) type of area (YRCA, GEA, CCA, or RCA), 2) the name of the area and 3) the date (YYYYMMDD) that the conservation area was published in the Federal Register (FR).

The broad scope of the Essential Fish Habitat (EFH) mandate requires an efficient process for describing and mapping the habitat needs of federally managed species. For example, research indicates surficial sediments affect the distribution and abundance of many groundfish species, yet traditional sampling with grabs and cores is impractical over areas as large as the Bering Sea shelf. Acoustic tools are suitable for large-scale surveying and show great promise as a substitute for direct-sampling methods, but they have not been proven useful for EFH purposes.

Marine protected areas (MPAs) can be highly effective tools for conserving habitats, populations, and sustainable fisheries. The National Park Service (NPS) is hosting a collaboration of researchers assessing effectiveness of MPA boundaries, species movements, and identifying gaps in protection for a wide range of shark, turtle, and reef fish species. Building upon our previous work, we're tagging queen conch to examine time spent in protected areas, migrations to open fishing areas, spawning grounds, and nursery habitats.
