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 whitespotted ratfish.

Tag juvenile Columbia River steelhead in the Columbia estuary with acoustic tags to determine their marine distributions. This was a small pilot project to test our ability to 1) use fish collected by the Columbia Estuary Purse Seine project as a source for tagging, 2) use a mobile tagging station to tag 100 fish, and 3) perhaps get some detections at various fixed and mobile receivers in estuarine and marine waters. While many fish were detected leaving the estuary, only one was detected in marine waters off Willapa Bay. Since this is a pilot project, no reports were produced. Field data fisheries independent survey. This project was foronly 1 year and no longer exists.

The Central Valley Angler Survey, or CVAS, monitors sport fisheries in the Sacramento River system, from the Carquinez Strait to Keswick Dam near Redding, and on the lower Mokelumne, Yuba, Calaveras, American, and Feather rivers. CVAS was a year-round survey from 1991-1994, 1998-2002, and 2006-2016, and included the Yuba and Calaveras rivers during portions of those periods. During fiscal years (FY) 2017-2020, CVAS was scaled back to a 5-1/2 month survey, focused on the Chinook Salmon sport fishery from July 16 through December 31, but resumed year-round surveying beginning FY 2021. Data are collected to estimate angler effort, catch, and harvest of key species using expansions of spatially and temporally stratified data. Data collected from 1991 through 2016 were used to generate estimates of fishing effort, catch, and harvest of Chinook Salmon, steelhead trout, Rainbow Trout, White Sturgeon, Sacramento Splittail (2007-2016), Striped Bass, and American Shad. During fiscal years 2017-2020, CVAS focused only on generating estimates of fishing effort, catch, and harvest of Chinook Salmon in support of the West Coast Chinook Salmon management process. Data collected are based on eight survey runs per month in each of 24-27 survey sections that cover the entire survey area. Data include counts of boats and angling parties in each survey section to estimate fishing effort on a daily timestep. Data are also collected during angler interviews and include information about individual angler effort, and biological data on the catch. Heads are collected from Chinook Salmon that possess a clipped adipose fin to recover coded-wire tags that provide information about the hatchery origin of the fish. Biological information collected on the catch of anglers encountered by survey staff. Data includes location, species, length, weight, any external markings or tags observed, scale sample collection information, and sex of fish. This data and metadata were submitted by California Department of Fish and Wildlife (CDFW) Staff though the Data Management Plan (DMP) framework with the id: DMP000421.

The Strait of Juan de Fuca Intensively Monitored Watershed (IMW) began in 2004 to test the watershed-scale response of steelhead and coho salmon to watershed restoration. The Strait IMW includes two treatment watersheds (East Twin River and Deep Creek) and one control watershed (West Twin River). Restoration treatments included LWD placement, road and culvert removal, off-channel habitat creation, and riparian planting. Monitoring of physical habitat as well as coho and steelhead parr densities began in 2004 using the EPA’s EMAP site selection and sampling protocols. Smolt and adult monitoring predates the IMW program and began as early as 1998 in some watersheds. Preliminary results suggest an increase in pool habitat and small increases in steelhead adults and smolts in East Twin River, as well as adult coho in Deep Creek. PIT tagging has revealed a large outmigration of age-0 coho in the fall that contributes to the adult return, stream swapping by juveniles, and varying return times for coho adults. Current research has answered a portion of our original questions and has raised new ones. Restoration treatments were completed fairly recently or are still in progress. As habitat typically does not respond immediately to treatment, additional years of monitoring are needed to determine watershed-scale fish response. Moving forward, analysis of otoliths to validate PIT tag data and new restoration methods such as carcass or nutrient enhancement may be merited. PIT tagging and habitat data. Includes fish weight, length, location, and PIT tag number. Habitat data includes wood measurements and stream surveys.

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.

Annual telemetry data are collected as part of specific projects (assessments within watersheds) or as opportunistic efforts to characterize Atlantic salmon smolt migration dynamics. Telemtry projects have since expanded to include the tracking of a variety of non-Atlantic salmon species.

To determine movements of green turtles in the nearshore foraging areas, we deployed acoustic tags and determined their movements through active and passive acoustic telemetry in San Diego Bay and the Long Beach area.

Cowcod are the primary species that have influenced groundfish regulations since 2001 in California waters. More progressive management approaches have been adopted during this time, and many rockfish species, including cowcod, now appear to be rebuilding. This rebuilding has recently translated into increased cowcod catches by both recreational and commercial fishers, and the use of descending devices has become a popular method for releasing these fish with as little harm as possible. However, post-release mortality of cowcod associated with the use of these descending devices is still unclear. We have tagged __ adult individuals using acoustic telemetry methods, and analyses of these movement data are currently underway. We will also tag juvenile and sub-adult cowcod in an effort to estimate size-dependent post-release mortality and movement patterns. This will give us a better understanding of the rebuilding status of the species, and how changes in fishing regulations might affect this rebuilding.
