Water quality data - North Puget Sound Chinook salmon captive propagation
공공데이터포털
NOAA Fisheries is a cooperator with the Washington Department of Fish and Wildlife and the Lummi, Nooksack, and Stillaguamish Tribes in a 10-year program to rebuild the South Fork Nooksack River spring Chinook and Stillaguamish River fall Chinook stocks through a captive broodstock program. Nitrate(mg/l), nitrite (mg/l), ammonia (mg/l), pH, temperature (Celsius), and dissolved oxygen (mg/l) are routinely measured for tanks used to culture Nooksack and Stilliquamh Chinook, Redfish Lake Sockeye, and Elwha Pink salmon. Water flow (gpm), water clarity, oxygen (on/off), feeding behavior, and cleaning comments are also noted. Measurements are taken weekly at random, except when scheduling conflicts arise. There can be up to 12 dissolved oxygen samples from Building 22 and up to 17 from Building 13. Additional data collected from 4 liter water samples includes classifying invertebrate content down to order. Fish sloughage, spicules, organic matter, ciliates and crustaceans are qualitatively assessed. Spicule types(s), crustacean type(s) and ciliate type(s) are recorded. A text box for microscope comments is present.
Biological data - Integrated acoustic and trawl survey of Pacific hake off the Pacific Coast
공공데이터포털
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.
Growth, movement and survival - Recolonization of the Cedar River, WA by Pacific salmon
공공데이터포털
The objective of this study is to quantify population, community, and ecosystem level changes as a result of salmon recolonization of the Cedar River, WA above Landsburg Dam. The dam was installed in 1901, blocking the upstream migration of adult salmon and steelhead from about 43 km of river habitat. A fish ladder was installed in 2003 to allow adult salmon passage. We collected baseline data on water chemistry, habitat, and fish populations including resident trout and sculpin populations in 2000-2002. These field surveys have been ongoing since 2000. A mark-recapture study in Rock Creek, the largest tributary available to salmon, was started in 2004 and ended in 2010 to quantify growth, movement, and survival of juvenile coho and resident trout. Two experimental stream studies conducted to quantify salmon carcass effects on resident organisms. PIT data of juvenile coho and resident trout in Rock Creek.
Juvenile Fish Data - Coastwide Cooperative Pre-recruit Survey
공공데이터포털
The Pre-recruit survey project is collaborative involving researchers from the FE Division based in 3 laboratories (Newport, Seattle and Hammond), scientists from the Southwest Fisheries Science Center (Santa Cruz), along with researchers from several universities (Oregon State University, University of Oregon, University of Washington, University of California, Santa Cruz). In concert with a similar SWFSC survey effort through California, the purpose of this project is to conduct annual surveys within the coastal ecosystem off Oregon and Washington to quantify the environmental conditions and biota found along the California Current and to elucidate ecosystem-level processes affecting managed and protected marine resources. This project currently supports three main efforts: 1. An annual sampling regime of the hydrology, plankton, small fish, and predators along transects over the Continental Shelf from Oregon and Washington. This consistent survey has generated significant information on within- and between-year variability in the California Current Marine Ecosystem and has yielded valuable insights into the food web off our coast. 2. Collection of specimens for diet analysis, growth, containment load, and other studies related to the ecology and production of commercially important taxa and their relationships within the food web. 3. Parameters and ecological processes quantified during this effort are used in forecasts involving species, assemblages, and ecosystems and also to parameterize ecosystem models used to evaluate cumulative risks and managerial strategies. We towed a Cobb Trawl at 30 m at all stations.
Derelict Gear - Impacts of derelict fishing gear on marine fauna in Puget Sound and the Northwest Straits
공공데이터포털
Puget Sound and the Northwest Straits have experienced a long history of commercial fishing activity. Although much of this fishing activity no longer takes place, there remains lost and abandoned fishing gear throughout Puget Sound and the Northwest Straits. Derelict gear has the potential to impact marine fauna through entanglement and trapping. Collaborative work of federal, state and tribal agencies with local and regional non-governmental agencies, specifically the Northwest Straits Foundation, has recovered thousands of derelict nets and pots since 2002 and documented their impacts on marine fauna, many of which are of commercial and/or conservation concern.
