NWFHS Case Report Metadata
  • Description:
  • The Case Report is available for each NWFHS case. A case is defined as a group of samples collected in a single effort at a single location. Multiple species may be included in a single case.
  • Available Formats:
  • HTML: Web Page. Viewable in web browser.
  • PDF: Portable Document Format. Viewable using software capable of reading PDF files, such as Adobe Reader.
  • Layout:
  • Layout Description The Case Report layout.
  • Attribute Descriptions:
    • Case Information: General background information for the case.
    • Lab: USFWS Fish Health Center responsible for managing the case.
    • Partner Agency: Primary organization collaborating on case, usually assisting with sample collection
    • Case Number: Unique identifier assigned to each case by managing USFWS Fish Health Center
    • Tracking Number: Optional case identifier
    • Type of Sampling: Indicates whether sample collection was routine or motivated by a particular purpose, such as investigating a fish kill, that might have suggested unusual circumstances (diagnostic).
    • Date Collected: Date of sample collection
    • Date Received: Date samples were received by the USFWS Fish Health Center
    • Date Completed: Date case was completed
    • Site Description: Description and characteristics of the sample site.
    • Waterbody Name: Name of the geographic feature sampled as designated by the U.S. Board on Geographic Names
    • Site Name: Sample site identifier(name) assigned at the time of sample collection
    • Site Description: Supplemental description of the sample site
    • Water Temp.: Sample site water temperature in degrees Celsius at the time of collection
    • Spatial Information: Attributes associated with the geographic location of the sample site.
    • GNIS Id: Permanent and unique feature record identifier that is assigned to the sampled geographic feature by the U.S. Board on Geographic Names
    • Latitude: The latitude of the sample site
    • Longitude: The longitude of the sample site
    • Datum: The geodetic reference system used to determine the latitude and longitude of the sample site
    • Elevation: The elevation of the sample site in meters
    • State Name: Name of the state where sample site is located
    • County: Name of the county in which sample the site is located
    • HUC 8-digit: 8-digit hydrologic unit code (HUC) of the watershed that contains the sample site location.
    • HUC Name: Name associated with the 8-digit hydrologic unit code (HUC)
    • Sample Information: List of all samples(species) associated with the case.
    • Common Name: The common name of the sampled species
    • Code: The three-letter code representing the sampled species. The code is assigned and maintained by the USFWS National Fish Health Database Coordinator.
    • Species: The full scientific name of the sampled species
    • ITIS TSN: Taxonomic Serial Number, the unique identifier assigned to the sampled species in the Integrated Taxonomic Information System (ITIS)
    • Number Collected: The number of individual animals collected of the species
    • Collection Method: The collection method used to obtain species samples
    • Assay Results: Results of assays grouped by sample type.
    • Species Code: The three-letter code representing the sampled species. The code is assigned and maintained by the USFWS National Fish Health Database Coordinator.
    • Specimen: The tissue, or combination of tissues, collected from the sample
    • Number Tested: The total number of individual samples (animals) from which the associated specimen was taken for the indicated assay(s)
    • Preliminary Assay: This is the first method that is applied to specimens being tested. The current list of preliminary methods is available in the NWFHS Laboratory Procedures Manual.
    • Corroborative Assay: This is the second method that might be used to test a specimen when the preliminary procedure indicates the possible presence of a pathogen. The current list of corroborative methods is available in the NWFHS Laboratory Procedures Manual.
    • Pathogen Detected: The pathogen that was detected in the specimen by the preliminary assay and confirmed by the corroborative assay.
