Separation By Code

 

 

The PIT tag Separation by Code (SbyC) process allows researchers to target individual tagged fish and separate them from the general population as they move through juvenile and adult fish passage facilities that are equipped with PIT tag actuated gates.

By default, all PIT-tagged fish are returned to the river at each of the juvenile fish bypass sites unless a researcher requests a different disposition for a particular group of fish. Target fish can be collected in a holding tank for hands-on sampling, or the default gate actions can be over-ridden so that they follow the same route as the untagged population of fish.

SbyC actions can be applied to an entire population of tagged fish, a proportion of that population, or a predefined number of individuals. Both daily and seasonal collection quotas can be set to limit the number of fish sampled. Each SbyC action can be scheduled for a specified number of hours or days, or a specified pattern of days. Multiple populations can be identified and segregated at a given site, with unique SbyC actions assigned to each group at that site. Please refer to the descriptions and diagrams for details regarding the PIT tag Separation by Code capabilities at the various juvenile and adult passage facilities.

To request a new Separation by Code project, go to the Separation by Code request page under the Services menu. Click the Request new SbyC project button to get started on the process.

TAG DISTRIBUTION INVENTORY

The Tag Distribution and Inventory (TDI) application is used to request PIT tags for projects funded by the Bonneville Power Administration (BPA). If you are a point of contact for a BPA project and would like to request PIT tags, log in and click the Manage Requests button in the left-hand menu. Please view the video tutorial below, or read the step-by-step instructions, for details on how to complete and submit your request for PIT tags.

For more information about receiving PIT tags for BPA projects, please contact Sharon Grant (sdgrant@bpa.gov).

FORECASTER

In response to elements contained in the 2008 BiOp, the Action Agencies (AA), NOAA and the NPCC determined that a means to forecast future PIT-tagging effort would be instructive and should be established. Ideally, the forecast should extend several years into the future. A sub-group was formed that specified attributes to be included in a database that would inventory and forecast future tagging efforts. In December 2009 a template for a new PIT tag forecast-inventory was constructed and distributed to all agencies to populate. Until recently the database was resident at UW CBR. The agencies felt it would be advantageous to integrate the Forecaster into PTAGIS and make it more user friendly. As of October 2013, a version is now in place on the PSMFC system.

Drop-down menus are provided for many parameters; use them where applicable. Some columns are linked together, limiting your choices (e.g., for a given listed ESU, only pertinent MPGs will appear linked back to that ESU).

This forecast inventory is not merely for FWP and AFEP projects. PIT tagged fish released by HCP and BOR funded projects should be included, as well as other relevant efforts that may not fall under these umbrellas. The Region will establish guidelines for including forecast information from all users.

For populations, the ESU or MPG is the target unit. Spatially, the 4th-field HUC (8 digits) is currently the focal point, with ability to specify a PTAGIS release site, if known. The forecaster focuses on Anadromous salmonids but could include other species if needed.
