STREAMNET DATA STORE

Add Your Data Set


Use our Data Publishing Service to add your data set to the Data Store.

The StreamNet Data Store is a searchable archive of data sets related to fish and other aquatic resources that are not of the specific data types included in the main StreamNet database. These data sets come from many different sources and are provided for download in their original formats. To add your own data set to the Data Store, use our Data Publishing Service.

StreamNet did not participate in creation of most of these data sets, and we are not able to answer questions about those we did not help develop. For questions about the data sets available from this page, please contact the originator of the particular data set.

To search the Data Store, enter key words, project numbers, species, methods, etc. into the search box below and click "Search".

Purpose of Data Set One of the recovery goals for this population is to designate the section of the Snake River above its confluence with the Salmon River as a natural production area. Ideally this section would eventually contain only natural-origin fish. To monitor progress toward that goal, spawners are sampled and analyzed using parentage-based tagging (PBT) to determine the proportions of hatchery and natural fish on the spawning grounds.
