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.

Upper Flathead River system hybrid and rainbow trout spawning movements

Purpose of Data Set See Contract Summary.
Summary / Abstract This data set contains movement information from hybrid (westslope cutthroat trout x rainbow trout) and rainbow trout captured by jet boat-based electrofishing during spring of 2016, 2017 in the upper Flathead River system. Fish were implanted with radio telemetry transmitters and tracked to identify spawning locations, site fidelity, and habitat use, thereby helping to evaluate the efficacy of suppression efforts and informing our knowledge of introgression sources.

Broad Category of Methods Field
Data Collection Methods During March 2016, 30 hybrid and rainbow trout within the upper Flathead River system were captured and implanted with radio telemetry tags. Identification of hybrid or rainbow trout was based on morphological characteristics, including body shape, spotting pattern, the presence and condition of red or orange slashes ventral to gill covers, and body coloration (Behnke 1992). Fish were targeted in the Mainstem Flathead River during March and early April, immediately prior to the spawning period of May-June to allow for reliable determination of spawning likelihood. Fish were captured using jet-boat electrofishing (Steed et al. 2017). Fish were anaesthetized using tricaine methane sulfonate (MS-222) and measured for length (mm) and weight (g). Captured fish meeting the 2% transmitter weight-to-body-weight ratio (Winter 1996) were surgically implanted with Lotek MCFT2 radio telemetry tags weighing 8.0g (air weight), using the 148.740 MHz frequency, with a 5 second burst rate, and according to methods described by Muhlfeld et al. (2003), using staples rather than sutures. Tags were programmed to run continuously for 632 days and were equipped with motion sensors, transmitting a different code if tags were sedentary for 24 hours or more. Passive integrated transponder (PIT) tags were administered during surgery as a double mark to obtain growth information in the event of future capture. Fin clips were also collected for genetic analyses and preserved in 95% ethanol.
