Yellowstone Cutthroat Trout and Brown Trout diet data from Duck Creek, MT in summer and fall 2015

공공데이터포털

We collected diets on Yellowstone cutthroat trout (Oncorhynchus clarkii bouvieri) and brown trout (Salmo trutta) above (Yellowstone cutthroat trout allopatry) and below (Yellowstone cutthroat trout sympatry with brown trout) a natural barrier in Duck Creek, Montana. We used gastric lavage methods to collect diets, and samples were placed in storage containers and taken back to our lab and frozen until sorting. All samples were sorted by Rhithron, Inc. (Missoula, MT) with individuals identified down to the order.

Lake Huron Angler-Caught Predator Diets, 2017-2018

공공데이터포털

This tabular data set contains information about the diets of angler-caught Lake Trout (Salvelinus namaycush), Walleye (Sander vitreus), Chinook Salmon (Oncorhynchus tshawytscha), Coho Salmon (O. kisutch), Atlantic Salmon (Salmo salar), Steelhead (O. mykiss), Pink Salmon (O. gorbuscha), and Brown Trout (Salmo trutta) captured between April and October of 2017 and 2018 from U.S. waters of Lake Huron. Diet items were identified to lowest taxa, enumerated, measured, and prey biomass determined.

Macroinvertebrate and redband trout (Oncorhynchus mykiss newberrii) diet data for watercourses in the Goose Lake Basin, Oregon, U.S.A., 2024

공공데이터포털

We collected aquatic macroinvertebrate and redband trout (Oncorhynchus mykiss newberrii) diet data in the Oregon portion of the Goose Lake Basin. Data were collected by the U.S. Geological Survey (USGS) and Oregon State University (OSU) to monitor prey communities in the Basin, and to relate observed prey abundances to specific habitat features. Sampling was conducted based on previous survey efforts, using a stratified random subset of sites surveyed by ODFW in 2007 and OSU in 2022-2024. Macroinvertebrate sample processing was carried out by R. Roper and R. Ponce Velez at OSU and diet samples were processed by Aquatic Biology Associates in Corvallis, Oregon. These data are part of a broader, comprehensive monitoring effort in the Basin.

Environmental DNA data, fish abundance data, and stream habitat data from northwest Montana and northeast Washington and southern British Columbia, Canada

공공데이터포털

Field estimates of the abundance of two trout species (bull trout and westslope cutthroat trout) in Montana and rainbow trout in Washington and British Columbia were collected in concert with environmental DNA samples (eDNA) to evaluate if eDNA copy numbers correlated with abundance of trout. In addition, stream habitat data including channel units (pools, riffles), substrate, large woody debris, among others, were collected at sites.

Juvenile lake trout (Salvelinus namaycush) diets from annual Lake Huron fall bottom trawl surveys (2008-2017)

공공데이터포털

Diet analyses were performed on juvenile lake trout (Salvelinus namaycush) captured by bottom trawl during annual USGS Great Lakes Science Center demersal fish community surveys in mid-October to mid-November 2008–2017 in Lake Huron. This dataset contains lake trout capture information (e.g., location, depth) and diet item data (taxa consumed and their associated lengths).
