Juvenile Trout - Electrofishing Intro |
Electrofishing is the method of choice for collecting such information. Once fish have been captured, they are identified to species, examined for possible signs of whirling disease, measured and then released. This type of survey is intended to yield estimates of abundance as well as information regarding species composition, size distribution and habitat utilization. |
Fluvial cutthroat trout are known to spawn in Fox Creek and Teton Creek, two major tributaries to the Teton River. Little is known about the distribution of juvenile cutthroat trout within these streams, or within several other potential spawning tributaries throughout the Teton valley. The goal of the electrofishing survey is to investigate the spatial distribution and abundance of age-1 and young-of-the-year Yellowstone cutthroat trout in these tributaries. More quantitative and spatially diverse data regarding the patterns of YOY and juvenile cutthroat trout abundance are needed to better assess the current status of cutthroat trout in the Teton Valley.
