Summary

These data are the primary data used to model rainbow trout growth in Glen Canyon. Fish growth data were collected from nighttime boat electrofishing field campaigns conducted five to six times per year in April, July, September, and January, from April 2012 through November 2021 for a total of 9798 observations of mark-recapture-based growth. Sampling was conducted in a five km reach in the lower portion of the Glen Canyon tailwater (3.7-8.9 km upstream of Lees Ferry, AZ). Two nights of sampling occurred on each trip, with the central 2-3 km of the reach sampled on both nights. After capture, fish were kept in aerated 40-L buckets and transported to a central processing location. Groups of 10-15 fish were anesthetized and rainbow [...]

Purpose

The purpose of these datasets is to quantify the relative importance of flow experiments vs water quality on somatic growth of rainbow trout (Oncorhynchus mykiss) in the Colorado River below Glen Canyon Dam. Rainbow trout is a freshwater salmonid that supports many recreational fisheries but is also included in the global list of the top 100 worst invasive species (Global Invasive Species Database 2018). Improved understanding of factors that affect somatic growth rates, abundance, and distribution of this species would help manage fisheries and the impacts of numerous introductions on native fish; particularly endangered species. Somatic growth is a potentially important process controlling fish populations since it can affect survival, sexual maturity, and reproductive success. Making these research datasets accessible to the broader public and research community potentially benefits future research by allowing for reanalysis and alternative analysis yet explored. Hopefully, presenting these original data will facilitate the development of collaborative efforts and provide data sources for educational research and analytical training.
