Yackulic, C.B., 2018, Humpback Chub (Gila cypha) and Rainbow Trout (Oncorhynchus mykiss) Joint Mark-Recapture Data and Model, Colorado River, Arizona: U.S. Geological Survey data release,


These data were compiled for a joint mark-recapture analysis of humpback chub and rainbow trout and include capture histories for both species, as well as environmental covariates associated with monthly time steps used to measure survival and growth and environmental covariates used to predict capture probability during each sampling trip. This worksheet also include parameter estimates and associated variance-covariance matrix from a prior analysis, which were combined with the output from the joint mark-recap analysis to predict equilibrium adult abundances under a variety of scenarios.

These data were collected as part of monitoring of humpback chub and rainbow trout in the Colorado River in its Grand Canyon Reach. Monitoring is designed to answer questions about the relative importance of various factors in the population dynamics of humpback chub and to measure the state (i.e., abundances) of various size classes of humpback chub in the Colorado River to inform adaptive management.
