These data represent a set of capture histories of rainbow trout (Oncorhynchus mykiss or RBT) captured in the Colorado River (CR) and(or) detected on the multiplexer array in the Little Colorado River (LCR). Capture trips to the Colorado River occurred in April 2012, July 2012, September 2012, January 2013, April 2013, July 2013, September 2013, January 2014, April 2014, July 2014, and September 2014. Rainbow trout were detected on the PIT array system (MUX) from October 2013 - April 2014.

These capture histories were imported as data and used to fit a mark-recapture model that estimated movement, abundance, and survival of rainbow trout. These data were then used to estimate abundance of rainbow trout (both marked and unmarked) that entered the Little Colorado River from October 2013-April 2014. Knowing the number of rainbow trout that entered the LCR is important for conservation efforts of endangered humpback chub (Gila cypha), as rainbow trout are a non-native species that predates upon and competes with humpback chub.
