Acoustic telemetry data (Vemco, Inc) were collected on invasive silver carp (Hypophthalmichthys molitrix), bighead carp (H. nobilis) and their hybrids in the upper Mississippi River (navigation pools 15-19) to determine movement patterns and preferred habitats during September 2013 through November 2017. We consolidated these data into intervals of fish within-pool residency and intervals of fish transitions into adjacent navigation pools (i.e., dam passages). The combined data set was then parsed into an "upstream passage" data set (in which downstream passage intervals were censored) and and a "downstream passage" data set (in which upstream passage intervals were censored). We then examined the effects of river hydrology and water temperature on dam passages by bigheaded carps using a complementary log-log model for continuous-time processes to estimate a Cox proportional hazards regression model (Allison 2010).
