Movement and dispersal of migratory fish species is an important life history characteristic that can be impeded by navigation dams. Although habitat fragmentation may be detrimental to native fish species, it can act as an effective and economical barrier for controlling the spread of invasive species in riverine systems. Today's river managers are faced with the conundrum of balancing the pros and cons of connectivity in aquatic systems. Fish deterrent technology has been proposed as a potential barrier at pinch-point dams to assist in eradicating or reducing invasive species range expansion on the Upper Mississippi River (UMR). Lock and Dam (LD) 15 is infrequently at open river conditions and has been considered a potential location for placement of a deterrent. Prior to deployment of a deterrent, preliminary movement data of native and invasive fish species (i.e., paddlefish, bighead carp, silver carp) at LD 15 is necessary to understand invasive species behavior while permitting native fish passage. My objectives were to evaluate fine scale movement of paddlefish and bigheaded carps by 1) evaluating the environmental conditions and lock operation associated with the presence (i.e. residency and presence events) of bigheaded carp and paddlefish in the downstream approach of LD 15 using generalized linear mixed-effects models (GLMM) and generalized linear models (GLM), 2) distinguishing weekly, diel and seasonal patterns for bigheaded carp and paddlefish residency below LD 15 approach, and 3) identifying the relationships between lock operations and upstream or downstream passages. I observed 133 bigheaded carp residency events from 15 individuals and 533 paddlefish residency events from 42 individuals downstream of LD 15. I observed a difference in residency duration GLMM between bigheaded carp and paddlefish. Bigheaded carp residency duration was influenced by the number of recreational vessels moving downbound, temperature, and season. Paddlefish residency duration was influenced by temperature, the number of commercial barges and recreational vessels moving downbound and the number of commercial barges and recreational vessels moving upbound. The presence event GLM indicated that temperature, year, hydraulic head, and the number of commercial barges and recreational vessels moving upbound were all important factors for bigheaded carp and paddlefish presence events. The most important factors for bigheaded carp presence events were the number of commercial barges and recreational vessels moving upbound, hydraulic head, temperature, and year. The most important factors for paddlefish presence events were temperature, hydraulic head, number of commercial barges and recreational vessels moving downbound, number of commercial barges and recreational vessels moving upbound, year, and season. My data did not indicate variable diel patterns between bigheaded carp and paddlefish. Paddlefish seasonally used the lock approach in April through May. I documented two upstream passages by a single bigheaded carp and two paddlefish through the lock chamber at LD 15 during my study. Three upstream passages coincided with the upstream-bound lockage of commercial barges and one passage occurred with an upstream-bound recreational vessel. I documented four passages of bigheaded carp and 22 passages of paddlefish during my study. Nearly all of my upstream passages for both species occurred during open river conditions when hydraulic head was low (< 1.0 m). Findings from my study suggest that the deployment of a deterrent at LD 15 would not be a completely effective stand-alone device for the prevention of bigheaded carp upstream passage. Understanding fish behavior at pinch-point dams is a critical information need for river managers as they evaluate potential tools or technologies that may assist in slowing or ceasing the upstream expansion of bigheaded carp in the UMR.
