Is motivation important to brook trout passage through culverts?: Culverts can restrict movement of stream-dwelling fish. Motivation to enter and ascend these structures is an essential precursor for successful passage. However, motivation is challenging to quantify. Here, we use attempt rate to assess motivation of 447 brook trout (Salvelinus fontinalis) entering three culverts under a range of hydraulic, environmental, and biological conditions. A passive integrated transponder system allowed for the identification of passage attempts and success of individual fish. Attempt rate was quantified using time-to-event analysis allowing for time-varying covariates and recurrent events. Attempt rate was greatest during the spawning period, at elevated discharge, at dusk, and for longer fish. It decreased during the day and with increasing number of conspecifics downstream of the culvert. Results also show a positive correlation between elevated motivation and successful passage. This study enhances understanding of factors influencing brook trout motivation to ascend culverts and shows that attempt rate is a dynamic phenomenon, variable over time and among individuals. It also presents methods that could be used to investigate other species’ motivation to pass natural or anthropogenic barriers.

Official summary from the FWS Fish Passage Summit: Please find attached the workshop proceedings from Partner Workshop: Fish Passage through the Bipartisan Infrastructure Law that took place at the National Conservation and Training Center from July 18-20. The document includes the following: Overview of each of the sessions and speakers on Day One and summary of post session discussion. Detailed brainstorming from all the breakout sessions on Day Two Synthesis and discussion from Day Three Meeting Agenda List of Attendees (in person and virtual) These are not decisional documents, rather a synthesis of information, ideas, and perspectives. We hope it will serve as a reference document to support all our efforts into the future.
