Long Term Resource Monitoring (LTRM) electrofishing techniques: An addendum to the methods outlined in Ratcliff et al. (2014)

This document provides clarifications related to field procedures for the fisheries component of the Long Term Resource Monitoring (LTRM) element of the Upper Mississippi River Restoration (UMRR) program. Our goal is to clarify procedural field nuances for day electrofishing methods and sampling under LTRM fish component procedures and protocols (Ratcliffe et al. 2014). The need to document such nuances was realized at the 2023 UMRR LTRM fish component field practicum, held in May 2023 at Western Illinois University’s Kibbe Biological Station in Warsaw, Illinois, following cross agency field training and practice. As such, this document should be considered an addendum to the existing standardized field procedures for the UMRR LTRM fish component (Ratcliffe et al. 2014). Moreover, this content should be incorporated into the next update to the fisheries procedure manual.
