Example of Surgically Tagging a Fish with an Acoustic Tag for Fisheries Research

Scientists surgically implant a fish with acoustic tags in order to monitor survival, passage, and behavior in detail. This provides better information for better fisheries management (e.g., for salmonids populations, as well as numerous other species). Once tagged, the fish are distributed in their aquatic environment and their behavior is monitored in high-resolution (to 20 cm) in 2D and 3D. Literally hundreds of fish are simultaneously tracked and monitored in one area at one time which provides scientists and researchers the data they need to meet study objectives. Often times, new questions arise as additional behavioral data becomes apparent (e.g., responses to unique environmental dynamics or detected predator-prey events). Typically, tag surgeries take minutes, includes two su
