“…Electric fish handling gloves (Smith-Root; pulsed DC) were also used to assure sedation and immobilization of Muskellunge for the duration of the surgery (Ward et al 2017;Abrams et al 2018;Reid et al 2019). The gloves transmitted a low-amperage and low-voltage electric current that ranged between 0.016 and 0.0063 A and was independently controlled.…”

The St. Louis River estuary is a designated area of concern by the U.S. Environmental Protection Agency due to severe environmental degradation. The spatial ecology of Muskellunge Esox masquinongy, an indicator species, is uncertain within the estuary and the large, connected water body, Lake Superior. We collected genetic samples and used passive acoustic telemetry to track 60 adult Muskellunge in the St. Louis River estuary and southwestern Lake Superior for 15 months. Genetic analysis revealed that the river is utilized by two genetic strains-Wisconsin (WI) and Minnesota (MN)-and their hybrids. These genetic strains were previously stocked to restore a nearly extirpated population. Muskellunge tended to move upstream in the spring, downstream and into Lake Superior throughout summer, and to the middle river during fall and winter. Males and females spent significantly more time in the upper and lower portions of the river, respectively. Movements were influenced by strain in that hybrids and the WI strain spent more time in the upper and middle river, and the MN strain spent more time in Lake Superior. A random forest model indicated that Lake Superior use was related to strain (the MN strain made up 80% of individuals using Lake Superior) but not sex or body length, highlighting the importance of understanding strain behavior when stocking different strains. Future research should include investigating Muskellunge habitat use (before, during, and after restoration), tracking juvenile Muskellunge, and connecting telemetry data with mark-recapture and stable isotope data. Our results provide new insight into Muskellunge spatial ecology and genetics that can inform management and restoration efforts within and beyond the Great Lakes.

“…Chemical anaesthetics in field settings are not recommended and, as an alternative, the use of low‐voltage electricity is suggested [either as electric gloves (Abrams et al ., 2018) or as a portable electrosedation system unit (Prystay et al ., 2017)]. Low‐voltage electricity has been proposed as an anaesthetic to aid in fish restraint because of relatively short recovery times after exposure ( i.e ., seconds; Vandergoot et al ., 2011; Trushenski & Bowker, 2012; Ward et al ., 2017; Abrams et al ., 2018; Reid et al ., 2019). Indeed, because of its relatively low and transient impacts, electricity is widely used as an anaesthetic in aquaculture ( e.g ., Chatakondi & Kelly, 2019; Nguyen et al ., 2018; Rucinque et al ., 2018; Trushenski et al ., 2017).…”

Blood sampling through the caudal vasculature is a widely used technique in fish biology for investigating organismal health and physiology. In live fishes, it can provide a quick, easy and relatively non-invasive method for obtaining a blood sample (cf. cannulation and cardiac puncture). Here, a general set of recommendations are provided for optimizing the blood sampling protocol that reflects best practices in animal welfare and sample integrity. This includes selecting appropriate use of anaesthetics for blood sampling as well as restraint techniques for situations where sedation is not used. In addition, ideal sampling environments where the fish can freely ventilate and strategies for minimizing handling time are discussed. This study summarizes the techniques used for extracting blood from the caudal vasculature in live fishes, highlighting the phlebotomy itself, the timing of sampling events and acceptable blood sample volumes. This study further discuss considerations for selecting appropriate physiological metrics when sampling in the caudal region and the potential benefits that this technique provides with respect to long-term biological assessments. Although general guidelines for blood sampling are provided here, it should be recognized that contextual considerations (e.g., taxonomic diversity, legal matters, environmental constraints) may influence the approach to blood sampling. Overall, it can be concluded that when done properly, blood sampling live fishes through the caudal vasculature is quick, efficient and minimally invasive, thus promoting conditions where live release of focal animals is possible.

“…Electroimmobilization is an umbrella term recommended by Reid et al. () to cover electrosedation, electroanesthesia, electrotetany, and electrostunning, all forms of reversible sleep‐like states. The concept is simple: subject a fish to a low level of electric current sufficient to cause immobility and loss of sensory perception.…”

Development of Electrofishing for Fisheries Management

Electrofishing, broadly defined as the use of electricity to capture or control fish, was envisioned in an 1863 British patent application by Isham Baggs. Not until the 1920s, when large, stationary generators were available, did electrofishing applications (i.e., fish barriers) begin. After World War II, applications of electrofishing for fisheries management accelerated in diversity and portability. As the American Fisheries Society celebrates 150 years of dedication to aquatic resource conservation, our aim is to document the development of electrofishing for fisheries management in North America during the same period. Major management objectives comprise the topics in our article. While electrofishing has become a staple in fisheries management for conducting a wide range of applications such as population assessment and eradication of nuisance species, and how electrofishing use and equipment has evolved, particularly in response to human safety and fish welfare.
