“…Conversely, retention of up to 100% in Blue Catfish over 5 months has been observed (Gerber 2015). These confounding results suggest that unaffixed transmitters in the peritoneal cavity may be suitable for the study of catfish if proper pretagging preparation and preventative measures are taken during the tagging process (Gerber et al 2017(Gerber et al , 2019a. To reduce expulsion, researchers experimented with implanting transmitters in the peritoneal cavity similar to the unaffixed method but using wire or suture material to affix the transmitter to the pectoral or pelvic girdle (Lee 2009;Huck 2014;Hansen 2019).…”

Catfishes (Ictaluridae) are among North America’s most important ichthyofauna for human consumption and recreation. As such, research on Blue Catfish Ictalurus furcatus, Channel Catfish I. punctatus, and Flathead Catfish Pylodictis olivaris has been abundant in historic and contemporary literature. A common technique for studying catfish involves marking or tagging fish to understand behavior, sampling efficiency, and population dynamics. Marking and tagging methods used in these studies may be divided into eight primary types, including fin clips, strap tags, anchor tags, transbody tags, injectable tags, skin alterations, origin markers, and telemetry. Each of these methods is appropriate for specific objectives and characterized by varying retention rates and data resolution (i.e., batch or individual identification) that warrant consideration when designing projects. For example, fin clips may be most appropriate as a short‐term mark requiring batch identification (e.g., stocking evaluation), whereas telemetry might be most appropriate as a long‐term tag requiring individual identification (e.g., habitat selection). This review summarizes marking and tagging methods used for evaluation of Blue, Channel, and Flathead catfish and synthesizes results using examples from previously conducted catfish research. Further discussion is included on information gaps, emerging trends, and guidance for scientists planning and conducting studies that require marking of catfish.

“…Fish are widely used animal models in research and are a frequent subject of telemetry research; consequently, increasing attention is paid to the tagging protocols [33,65,66,97,316]. Evaluations and testing address all stages from capture to release [284] and even posttagging evaluation [41,97,300]. Evidence of nociceptory perception by fish suggests that caution must be devoted to these tagging procedures [38] that can impair their welfare and introduce bias in experiments when data reflect distressed, injured, or otherwise inauthentic movements.…”

A role for lakes in revealing the nature of animal movement using high dimensional telemetry systems

Movement ecology is increasingly relying on experimental approaches and hypothesis testing to reveal how, when, where, why, and which animals move. Movement of megafauna is inherently interesting but many of the fundamental questions of movement ecology can be efficiently tested in study systems with high degrees of control. Lakes can be seen as microcosms for studying ecological processes and the use of high-resolution positioning systems to triangulate exact coordinates of fish, along with sensors that relay information about depth, temperature, acceleration, predation, and more, can be used to answer some of movement ecology’s most pressing questions. We describe how key questions in animal movement have been approached and how experiments can be designed to gather information about movement processes to answer questions about the physiological, genetic, and environmental drivers of movement using lakes. We submit that whole lake telemetry studies have a key role to play not only in movement ecology but more broadly in biology as key scientific arenas for knowledge advancement. New hardware for tracking aquatic animals and statistical tools for understanding the processes underlying detection data will continue to advance the potential for revealing the paradigms that govern movement and biological phenomena not just within lakes but in other realms spanning lands and oceans.

“…This study accumulated data from fish over a few days to a few weeks and where it has been examined, tag expulsion is thought to occur over a longer period (i.e., 40 days; Lacroix et al 2004, Brunsdon et al 2019). In addition, to infer an ultimate fate to each tagged fish, we followed postulations used in other recent studies (for example, see Gerber et al 2017, Flávio et al 2020a, Klinard and Matley 2020, Villegas-Ríos et al 2020, Weinz et al 2020), with some modifications for the local study area, to infer nine categories of riverine migration outcomes from tag detection patterns (see Table 1 and A1 for more details). A Chi-squared test (Zar 2010) was used to determine if the of number of migration failures was spatially randomly distributed throughout the River Endrick by dividing the river into 1 km sections.…”

The process of smolting is a critical phase in the life-cycle of anadromous salmonids and it has been associated with substantial rates of mortality. Survival during freshwater and marine migration is known to have population level effects, thus an understanding of the patterns of mortality has the potential to yield important insights into population bottlenecks. Despite important advancements in tracking techniques, the specifics of mortality events in anadromous salmonids during their initial migration to sea remains somewhat elusive. Here, we develop a framework combining spatial and temporal detections of smolt riverine migration from two tracking techniques, which enable inferences to be made about mortality locations, causes, and rates. We embed this framework into a fine-scale behaviour study of migration and social structure. In this study, we demonstrate that during their initial riverine transitional phase, smolts were particularly vulnerable to predators. Specifically, avian predation appeared to be the main cause of mortality (42%), although piscine predation events were not trivial (14%). Our results suggested some direct and indirect tagging-induced mortality (e.g., through increased predation vulnerability), which highlights the importance of determining tagging mortality in a telemetry study to ensure adequate interpretation of migration success. There is evidence that predation induced selection on smolt morphology. Unsuccessful river salmon migrants with a phenotype comprising a shorter head and jaw and smaller eye had a higher probability of mortality in the later parts of riverine migration where avian and aquatic predation mortality dominated. In contrast, mortality earlier in river migration was independent of phenotype, most likely a result of tagging effects. Successfully river migrants were found to be interacting with each other, often in a pair or as a trio, indicating that a few individuals of Atlantic salmon and sea trout formed notable intra- and interspecific social associations. However, the heterogeneity of the social associations of successful migrants did not support the assumption that social network features attributed any clear specific benefits of reduced predation risk. Overall, by estimating migration loss and its variability, our study framework should help to guide management actions to mitigate the widespread population declines these species are currently facing.
