“…Even with great investments in telemetry science, there is still a lack of documentation and assessment of the conservation impact of telemetry research (Jeffers andGodley 2016, Mcgowan et al 2016). Hesitation and delay in applying telemetry-derived data to fisheries management have also been reported for reasons such as uncertainties associated with telemetry studies, limitations of the technology, unknown effects on tagged animals, distrust of telemetry (reliability and credibility issues), mismatches between management needs and design of telemetry studies (e.g., compatibility, representativeness, timeliness), or lack of awareness and access to new findings , Young et al 2013, 2018, Crossin et al 2017Nguyen et al, 2018a,b). It has also been suggested that publications are too focused on research results rather than on conservation and management implications, and that the recommendations put forth lack context and are not readily useable by decision makers (Roux et al 2006).…”

“…Research networks offer an opportunity to expand this research, given that they often include both scientists and practitioners. For example, the Great Lakes Fishery Commission and its associated Great Lakes Acoustic Telemetry Observation System (network of telemetry researchers) make up a community of both science and practice (Krueger et al 2018). Evaluating the various cases that have derived from Great Lakes fisheries research using telemetry could be a viable method to get to a truer measure of "successful" knowledge outcomes.…”

Aquatic telemetry technology generates new knowledge about the underwater world that can inform decision‐making processes and thus can improve conservation and natural resource management. Still, there is lack of evidence on how telemetry‐derived knowledge can or has informed management, and what factors facilitate or deter its use. We present one of the first quantitative studies related to the science‐action gap and evaluate factors that influence the uptake of fish telemetry findings into policies and practices, as well as social acceptance of these findings. We globally surveyed 212 fish telemetry researchers regarding the knowledge uptake of an applied fish telemetry research project of their choice. Respondents’ personal and professional attributes, as well as the attributes of their chosen projects, were analyzed using machine learning algorithms to identify important factors that influenced the uptake (i.e., use, trust, and/or acceptance) of their findings. Researchers with extensive collaborations and who spent more time engaging in public outreach experienced greater uptake of their findings. Respondents with greater telemetry experience and commitment (e.g., more telemetry publications, higher proportion of research on fish telemetry) tended to achieve more social acceptance of their findings. Projects led by researchers who were highly involved and familiar with the fisheries management processes, and those where greater effort was devoted to research dissemination, also tended to experience greater uptake. Last, the levels of complexity and controversy of the issue addressed by the research project had a positive influence on the uptake of findings. The empirical results of this study support recent messages in the science practitioner literature for greater collaboration, knowledge co‐production with partners, and public engagement to enable the transfer of knowledge and the use of evidence in decision‐making and policies. Scientific organizations should consider shifting reward incentives to promote engagement and collaboration with non‐scientific actors, and perhaps even rethinking hiring practices to consider personal and professional characteristics or attitudes such as altruism and networking skills given the influence of these factors in our model. Last, networks composed of both research and practice potentially have a key role in brokering and facilitating knowledge exchange and actions.

“…The design of a network is a challenging task primarily because the deployment and maintenance of expansive acoustic receiver networks may be beyond the capabilities of most single organizations, and thus requires interagency coordination. Consortiums and organizations, such as the Great Lakes Acoustic Telemetry Observation System (GLATOS; http://glatos.glos.us/, Krueger et al., ), Integrated Marine Observing System (IMOS; http://imos.org.au/home/) and the Ocean Tracking Network (OTN; Cooke et al., ), are becoming increasingly important for the success of acoustic telemetry studies, but this enterprise requires compromise in the sampling design to manage financial resources and achieve a network that will function for multiple objectives and species. Studies initiated after a network is established will be forced to consider whether the existing array addresses the objective(s) or whether augmentation of the network would be necessary.…”

Evaluation of acoustic telemetry grids for determining aquatic animal movement and survival

Acoustic telemetry studies have frequently prioritized linear configurations of hydrophone receivers, such as perpendicular from shorelines or across rivers, to detect the presence of tagged aquatic animals. This approach introduces unknown bias when receivers are stationed for convenience at geographic bottlenecks (e.g. at the mouth of an embayment or between islands) as opposed to deployments following a statistical sampling design. We evaluated two‐dimensional acoustic receiver arrays (grids: receivers spread uniformly across space) as an alternative approach to provide estimates of survival, movement and habitat use. Performance of variably spaced receiver grids (5–25 km spacing) was evaluated by simulating (1) animal tracks as correlated random walks (speed: 0.1–0.9 m/s; turning angle SD: 5–30°); (2) variable tag transmission intervals along each track (nominal delay: 15–300 s); and (3) probability of detection of each transmission based on logistic detection range curves (mid‐point: 200–1,500 m). From simulations, we quantified (i) time between successive detections on any receiver (detection time), (ii) time between successive detections on different receivers (transit time), and (iii) distance between successive detections on different receivers (transit distance). In the most restrictive detection range scenario (200 m), the 95th percentile of transit time was 3.2 days at 5 km, 5.7 days at 7 km and 15.2 days at 25 km grid spacing; for the 1,500 m detection range scenario, it was 0.1 days at 5 km, 0.5 days at 7 km and 10.8 days at 25 km. These values represented upper bounds on the expected maximum time that an animal could go undetected. Comparison of the simulations with pilot studies on three fishes (walleye Sander vitreus, common carp Cyprinus carpio and channel catfish Ictalurus punctatus) from two independent large lake ecosystems (lakes Erie and Winnipeg) revealed shorter detection and transit times than what simulations predicted. By spreading effort uniformly across space, grids can improve understanding of fish migration over the commonly employed receiver line approach, but at increased time cost for maintaining grids.

Understanding the spatial ecology of sturgeon (Acipenseridae) has proven to be a challenge due to the life history characteristics of these fish, especially their long life span, intermittent spawning, and long‐distance migrations. Within the Huron‐Erie Corridor (HEC) of the Laurentian Great Lakes, habitat use of 247 lake sturgeon (Acipenser fulvescens) was monitored over a three‐year period (2015–2017) with acoustic transmitters. Extensive spatial coverage of receivers throughout the St. Clair River, Lake St. Clair, and Detroit River between Lake Huron and Lake Erie (~150 km) allowed for continuous monitoring of the movements of acoustic‐tagged individuals. Sequence analysis of individual detection histories was used to describe lake sturgeon habitat use and to determine (1) whether distinct habitat‐use patterns occurred within the HEC; (2) whether the range of habitats occupied varied across seasons among sturgeon grouped by common patterns; and (3) whether variation identified was related to tagging sites in the two rivers or sex. Lake sturgeon were active throughout the HEC, but five distinct habitat‐use patterns were identified. River residents were not broadly distributed across entire rivers, but rather associated with particular segments (middle Detroit River, St. Clair River delta). Variations in habitat‐use sequences were in part related to three river tagging sites, but not sex, and did not produce groups with sequences that reflected all five habitat‐use patterns derived from cluster analysis. Lake sturgeon distribution was reduced to fewer habitat segments during winter and expanded to the maximum extent during the spring and summer. Conservation planning that incorporates behavioral diversity of habitat use is relatively rare due to a lack of observations on movements of individuals at biologically relevant spatial and temporal scales, but using telemetry and sequence analysis methods may promote the success of conservation and restoration efforts.
