“…However, the prevalence and spatial-temporal scale of residency remain partially unclear, given the number of tagged individuals and limited receiver coverage. In the gaps between detections, individuals could have moved into other parts of the MPA or beyond MPA boundaries (Williamson et al, 2021). In some settings, alternative array designs, such as paired gated arrays, provide additional (directional) information that can help to distinguish these possibilities (Heupel, Semmens & Hobday, 2006).…”

Marine Protected Areas (MPAs) are widely used in marine management, but for mobile species understanding the spatio‐temporal scale of management measures that is required to deliver conservation benefits depends on a detailed knowledge of species’ movements that is often lacking. This is especially the case for species of skate (Rajidae) for which relatively few movement studies have been conducted. In Scotland, the Loch Sunart to the Sound of Jura MPA covering 741 km2 has been designated for the conservation of the Critically Endangered flapper skate (Dipturus intermedius), but fine‐scale movements within this area remain poorly understood. A passive acoustic telemetry study which coupled acoustic tagging of 42 individuals and a static array of 58 receivers was conducted from March 2016 to June 2017. Using acoustic detection time series, angler capture–recapture data and depth time series from archival tags, fine‐scale movements of individuals were investigated. Overall, 33 of the 42 tagged individuals were detected. Residency, site fidelity and transiency were documented. Residency around receivers, lasting from 3 to more than 12 months, was documented in 16 acoustically detected individuals (48%) and all life‐history categories, but was most noticeable among females. Acoustic detections were associated with depth, salinity and season, but there was no evidence that individuals formed close‐knit groups in the areas in which they were detected. Taken together with historical occurrence records of flapper skate, the prevalence and scale of residency documented here suggest that the MPA is sufficiently large to benefit a notable percentage (38 [24–52]%) of skate found in the study area over monthly and seasonal timescales. This result strengthens the case for the use of MPAs to support the conservation of flapper skate and other skate species that display similar movement patterns in areas of high local abundance.

“…Anguillid eels have sex-biased differences in migration strategies, causing differences in movement patterns in lotic systems (Oliveira 1999), as well as both habitat and latitude sex-biased distributions (Magurran and Garcia 2000; Oliveira et al 2001;Maes and Volckaert 2007;Hagihara et al 2018;Wakiya et al 2019). Sex differences in movement patterns are seen across many marine and freshwater species (Bansemer and Bennett 2011; Nifong et al 2015;Widmann et al 2015;Gutowsky et al 2016;Williamson et al 2021). If feasible, sex should be integrated in investigations into anguillid eel movement because, given the differences migration strategies between sexes, there are likely to be important implications for conservation and management plans.…”

Anguillid eels are near globally distributed catadromous fishes with marine spawning areas and inshore and inland growth areas in both lotic (rivers, estuaries) and lentic (lakes, ponds, lagoons) water bodies. As predators, anguillid eels play an important ecological role in both marine and freshwater systems, and several species are harvested commercially for food. However, some of the more widely distributed species have undergone severe declines in recruitment and their population status is now of significant concern. Given the multiple and lengthy migrations undertaken by anguillid eels, understanding of the drivers of movement is fundamental for species conservation and management. Yet, despite the importance of lentic systems to their ecology, most studies on anguillid eel movement have been conducted in lotic systems. Given that key influences on eel migration in lotic water bodies, such as fluctuations in flow and water temperature, may be minimised in lentic environments, the transferability of findings between lotic and lentic systems cannot be assumed. A systematic map was constructed to synthesise current knowledge on the extrinsic and intrinsic drivers of anguillid eel movement in lentic systems. The current state of knowledge of the drivers of eel movement in lentic systems is presented and compared to the relatively well-understood drivers of movement in lotic systems. We also discuss current knowledge gaps and limitations, and identify key future research requirements to inform the management and conservation of anguillid eels in understudied lentic systems.

“…The application of network analyses to tease apart some of these processes is still in its relative infancy, particularly the utilisation of edge durations (time associated with movements from one receiver to another) to explore some of the mechanisms driving connectivity. These detection 'gaps' have proven useful for inferring different fish behaviours associated with 'restricted' movements and 'out-of-range' dispersal (Williamson et al, 2021). To date, network approaches have been successfully applied to AT data to show how reef-associated shark species connect different management zones in the Great Barrier Reef (Espinoza, Lédée, et al, 2015), and how movement strategies can influence species risk to illegal fishing inside marine protected areas (Jacoby et al, 2020).…”

What acoustic telemetry can and can’t tell us about fish biology

Acoustic telemetry (AT) has become ubiquitous in aquatic monitoring and fish biology, conservation and management. Since the early use of active ultrasonic tracking that required researchers to follow at a distance their species of interest, the field has diversified considerably with exciting advances in both hydrophone and transmitter technology. Once a highly specialised methodology however, AT is fast becoming a generalist tool for those wishing study or conserve fishes, leading to diversifying application by non-specialists. With this transition in mind, we evaluate exactly what AT has become useful for, discussing how the technological and analytical advances around AT can address important questions within fish biology. In doing so, we highlight the key ecological and applied research areas where AT continues to reveal crucial new insight, and in particular, when combined with complimentary research approaches. We aim to provide a comprehensive breakdown of the state of the art for the field of AT, discussing the ongoing challenges, where its strengths lie, and how future developments may revolutionise fisheries management, behavioural ecology and species protection. Through selected papers we illustrate specific applications across the broad spectrum of fish biology. By bringing together the recent and future developments in this field under categories designed to broadly capture many aspects of fish biology, we hope to offer a useful guide for the non-specialist practitioner as they attempt to navigate the dizzying array of considerations and ongoing developments within this diverse toolkit.
