“…Monitoring a newly-established source population of round goby (Neogobius melanostomus) within the Rideau Canal in Ontario, Canada, Bergman et al (2022) were able to track the invasion front of this species which is normally native to the Black and Caspian Seas.…”

“…Dispersal amongst a quarter of the tagged individuals was established via receivers situated within canal locks which were hypothesised to enhance passage (Bergman et al, 2022). The scale of the challenge facing marine invasive control has been demonstrated through a study on lionfish (Pterois volitans) in the western Atlantic, showing an eight-fold variation in individual home range estimates (~48000 -379000 m 2 ) and ~40% of individuals travelling >1 km from the tagging site towards deeper habitat (Green et al, 2021).…”

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.

“…Biological invasions pose a major threat to native biodiversity and ecosystem health [1], as they have been shown to lead to the decline or extirpation of native species [2], have deleterious effects on ecosystem functions, and affect the global environment [3][4][5]. The four stages of biological invasions include introduction, establishment, spread, and impact; the eradication of invasive species is often considered a futile endeavor once the establishment stage is reached [6]. Human activities are responsible for the introduction of many marine invasive species, especially through ballast water [7,8]; however, ocean and coastal currents can promote the spread of invasive species over small areas and, thus, increase the complexity of the dynamics of invasions [9].…”

Mytella strigata (Hanley, 1843) is an invasive mussel species that has rapidly spread in China in recent years. Here, we tested the utility of three mitochondrial gene fragments, COI, 12S, and 16S, and two nuclear gene fragments, D1 28S and 18S-ITS1, for characterizing the levels of genetic diversity among and within populations using 191 M. strigata specimens collected in China to aid ongoing efforts to identify the origin of the invasion as well as molecular genetic studies. M. strigata exhibited two sex-associated haplogroups according to the COI and 12S sequences. The ratio of female-lineage to male-lineage COI and 12S sequences was 149:22 and 72:7, and the genetic distances between haplogroups were 6.56 and 9.17, respectively. Only one haplotype was detected among the 18S-ITS1 sequences (413 bp), and three haplotypes were detected among the D1 28S sequences (296 bp). The haplotype diversity of both the female-lineage COI and 12S sequences was greater than 0.5, and the nucleotide diversity of the 12S, 16S, D1 28S, and 18S-ITS1 sequences was less than 0.005 in all six populations in China. Our findings indicated that COI is the most useful gene fragment for genetic diversity studies of M. strigata populations; D1 28S and 18S-ITS1 sequences would be useful for species identification because of their low intraspecific diversity. Our genetic analysis of the COI sequences revealed Colombia as the most likely origin of M. strigata in China and showed that the invasive populations in China have recently experienced or are currently experiencing a population bottleneck.
