“…For example, PAM has allowed the detection of an invasive fish species (i.e. Cynoscion regalis ) in European waters, whose presence was only recently reported based on anglers’ records (Amorim et al, 2023). Increasing the knowledge of fish communicative sounds on the one hand, and including PAM in the monitoring tool‐kit of ecologists, scientists and managers on the other, will ultimately contribute to better information on a wider taxonomic spectrum.…”

Knowledge of the ecology, spatial distribution and conservation status of fish populations is achieved by fishery‐dependent techniques, and by more recently developed non‐invasive fishery‐independent techniques. Passive acoustic monitoring (PAM) is a fishery‐independent method that provides remote sensing of soniferous species, populations, communities and ecosystems by recording soundscapes and their components. A case study is presented to demonstrate how PAM can contribute to a dynamic understanding of fish distribution, ecological preferences and conservation status. This case study refers to the cusk‐eel Ophidion rochei (Ophidiiformes), a nocturnal, behaviourally cryptic, soniferous fish species, described as uncommon and rare in the scientific literature, and listed as Data Deficient in the IUCN Red List. A systematized literature review was carried out using Ophidion+rochei as the search term, and by grouping records into two main categories: (i) traditional techniques (including all fishery‐dependent techniques and underwater visual census); and (ii) PAM. This review highlights how PAM has provided new sightings of O. rochei at a rate three times higher than all other monitoring techniques combined. In contrast with the knowledge achieved to date by fishery‐dependent techniques, the reported acoustic mass phenomena indicate that this species can be very abundant. Ophidion rochei was found to inhabit a wide range of depths and ecosystems, at least throughout the Mediterranean basin. This paper supports the urgency and the importance of relying on the integration of different fishery‐independent techniques for multidisciplinary monitoring, in line with the Goal 14 requirements of the UN Decade of Ocean Science for Sustainable Development.

“…The 'Jackhammer' sounds fit within the known vocalization frequency range of fish (<3 kHz) and is a repetitive set of impulse sounds (Amorim, 2006;Carriço et al, 2019). They resemble sounds produced by fish species from the family Sciaenidae (Amorim et al, 2023) and occurrences of an invasive species of this family have been also documented for the North Sea (Morais et al, 2017). The short duration, high frequency 'Tick' sounds are similar to crustacean acoustic signals, which are known to span a large range of frequencies (Edmonds et al, 2016;Solé et al, 2023).…”

Biological invasions pose significant threats to biodiversity and ecosystem functioning. Removal of introduced species is most successful when detected early. We evaluate the effectiveness of passive acoustics combined with automated recognition in detecting the invasive American bullfrog (Lithobates catesbeianus). We applied this technique to two real-world monitoring programs aimed at determining the optimal time of day for monitoring the species in Europe, for which we recorded the species in Belgium and Italy; and for evaluating the effectiveness of BirdNET (a free and user-friendly automated recognizer) in analyzing a large dataset collected in Spain. BirdNET was highly effective in automatically detecting the bullfrog presence, with a detection rate (compared to visual inspection of sonograms) of 89.5% using default settings (85 of 95 recordings with known presence), and 95.8% with user-specific settings (91 of 95 recordings detected). The system showed remarkable precision, correctly identifying 99.7% (612 out of 614) of the verified predictions, and with only one mislabelled recording (predicted to be present when it was absent). The species’ vocal activity in Belgium and Italy was higher during the night compared to crepuscular periods. Recording analyses and output verification of the dataset collected in Spain was carried out in 3.8% of the recorded time, and resulted in significantly reduced effort compared to visual inspection. Our study highlights the effectiveness of this technique for remotely surveying the American bullfrog, making it a significantly potential tool for informing management decisions, particularly for the early detection of the species’ arrival in new areas.
