Aquatic insects are a major indicator used to assess ecological condition in freshwater environments. However, current methods collect and identify aquatic require advanced taxonomic expertise rely on invasive techniques that lack spatio-temporal replication. Passive acoustic monitoring (PAM) is emerging as non-invasive complementary sampling method allowing broad coverage. The application of PAM ecosystems has already proved useful, revealing unexpected diversity produced by fishes, amphibians, submerged plants, insects. the identity species producing sounds remains largely unknown. Among them, appear be contributor soundscapes. Here, we estimate potential number soniferous worldwide using data from Global Biodiversity Information Facility. We found four insect orders produce totalling over 7000 species. This probably underestimated owing poor knowledge bioacoustics. then value sound evaluate find they might useful despite having similar responses pristine degraded environments some cases. Both expert automated identifications will necessary build international reference libraries conduct bioassessment freshwaters. article part theme issue ‘Towards toolkit for global biodiversity monitoring’.

This paper outlines my research path over three decades while providing a review on the role of fish sounds in mate choice and reproduction. It also intends to provide advice young scientists point toward future avenues this field research. An overview studies different model species shows that male mating acoustic signals can inform females competitors about their size (dominant frequency, amplitude, sound pulse rate modulation), body condition (calling activity rate), readiness rate, number pulses sound). At least with parental care, such as toadfishes, gobies, pomacentrids, calling seems be main driver reproductive success. Playback experiments ran restricted consistently revealed prefer vocal silent males select for higher rates. personal synthesis concludes suggestion increase knowledge signals, especially considering emerging use monitor aquatic environments due increasing threats, like noise pollution.

The biological soundscape of temperate reefs in the Wadden sea

Scientific Reports, Год журнала: 2025, Номер 15(1)

Monitoring coastal marine habitats presents many challenges. Often, using multiple approaches to capture different aspects of ecosystems can strengthen the information gained regarding habitat status. The use passive acoustics document, describe, and monitor through soundscapes one such complementary technique. Marine have not yet been described for Wadden Sea; an ecosystem where reef experienced major changes over time due various human-mediated impacts. Recordings at a subtidal shellfish neighbouring sandflat six 2-week periods 14 month period in 2021 2022 provide first catalogue biotic acoustic signatures this ecosystem. Furthermore, recordings from two natural sites were compared recently deployed artificial sites, showing similar patterns greater diversity reefs nearby sandflats. These results demonstrate that fine-scale differences exist across within small geographic scales. This study provides foundations further quantitative research PAM soundscape dynamics Sea understanding role sound changing ecosystems.

Through sharing characteristics of chorus activity, especially in regions that are particularly data deficient, we can aim at a broader, global understanding fish chorusing and consequently important spatiotemporal changes habitat use by schooling fish. Here, identify seasonal activity using passive acoustic monitoring, the central Red Sea mesophotic adjacent shallow coral reef zones. For this study, recorders were placed zone (70–80 m), sites (10 over 2 weeks during summer winter seasons. A total eleven choruses identified catalogued according to timing, location frequency sound pressure levels. The presence both deep is indicative critical for foraging, courtship, spawning, and/or migratory activity. All but two found originate or near sites. Four unique (n=3 1 respectively) most prevalent soundscapes.

Acoustic fish community in a biogeographic transition zone of the Northeast Atlantic

ICES Journal of Marine Science, Год журнала: 2025, Номер 82(3)

Опубликована: Март 1, 2025

Abstract Fish sounds are a significant component of marine soundscapes. Recently, passive acoustic monitoring (PAM) arose as promising tool for ecological monitoring, but good characterization fish communities is still needed. This study the first to characterize community at biogeographic transition zone in Northeast Atlantic. The research was conducted protected area (MPA) along Portuguese mainland coast. Based on literature review, we identified 29 (19.3%) sound-producing species present this MPA, while 70 (46.7%) were considered potentially soniferous. Using situ recordings detect potential sounds, found 33 putative that categorized using simple dichotomous classification. temporal and spectral features 13 most prevalent sound types characterized compared among them with available identify similarities. Finally, hydrophone coupled baited remote underwater video systems tested method sources. provides catalogue from coast, laying foundations survey coastal habitats PAM.

Elasmobranchs are an evolutionarily ancient group of cartilaginous fishes that can hear underwater sounds but not historically viewed as active sound producers. Three recent reports several species rays producing clicks in response to approaching divers have cast doubt on this long prevailing view and resulted calls for more research into production elasmobranchs. This study shows the rig, Mustelus lenticulatus , produces (mean SPL rms = 156.3 dB re. 1 μPa ± 0.9 s.e.m. at approx. 30 cm) when handled underwater, representing first documented case deliberate by a shark. Clicks were broadband bandwidth 23 kHz 0.1 s.e.m.), with peak energies between 2.4 18.5 frequency 9.6 0.3 mean duration 48.42 ms 2.9 contained considerably less energy frequencies below kHz, which overlap hearing range rig. We propose forceful snapping flattened teeth may be mechanism based plated tooth morphology acoustic characteristics these clicks. Further behavioural studies needed test whether incidental handling or natural significance.

Managing Aquaculture Noise: Impacts on Fish Hearing, Welfare, and Mitigation Strategies

Reviews in Aquaculture, Год журнала: 2025, Номер 17(3)

Опубликована: Апрель 14, 2025

ABSTRACT As intensive aquaculture continues to develop, substantial investments have been made in equipment sustain high‐density farming. However, this has resulted elevated noise levels within these environments, particularly below 2000 Hz, matching the hearing range of most cultured fish species. Fish under conditions may experience loss and physiological stress, which can negatively affect their growth, foraging efficiency, reproductive success, increase susceptibility diseases. These adverse effects compromise welfare fish, potentially decreasing production quality increasing mortality rates. Despite notable effects, understanding management systems lag behind other environmental parameters terms recognition control. In review, we cover fundamentals auditory systems, key species, common sources prevalent current systems. Additionally, examine recent discoveries on anthropogenic hearing, responses, behavior. Finally, provide strategies for monitoring industry, while also highlighting open questions future research. Our goal is assist researchers practitioners comprehending underwater its providing a valuable resource promoting healthy sustainable development aquaculture.
