Marine soundscapes provide the opportunity to non-invasively learn about, monitor, and conserve ecosystems. Some fishes produce sound in chorus, often association with mating, there is much about fish choruses species producing them. Manually analyzing years of acoustic data increasingly unfeasible, especially challenging as multiple can co-occur time frequency overlap vessel noise other transient sounds. This study proposes an unsupervised automated method, called SoundScape Learning (SSL), separate chorus from soundscape using integrated technique that makes use randomized robust principal component analysis (RRPCA), clustering, a neural network. SSL was applied 14 recording locations off southern central California able detect single interest 5.3 yrs acoustically diverse soundscapes. Through application SSL, found be nocturnal, increased intensity at sunset sunrise, seasonally present late Spring Fall. Further will improve understanding behavior, essential habitat, distribution, potential human climate change impacts, thus allow for protection vulnerable species.

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.

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.

ABSTRACT This review examines the progression of fish bioacoustics and ecoacoustics, with a focus on growing application Passive Acoustic Monitoring (PAM) as non‐invasive tool for assessing biodiversity. As environmental conservation goals intensify globally, particularly initiatives such Biodiversity Net Gain, need effective methods to monitor aquatic biodiversity has become increasingly critical. PAM provides scalable approach tracking species, community structures population dynamics across diverse habitats, addressing many limitations traditional monitoring techniques. By cataloguing species‐specific acoustic signatures, enables long‐term biodiversity, which is crucial in remote dynamic environments. Despite ongoing challenges – distinguishing species overlapping niches, managing large datasets ensuring precise classification sound types recent advancements artificial intelligence offer promising solutions. These technologies help balance trade‐off between analytical efficiency ecological biological significance necessary management conservation. presents an overview thematic structure temporal evolution field ecoacoustics discusses future directions support sustainable ecosystem

Acoustic and postural displays in a miniature and transparent teleost fish,Danionella dracula

Journal of Experimental Biology, Год журнала: 2022, Номер 225(16)

Опубликована: Авг. 2, 2022

Acoustic behavior is widespread across vertebrates, including fishes. We report robust acoustic displays during aggressive interactions for a laboratory colony of Danionella dracula, miniature and transparent species teleost fish closely related to zebrafish (Danio rerio), which are hypothesized be sonic based on the presence hypertrophied muscle associated with male swim bladder. Males produce bursts pulsatile sounds distinct postural display - extension lower jaw, morphological trait not present in other but courtship interactions. Females show no evidence sound production or jaw such contexts. Novel pairs size-matched -mismatched males were combined resident-intruder assays where could linked individuals. In both dyad contexts, resident produced significantly more pulses than intruders. During heightened activity, majority highest producers also showed increased extension. Residents extended their intruders Larger size-mismatched dyads extensions compared smaller counterparts, increasing absolute body size. These studies establish D. dracula as that modulates putatively residency size, providing foundation further investigating role multimodal new model clade neurogenomic neuroimaging aggression, social

Опубликована: Ноя. 1, 2023

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.

Journal of Fish Biology, Год журнала: 2024, Номер 104(5), С. 1579 - 1586

Опубликована: Фев. 28, 2024

Abstract The ability to detect and respond the presence of predation risk is under intense selection, especially for small‐bodied fishes. Damselfishes (Pomacentridae) use auditory vocalizations during inter‐ intrasexual interactions, but it not known if they can in context predator–prey interactions. Here, we test yellowtail damselfish, Chrysiptera parasema , learn associate territorial vocalization heterospecific humbug damselfish Dascyllus aruanus with risk. In conditioning trials were presented call while either blank water (control treatment) or chemical alarm cue derived from damaged skin conspecific was introduced. trials, fish exposed exhibited increased activity spent more time column relative that received control treatment. After a single trial, conditioned again damselfish. Fish + showed had been These data indicate associative learning an stimulus species regularly uses signalling other contexts. Recordings failed any acoustic calls produced by response perception Thus, although stimuli, found no evidence produce call.
