“…They recorded numerous biological sounds: in addition to several sounds produced by certain cetaceans and dolphins, they recorded at least 12 unique unidentified sounds that were believed to be produced by fish or cetaceans. Carrico et al (2019Carrico et al ( , 2020 recorded biological sounds using Ecological Acoustic Recorders bottom-moored 5-10 m from the Condor seamount at an approximate depth of 190 m and on the seafloor at a depth of 36 m in Princess Alice Bank. Although the Azores hosted a wealth of fish species, only 20 species from 14 families had been reported, and at least 79 species from 24 families were potential sound producers.…”

We report herein an underwater biological chorus coming from the margin of the New Jersey Atlantic continental shelf that we tentatively attribute to a species of fish. The chorus occurred every night for over a month during the Shallow Water 2006 experiment and covers the frequency band 150–4,800 Hz, with maximum intensity in the band from 1450 to 2,000 Hz. Remarkable intensity peaks occurred at 500, 725, 960, 1,215, 1,465, 1,700, and 1,920 Hz, rising to as much as 20 dB above the background noise without the chorus. The chorus begins at sunset and reaches its maximum intensity within an hour, following which it weakens slightly and then gradually climbs again to a peak before sunrise, at which point it quickly weakens and disappears. Its frequency-domain characteristics and the nocturnal timing are reminiscent of sound produced by underwater animals. The intensity of the chorus weakens along the across-shelf path going shoreward, which indicates that the chorus originates from the margin of the continental shelf rather than from the coastal zone, as is generally considered. The chorus contains a single type of acoustic signal that takes the form of double-pulse bursts that last about 8.7 ms, with each pulse containing several acoustic cycles. The time interval between successive bursts varies from 1.5 to 1.9 s. Signals containing a number of bursts vary in length from tens to hundreds of seconds. Although it is impossible to determine the fish species responsible for the chorus, its characteristics, including its low frequency and intensity, its single type of short-duration sound signal, and its multiple peaks in the frequency domain, are all consistent with the general characteristics of fish sounds.

“…In particular, the combination of hydrophone‐integrated gliders (mobile acoustic monitoring, MAM) with static acoustic monitoring (SAM), joined with advanced signal processing tools, could provide a holistic understanding of the biology of deep‐sea fish species and of ecosystem dynamics over large spatial and temporal scales. SAM can provide long‐term acoustic data which inform on diel and seasonal patterns of activity (Carriço et al, in press), while MAM can inform on large‐scale, stratigraphic distribution of vocal populations (Bolgan et al., 2020). The use of video cameras with integrated sound recorders is required to identify fish species, to link acoustic diversity to specific diversity, to assess the commercial interest of the identified species and to estimate their relative abundance (Mouy, Rountree, Juanes, & Dosso, 2018).…”

“…A small number of passive acoustic studies have monitored fish vocal activities in the deep sea (Bolgan et al., 2020; Carriço, Silva, Menezes, Fonseca, & Amorim, 2019; Carriço et al, in press; Cato, 1978; Kelly, Kewley, & Burgess, 1985; Mann & Jarvis, 2004; McCauley & Cato, 2016; Rountree et al., 2012; Wall, Simard, Lembke, & Mann, 2013; Wall et al., 2014; Wall et al., 2017; see Table 1). These pioneering studies provide valuable lessons for maximizing further attempts.…”

“…Therefore, a fundamental requirement for a successful PAM of deep‐sea fish is a type of deployment which minimizes self‐noise (Rountree et al., 2020; Rountree & Juanes, 2010; Wall et al., 2014). This is the case of static acoustic monitoring (SAM; Bolgan et al., 2020; Carriço et al., 2019; Carriço et al, in press; Cato, 1978; McCauley & Cato, 2016; Wall et al., 2013) and of gliders (Bolgan et al., 2020; Wall et al., 2013, 2017). SAM is static and silent devices (i.e., hydrophone arrays deployed on the sea bottom) already used to record deep‐sea fish sounds, for example in the Bahamas (Mann & Jarvis, 2004), in the West Florida Shelf (USA; Wall et al., 2013), in the Perth canyon (AUS) (McCauley & Cato, 2016) and in Azores seamounts (Carriço et al., 2019; Carriço et al, in press).…”

In this latter environment, in particular, three years of acoustic data were analysed for diversity and abundance of fish sounds; these reflected fishing data obtained from deep‐water longline surveys, strongly supporting SAM as an effective, non‐invasive tool for informing on deep‐sea fish populations dynamics over long time scales (Carriço et al, in press).…”

Sound production represents an integral part of social communication in many teleost fish; however, few studies have investigated the structure, organization and variability of fish sounds at the community level. Fish acoustic community structure was recorded simultaneously in three sites located along the Mediterranean basin within the endemic habitat of Posidonia oceanica seagrass beds. Acoustic diversity and species‐specific sound features were expected to differ between locations. We predicted that, in communities characterized by higher acoustic richness, fish species would specialize in their use of acoustic resources (i.e. realized acoustic niche compression), while the overall allocation of resources within the community signal space would expand. The fish acoustic communities inhabiting Posidonia beds were characterized by the same main contributors (the /Kwa/, Ophidion rochei and Sciaena umbra sound types). However, their relative occurrence, abundances and use of acoustic resources were site‐specific. Acoustic diversity differed between geographic locations. The range of spectral and temporal resources exploited by the fish acoustic community was wider in sites where acoustic richness was at its highest score. Ophidion rochei was highly specialized in its use of temporal resources where acoustic richness was higher, whilst S. umbra appeared less efficient in specializing the use of spectral and temporal resources. By showing that the same species can exploit different acoustic resources between locations, this study supports the concept of Acoustic Niche plasticity (i.e. plasticity of acoustic resources allocation within a species). The results suggest that the degree of acoustic niche plasticity might be determined by the species‐specific degree of sound‐producing system plasticity. In turn, different degrees of acoustic niche plasticity might determine different species‐specific levels of acoustic adaptability to changing biotic or environmental conditions.
