“…No such correlations to temperature are described at other locations. Instead, Monczak, Berry, Kehrer, and Montie ()and Ricci, Bohnenstiehl, Eggleston, Kellogg, and Lyon () mention seasonal, lunar and daily calling rhythms as well as differences between recording locations (Montie et al., ) (Table ). Amorim, Vasconcellos, Marques, and Almada () observe seasonal patterns of emission of different sound types (croaks, grunt trains, boatwhistles) in Lusitanian toadfish ( Halobatrachus didactylus , Batrachoididae); these patterns are significantly correlated to the temperature in the Tagus estuary, Portugal.…”

“…While many studies revealed a relationship between calling activity/sound characteristics and temperature, several studies failed to report such a relationship (cod—Brawn, ; oyster toadfish—Monczak et al., ; Ricci et al., ; Lusitanian toadfish—Amorim et al., ). A drop in the calling activity of the Lusitanian toadfish in late July despite high temperatures (Figure b) most likely reflects seasonal androgen changes according to the authors (the effects of sex steroids on fish acoustic communication are reviewed in Maruska & Sisneros, ).…”

“…Sound recordings were carried out in several species of sciaenids in the field, and they typically yield a positive correlation to temperature (Monczak et al, 2017;Montie et al, 2015) along with dependencies on water depth, seasonal, daily and lunar rhythm. Rice et al (2016) found that chorusing occurs at night and at temperatures below 20°C (2016).…”

Temperature affects peripheral and central mechanisms of signal production and detection in ectothermic animals. This study reviews for the first time the effects of temperature on acoustic communication in fishes and analyses whether changes in sound properties are coupled to changes in auditory sensitivities. Effects of temperature on sound production have been studied in approximately one dozen families of teleosts. Calling activity increased or was unaffected by temperature, in the latter case probably because seasonal, daily and lunar rhythms also influence mating behaviour and calling. Sound characteristics (pulse repetition rate, fundamental frequency) are positively correlated with temperature if pulses are directly based on sonic muscle contractions. In fishes possessing other sonic mechanisms, the dominant frequency of their pulsatile pectoral sounds may increase as well. Auditory sensitivities were mainly determined in otophysines, which possess enhanced hearing abilities. Studies revealed that hearing increased with temperature, in particular at higher frequencies. We know close to nothing about whether temperaturedependent changes in sound characteristics are coupled to changes in auditory sensitivity or mate choice. Female midshipman toadfish appear to choose males based on call frequency, which varies with temperature. Future studies need to address several topics: (i) temperature effects on sound production have to be separated from other sources of variation; (ii) effects on hearing need to be studied in many more taxa; (iii) potential negative effects of global warming on acoustic communication (because of temperature coupling) need to be investigated because fish constitute a major source of protein for humans.

“…The use of acoustic signalling by burbot presents the possibility of using passive acoustic monitoring to evaluate the location of spawning habitat and the timing of spawning activity. Passive acoustic monitoring has proven successful for mapping the location and timing of the spawning aggregations of sciaenid fishes, such as red drum ( Sciaenops ocellatus ) and spotted seatrout ( Cynoscion nebulosus ; Lowerre‐Barbieri et al., ; Luczkovich & Sprague, ; Monczak, Berry, Kehrer, & Montie, ; Walters, Lowerre‐Barbieri, Bickford, & Mann, ), as well as gadid fishes, such as Atlantic cod (Nordeide & Kjellsby, ) and haddock (Casaretto, Picciulin, Olsen, & Hawkins, ). The development of a reliable protocol for using passive acoustic monitoring to locate burbot spawning aggregations would provide a useful non‐invasive tool to assess the success of reintroduction efforts as well as surveying the spatial distribution and temporal use patterns of burbot spawning habitat.…”

Looking for love under the ice: Using passive acoustics to detect burbot (Lota lota: Gadidae) spawning activity

Burbot (Lota lota: Gadidae) is a difficult species to manage effectively due to its preference for deep‐water habitats and under‐ice spawning behaviour, resulting in a poor understanding of its reproductive activity. However, the use of acoustic signalling by burbot as part of their mating system has recently been described and this behaviour may provide a means of investigating questions regarding the spatial and temporal distribution of spawning aggregations using passive acoustic monitoring. We used audio and video recording to confirm that burbot vocalise and that these vocalisations can be detected under field conditions as well as to characterise the relationship between burbot acoustic signalling and spawning behaviour. We also evaluated the feasibility of locating and monitoring burbot spawning aggregations in real time using passive acoustics. Burbot vocalisations were difficult to identify with only about 6% of the recordings containing calls being successfully identified as such in the field. Burbot vocalised more often between sundown and sunrise than during daylight hours. Calls recorded at night tended to be lower frequency, longer duration, and have lower bandwidth than those made during the day. Burbot vocalisations could not be recorded in conjunction with video recordings of spawning activity, indicating that burbot may not call during active spawning, but may use acoustic communication to signal the onset of reproductive readiness and to form pre‐spawning aggregations. While burbot calls were readily identifiable, observers had a difficult time identifying burbot calls in real time under field conditions. Passive acoustic monitoring demonstrates considerable potential as a management tool to locate burbot spawning grounds and identify periods of activity, but may not be an appropriate technique for monitoring spawning activity in real time.

The brown meagre (Sciaena umbra) is a demersal sciaenid fish recognized as indicative of good environmental quality and is defined as an umbrella species for the ecological community of rocky coastal habitats. Sciaena umbra is classified as a Vulnerable fish species by the International Union for Conservation of Nature (IUCN) and knowledge on the distribution of its spawning habitats is essential for its conservation. Passive acoustic monitoring (PAM) is a suitable tool to monitor S. umbra distribution because of the high consistency, over space and time, of the communication sounds that this species emits during the reproductive period, with irregular or regular rhythms, or with calls merging into a chorus. During the summer of 2019, the presence of this species was investigated acoustically at 40 listening points distributed along the tidal inlets that connect the Venice lagoon with the open sea. Longer sounds, comprising a higher number of faster repeated pulses, were found during the chorus and were used as a proxy of spawning activity; similar sound features have been recorded in different captive Sciaenids during spawning. The three inlets were classified as more or less suitable for spawning on the basis of the vocal rhythms identified, demonstrating a clear preference along a north–south gradient and indicating higher spawning activity in the internal‐facing areas of the inlets, compared with the seaward‐facing areas. The chorus occurred in localized areas consistently throughout the breeding season, suggesting that spawning is concentrated in preferred areas. For the first time a relationship between the sound features and vocal rhythms of fish has been highlighted by an in situ study. This validates the use of the chorus as a reliable natural indicator of S. umbra breeding sites, and in turn suggests a potential non‐invasive approach based on PAM for mapping the key reproductive areas of this vulnerable species in the Mediterranean Sea.
