“…The month and lunar days of surveys were chosen based on a previous study by Sala et al (2003), who speculated that peak reproductive activity occurs during these periods. As spawning, courtship and sound production had not previously been observed in the species, 6 days Terminology and descriptions of behaviours associated with territorial patrols, aggression, courtship and spawning rushes followed those reported for other species of epinephelids with some speciesspecific variation (Donaldson, 1995;Erisman et al, 2007Erisman et al, , 2010aGilmore & Jones, 1992;Samoilys & Squire, 1994;Schärer et al, 2012aSchärer et al, , 2014Zabala et al, 1997). Behaviours included patrols, lateral standoffs, chases, head shakes, burst rises and spawning rushes (Table 1).…”

“…However, measured received levels ( Figure 9) and estimated source levels of sounds in this study provide a foundation to build upon as the mechanisms of sound production via swim bladder pathways and subsequent propagation and transition through the near and far-field become further understood (Fine & Parmentier, 2015). , short, y = 132.3 -20log 10 x, r 2 = 0.42) due to transmission loss of estimated mean source levels from spherical spreading are provided for comparison epinephelids as courtship associated, because spawning was unable to be observed or concurrent sound recorded (Mann et al, 2010;Nelson et al, 2011;Schärer et al, 2012aSchärer et al, , 2012bSchärer et al, , 2014. However, within some studies, levels of sound production increased during hypothesized times of spawning.…”

“…As fishes produce sounds associated with agonistic, disturbance and reproductive behaviours (Lobel, 1992;Lobel et al, 2010;, visual observations coupled with passive acoustic monitoring have increasingly been used to characterize spatio-temporal patterns of habitat use, courtship, spawning and acoustic behaviours in a number of epinephelid species (Mann et al, 2010;Nelson et al, 2011;Schärer et al, 2012b;Rowell et al, 2015), including the yellowfin grouper Mycteroperca venenosa (L. 1758) (Schärer et al, 2012a) and black grouper Mycteroperca bonaci (Poey 1860) (Schärer et al, 2014;Locascio & Burton, 2016;Sanchez et al, 2017), which are native to the western Atlantic Ocean and the closest living relatives to M. jordani (Craig & Hastings, 2007 (Bertucci et al, 2015;Mann & Lobel, 1998;Nelson et al, 2011), thereby permitting the monitoring of validated, acoustic behaviours using passive acoustics outside of observational periods (Rountree et al, 2006). With knowledge of the behaviours associated with sound production during spawning aggregations, long-term acoustic monitoring complement visual observations to deduce the daily timing and seasonality of spawning (Schärer et al, 2012a(Schärer et al, ,b, 2014 and estimate abundances remotely from recorded sound metrics .…”

The reproductive and acoustic behaviours of Gulf grouper Mycteroperca jordani were studied at a spawning aggregation site in the southern Gulf of California, México. In May 2015–2017, divers located and surveyed a spawning aggregation site within Cabo Pulmo National Park. Adult M. jordani conformed to a lek mating system in which large males formed territories over sand adjacent to a rocky reef that were spatially segregated from smaller females outside of courtship and spawning periods. Females moved into male territories during evening hours to spawn. Male courtship behaviours targeted a single female, included head shakes and burst rises and preceded pair spawning prior to sunset. Males and females displayed three shared colour phases, but four phases were sex‐specific. During evening hours, courtship and spawning, both sexes exhibited sexual dichromatism concurrent with reproductive behaviours. The pair‐spawning mating system and observations of bimodal size distributions by sex support previous claims of protogyny in the species. Males produced sounds during territorial patrols, courtship and spawning rushes, which corroborated the importance of acoustic communication within the behavioural repertoire associated with spawning. Long‐term acoustic monitoring revealed increases in total sounds detected day−1 from March through June with diel increases (e.g., evenings) that may be indicative of the spawning season. Observations of spawning on 12 consecutive evenings in May 2017 coupled with extended periods of sound production suggest that spawning does not follow a lunar rhythm. This first description of the mating system and sounds of the endangered M. jordani facilitates future development of seasonal and areal protections to restore and manage the species.

“…Though many marine organisms produce sounds and contribute to the biological component of soundscapes (Myrberg 1981; Versluis et al 2000;Bouwma & Herrnkind 2009; Scharer et al 2014; Staaterman et al 2014), few are as ubiquitous as snapping shrimps whose snaps contribute a significant portion of energy to the biological din (Au & Banks 1998; Radford et al 2008a, 2010; Bohnenstiehl et al 2016). By rapidly closing the dactyl of its enlarged chela, a snapping shrimp creates a cavitation bubble that produces a loud pop upon its collapse (Versluis et al 2000).…”

6Human use of the ocean and its ecosystems continues to degrade coastal habitats around the 7 world. Assessing anthropogenic impacts on these environments can be cost and manpower 8 intensive; thus, developing rapid, remote techniques to assess habitat quality has become 9 increasingly important. We employed autonomous hydrophone receivers to record the 10 soundscapes of healthy hard-bottom habitat in Florida Bay, Florida (USA) and hard-bottom 11 areas impacted by sponge die-offs. We also recorded sounds emanating from individual 12 sponges of three species that were isolated in underwater sound booths, and then enumerated 13 the invertebrates (mostly snapping shrimp) dwelling within the canals of each sponge. From 14 these recordings, a modified cylindrical sound propagation model was used to estimate 15 distances to snapping shrimp snaps. Using the program Distance, which applies distance 16 sampling theory to cue count surveys, we estimated snapping shrimp population density and 17 abundance within both habitat types. More snapping shrimp snaps per unit time were recorded 18 in healthy hard-bottom areas as compared to degraded hard-bottom areas. In addition, the 19 average distance to a snap source was greater within degraded hard-bottom areas than within 20healthy hard-bottom areas. As a consequence, the estimated density and abundance of 21 snapping shrimp were one to two orders of magnitude greater within healthy habitat than 23 modeling to rapidly assess populations of soniferous benthic indicator species, whose 24 vocalizations may yield indirect estimates of habitat quality. 25 26

1. Passive acoustic monitoring (PAM) is a non-invasive technique that uses hydrophones to monitor populations and ecosystem dynamics. Although many applications of PAM have been developed in recent years, it has never been used to identify a calling marine species.2. The south pass of Fakarava Atoll, French Polynesia, hosts spawning events of many reef fish species, including the camouflage grouper Epinephelus polyphekadion, with a spawning aggregation abundance exceeding 17 000 individuals during the full moons of June and July.3. The current study aimed to use PAM to distinguish camouflage grouper sounds among the vocal activities of all fish recorded during the aggregation periods. Audio recordings analysis resulted in the identification of 29 sound types, some of which showed diel and lunar patterns.4. Temporal analysis of these sounds in relation to spawning activities allowed the identification of camouflage grouper calls. These calls can be described as a single pulse or a series of 'boom(s)' with a pulse duration of ~44 ms and a low dominant frequency of 103 ± 31 Hz. Video recordings show that the camouflage grouper produces the 'booms' to initialize spawner ascent and to promote synchronous gamete release into the water column.5. The study highlights for the first time that PAM can be used to identify the previously unknown sound of a fish species. Moreover, we can use it to understand the phenology of some biological activities for improving the resolution of fish biodiversity assessments.
