“…However, this may not be true for other locations; band levels incorporate all sources of sound within the selected frequency band, such as sound from boats, wind, other fishes, and marine mammals. If ALS had other aggregating soniferous species with either frequent or high-energy vocalizations within the 100 to 200 Hz band, such as yellowfin grouper Mycteroperca venenosa (Schärer et al 2012) or red grouper Epinephelus morio (Nelson et al 2011), band levels would have been influenced by the acoustic signals of these species. As a result, multispecies spawning aggregations may require the manual processing of acoustic data.…”

“…Sound production in a number of species is known to be associated with courtship, territoriality, or reproduction, warranting the use of passive acoustics to locate spawning aggregations (Luczkovich et al 1999, 2008b, Walters et al 2009, Rowell et al 2011) and determine temporal spawning behavior and habitat use by different species , 2010, Nelson et al 2011, Schärer et al 2012.…”

Annual spawning aggregations of red hind Epinephelus guttatus form at predictable times and locations and have historically succumbed to overfishing. Monitoring the status and restoration of aggregations is essential for evaluating the effectiveness of fishery management measures. Passive acoustic and diver-based underwater visual census (UVC) techniques were used to develop an efficient method for estimating red hind density from sound production at spawning aggregations. Red hind sound production was recorded from November 2010 to April 2011 at Abrir la Sierra, Puerto Rico. UVC surveys were conducted during the spawning season to assess changes in red hind density over a fixed time and area. Sound recorded from 18:00 to 19:00 h Atlantic Standard Time (UTC − 4) was representative of total daily changes in red hind sound production and was selected for the development of an efficient density estimation model. Pronounced daily changes in sound production and density were observed after the December 2010 and January 2011 full moons. Two hourly sound level measurements were compared to densities estimated by UVC surveys, yielding significant linear regressions, which were used to predict changes in fish density as measured at the aggregation site. Passive acoustic methods allowed to predict changes in red hind density and habitat use at a higher temporal resolution than previously possible with traditional methods. Red hind sound production and inferred densities can be monitored and analyzed efficiently for multiple aggregation sites simultaneously, documenting short-term and long-term changes in red hind densities at spawning aggregation sites and providing important information for the support or development of management strategies.

“…Although black grouper can spawn year-round (Crabtree and Bullock, 1998), the majority of their annual reproductive effort is spent seasonally during transient spawning aggregations (García-Cagide and García, 1996;Crabtree and Bullock, 1998). Only 3 spawning aggregations of black grouper have been described within U.S. territorial waters (Eklund et al, 2000;Schärer et al, 2014;Locascio and Burton, 2016). However, black grouper are believed to form many small spawning aggregations throughout their range (Paz and Sedberry, 2008).…”

“…Courtship sounds are common throughout the epinephelids (Mann et al, 2009Nelson et al, 2011, Schärer et al, 2012a, 2012b, and male black grouper are no exception, producing a species-specific courtship sound associated with spawning behavior (Schärer et al, 2014;Locascio and Burton, 2016). With passive acoustic monitoring, therefore, it is possible to conduct a more detailed analysis of the courtship patterns of black grouper than current methods allow (Rowell et al, 2011(Rowell et al, , 2015.…”

Abstract-Geomorphological assessments were conducted and passive acoustic recordings were collected from 2012 through 2014 at 3 recently identified spawning aggregations of the black grouper (Mycteroperca bonaci) in Puerto Rico and southern Florida. A time series of courtshipassociated sounds (CASs) by black grouper were analyzed in relation to lunar and diel periodicities, water temperature, and tidal stage. Analysis of CAS recordings indicated similar temporal patterns at the 3 spawning aggregations. Spawning season was correlated with decreased water temperature. Within the spawning season, CAS production was influenced significantly by lunar and diel periodicities and sound production peaked between the last quarter and new moons during evening hours. The data from this study also indicate a potential correlation with tidal stage. Temporal patterns were similar during 3 consecutive years at Mona Island in Puerto Rico and for the geographically isolated sites of Mona Island and Riley's Hump off Florida. At Bajo de Sico in Puerto Rico, courtship activity was lower than that at the other sites but reflected the same general patterns in 2014. For all 3 sites, spawning aggregations were found less than 150 m from a promontory at depths between 25 and 35 m near deep water (>100 m).

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.
