Fish sound production and acoustic telemetry reveal behaviors and spatial patterns associated with spawning aggregations of two Caribbean groupers

Abstract: Regional abundances of Nassau grouper Epinephelus striatus and yellowfin grouperMycteroperca venenosa have declined due to overfishing of their spawning aggregations, prompting permanent and seasonal fisheries closures in the US Virgin Islands (USVI). As both species produce sounds associated with reproductive behaviors (courtship-associated sounds; CAS), passive acoustic and acoustic telemetry methods were used to determine temporal patterns of reproductive activity, site usage, and fish movements in order to… Show more

“…Passive acoustic telemetry is a technique by which focal animals can be tracked using a fixed array of hydrophones, previously used extensively with marine mammals (e.g. Soldevilla et al 2014, Miller et al 2015, where animals are detected from their vocalizations, and fish, where animals are equipped with individualized transmitters that are de tected by receivers (Heupel & Hueter 2001, Rhodes & Tupper 2008, Rowell et al 2015. Al though it can be costly in terms of the initial financial input for receivers and transmitters, and the routine maintenance of equipment, this long-term monitoring enables the continuous collection of data not influenced by survey effort or observer presence (Lowe et al 2006, Cooke 2008, Zeh et al 2015.…”

“…Sound production did not exhibit patterns in relation to lunar phase, as has been described in a number of related species (Rowell et al ., ; Schärer et al ., ), indicating that courtship and spawning may occur continuously during the reproductive season and are not driven by lunar forces. This claim is supported by observations of spawning occurring from 2 dbfm to 13 dafm, a duration that exceeds the number of days typical for epinephelids that spawn following lunar periodicity (Nemeth, ).…”

“…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 .…”

“…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. Traditionally, FSAs are monitored by using diver surveys and analysis of gonadal-somatic indices (GSIs).…”
