Atlantic cod Gadus morhua populations in the northeast USA have failed to recover sincemajordeclines in the1970sand1990s.Torebuild thesestocks,managersneedreliable information on spawning dynamics in order to design and implement control measures; discovering costeffective and non-invasive monitoring techniques is also favorable. Atlantic cod form dense, sitefidelic spawning aggregations during which they vocalize, permitting acoustic detection of their presence at such times. The objective of this study was to detect spawning activity of Atlantic cod using multiple fixed-station passive acoustic recorders to sample across Massachusetts Bay during the winter spawning period. A generalized linear modeling approach was used to investigate spatiotemporal trends of cod vocalizing over 10 consecutive winter spawning seasons (2007−2016), the longestsuchtimelineofanypassiveacousticmonitoringofafishspecies.ThevocalactivityofAtlantic cod was associated with diel, lunar, and seasonal cycles, with a higher probability of occurrence at night,duringthefullmoon,andnear theendofNovember.Following2009and2010, therewasageneraldeclineinacousticactivity.Furthermore, thenorthwestcornerofStellwagenBankwasidentified as an important spawning location. This project demonstrated the utility of passive acoustic monitoring in determining the presence of an acoustically active fish species, and provides valuable data for informing the management of this commercially, culturally, and ecologically important species.
