Theses - ALL
Climate change has the potential to impact many aspects of an organism’s biology, including phenology, the timing of important biological events. The timing of reproduction and spawning events for commercially important fish species is a critically important area of research for fisheries management. Haddock (Melanogrammus aeglefinus) are commercially important as well as sound-producing, which allows for monitoring via non-invasive passive acoustics. This study presents an application of passive acoustic monitoring to a multi-year dataset to increase understanding of haddock sound production, as well as trends in spawning phenology and behavior. An automatic acoustic detector was able to identify haddock calls …
