Summary

This scientific study analyzes ~16 cumulative recording-years of passive acoustic data (2018-2022) from seven sites in Monterey Bay and Channel Islands National Marine Sanctuaries to model environmental drivers of fish chorusing—when many fish call simultaneously, often for mating. The research focuses on three species: plainfin midshipman, bocaccio rockfish, and white seabass, examining how temperature, upwelling, and habitat conditions shape chorusing behavior and intensity.

Fish chorusing is when many fish call at the same time, often for mating purposes.

We can use passive acoustic monitoring to track when and where fish choruses occur, but the roles of oceanographic and habitat conditions in shaping chorusing and its intensity remain poorly resolved.

Here we used ∼16 cumulative recording-years of passive acoustic data from 2018 to 2022 across seven recording sites in Monterey Bay and Channel Islands National Marine Sanctuaries to model environmental drivers of chorusing by plainfin midshipman, bocaccio rockfish, white seabass.
