Atlantic cod (Gadus morhua) produce distinct sonic clicks when approached by predator-like bodies. These sounds, recorded in controlled pool environments, may serve to startle predators.

Area of Science:

  • Marine Biology
  • Bioacoustics
  • Animal Behavior

Background:

  • Fish and marine mammals produce a variety of sounds.
  • The acoustic repertoire of Atlantic cod (Gadus morhua) is not well-documented.
  • Understanding fish vocalizations can provide insights into their ecological interactions.

Purpose of the Study:

  • To investigate the source and characteristics of conspicuous sonic click sounds recorded in the presence of Atlantic cod.
  • To determine the behavioral context associated with the production of these sounds.

Main Methods:

  • Acoustic recordings were made in a pool setting with cod (Gadus morhua) exposed to harp seals (Pagophilus groenlandicus), hooded seals (Cystophora cristata), or a human diver.
  • Control recordings were conducted with salmon (Salmo salar) and seals separately, and seals with salmon.

  • Analysis of recorded click sounds included peak frequency, duration, and sound pressure level.

    • Main Results:

    • Distinct sonic click sounds were exclusively recorded when cod were present and approached by a swimming predator-like body (seals or diver).
    • These sounds were not detected in the presence of salmon or when seals and fish were housed separately.
    • Analyzed clicks averaged a peak frequency of 5.95 kHz, duration of 0.70 ms, and sound pressure level of 153.2 dB re 1 microPa at 1 m.

    Conclusions:

    • Atlantic cod (Gadus morhua) are the source of the recorded sonic clicks.
    • The clicks are produced in response to the approach of potential predators.
    • The sounds may function as a predator-startling mechanism, though further research is needed to confirm the mechanism and purpose.
