This project target cod (Gadus morhua), a widely distributed and important species throughout the Atlantic ocean, with hearing range and sound production overlapping with seismic airguns, as well as spawning sites located in the central north sea where the majority of the seismic activity are conducted, thus causing a major management challenge.
Important spawning sites in Lofoten also makes it highly relevant in terms of assessing potential oil exploitation. Successful reproduction are essential for stock recruitment, and sound production and hearing are essential during cod spawning, as successful mating relies on vacillation to time release of spawning products. Spawning may hence be impacted in terms of a) hampered vocalization/masking or b) avoidance of spawning site due to exposure. This project will explore both vocal behavior and movement in time and space, as well as investigate the quality of spawning products in exposed and control groups. Exposure will be done with a downscaled air gun.
We will work in close collaboration with a large international consortium targeting to assess the population level effects of seismic exposure on cod. This will contribute to exchange ideas, experience and results. Project results are directly applicable into management of fish stocks during seismic surveys, and results obtained will be used to define mitigation to minimizing impact of seismic surveys on fish, but avoiding unnecessary mitigation restrictions, aiming at a better coexistence between the fishery and oil industry.
