Fishing Impacts
Monterey Bay
Why is it a concern?
Fishing, both recreationally and commercially, is an important activity that takes place in all sanctuaries and is a vital part of the blue economy. Although many harvested stocks are at or above fisheries management targets, marine resource managers are concerned about the depressed levels of certain stocks, habitat threats from some fishing gears, by-catch of sensitive species, and potential community and ecosystem-level effects of overfishing. About 200 species are typically caught in the commercial and recreational fisheries, with the bulk of the commercial landings composed of sardine, anchovy, squid, Sablefish, Dover and Petrale Sole, mackerel, and Dungeness crab.
Recent involvement of the fishing community in research activities related to fish populations has increased in the sanctuary. Working together, we seek to increase the public’s understanding of fishes, their role in the ecosystem, the various fishing activities that occur in the sanctuary, and how they are managed. The Fishing-Related Education and Research Action Plan provides strategies to expand the knowledge base of the public about fishery management in the sanctuary and increase public education about sustainable fisheries. The sanctuary staff has also partnered with researchers to study the impact of benthic trawling on seafloor habitats and associated benthic fauna in central California. Staff is also partnering with The Nature Conservancy, NOAA National Marine Fisheries Service, California State University Monterey Bay, and Morro Bay fishermen to study the impacts of modified groundfish trawling practices on soft sea-floor habitats and the time it takes for seafloor habitats to recover from trawling.

Science Needs and Questions
- What are the recovery rates and dynamics of community structure after trawling has occurred?
- How have the MPAs impacted the biologic and habitat resources within and outside the protected areas over different temporal scales?
