Marine Mammals on the West Coast: Fisheries Interactions
The West Coast Region closely evaluates the impacts of fisheries activities on marine mammals and develops and implements measures to minimize effects.
NOAA Fisheries is responsible for managing the impacts of commercial and recreational fisheries on marine mammals under the authority of the Marine Mammal Protection Act, Endangered Species Act, and the Magnuson-Stevens Act. There are programs and policies in place to monitor the amount of marine mammal bycatch that occurs in fisheries and to minimize impacts to populations when conservation concerns may be warranted. These programs address fisheries and conservation issues that involve fishing operations and marine mammals throughout U.S. and international waters. NOAA Fisheries also studies and manages the impacts of fishing on the health and behavior of marine mammals through various regulatory and conservation actions.
Interactions between fisheries and marine mammals include:
-
Incidental bycatch in fishing gear.
-
Predation by marine mammals on fish that are being targeted or already captured during fisheries harvest operations (referred to as marine mammal depredation).
-
Removal of preferred marine mammal fish forage and prey by fisheries harvest.
The bycatch of marine mammals can occur:
-
During active fishing operations that involve mobile fishing gear.
-
In fishing gear that is fixed in place.
-
In fishing gear that has been lost, discarded, or is otherwise no longer being used for fisheries harvest (marine debris, otherwise known as derelict or ghost fishing gear).
