Numbers of such entanglements have been climbing yearly. Whales caught in the ropes of crabbing pots can starve or die from infected wounds.

A spokeswoman for California’s Fish and Wildlife Department did not immediately return a request for comment. California recently passed legislation meant to encourage crabbers to remove unused crabbing gear from the ocean.
