Press release from the California Department of Fish and Wildlife:. The California Department of Fish and Wildlife (CDFW) will open the commercial Dungeness crab fishery from the Sonoma/Mendocino county line to the U.S./Mexico border beginning Jan. 5, 2025, at 12:01 a.m. with pre-soak to begin on Jan. 2, 2025, at 8:01 a.m. This area (Fishing Zones 3, 4, 5 and 6) will be subject to a 50 percent trap reduction. The trap reduction is expected to reduce entanglement risk for humpback whales by decreasing the amount of gear and vertical lines in the water.
