      The populations of harvestable Dungeness crabs are low in both areas 11 based on pre-season test fisheries, Sizemore said. Additionally, Dungeness crab harvests have fallen 88 percent in Marine Area 11 and 90 percent in Marine Area 13 since the season. Input from recreational crabbers also indicates support for the closures.

Furthermore, for early Dungeness crab life stages in the near-future, the prediction of more frequent and prolonged exposures to more severe ∆Ω cal,60 gradients (Turi et al., ) could have potentially deleterious consequences in terms of behavioral and sensory impairments and chelae function.
