 Some Gulf Coast states such as Florida and Louisiana prohibit the harvesting of whole stone crab, allowing for declawing only.In contrast, declawing Jonah crab in Maryland was banned after 2015 unless a vessel could prove it had historically conducted the practice and was registered in a state where the practice was allowed.The central argument for declawing is that because crabs can regenerate lost limbs, it is inherently more sustainable than the capture of whole crabs.
