When preparing a whole crab for use, the viscera should be cleanly removed since it may contain heat-resistant bio toxins. The yellow substance inside the shell, which is sometimes called the crab butter, is the hepatopancreas, the digestive gland, which is equivalent to our liver and pancreas. Some people consider this a delicacy, but if it is from crabs taken from polluted areas then it may contain contaminants such as PCBs or heavy metals

Dungeness Crab Sustainability Info
The window below is a link to the Monterey Bay Aquarium’s Seafood Watch program info on Dungeness Crab. Size limits and restrictions on harvesting any female crabs are the primary conservation measures in place for the Dungeness crab fishery. Different fisheries employ different restrictions to maintatin the species. Size limits vary between 6 to 6 1/2 inches across the maximum breadth of the shell. This rule is designed to protect sexually mature males for at least 1 year and all female crabs since the female species rarely grow to this size. Other conservation measures being used by some fisheries include biodegradable escapement devices on traps to limit ghost fishing, escape holes to allow small crabs (including females) out of the traps, fixing the number of boats and traps along with seasonal closures
