With Oregon's liberal limits on both Dungeness and Red Rock Crabs, It makes one wonder how many spoil and are thrown into the garbage because the crabbers did not know how to shake them? Shaking crab cuts the time it takes to pick them by half.
How to humanly kill Dungeness and red rock crabs is the question my wife wants me to answer. She can't stand to see anything suffer. Striking the Thoracic ganglion with a crab mallet kills the crab immediately. The crab does not suffer as it would if submerged in boiling water and neither does my wife. Killing and backing the crabs prior to cooking them shortens the total time it takes to cook and clean large numbers of crabs.
Zach demonstrates his method to kill and prepare the crabs for cooking as shown in the following video clip.
