That's how I do my crabs as I showed in the picture a few posts back and they all have the orange inside, some more than others. You just can't use females, because when you buy them you don't get a choice and you might be tossing half your dead crabs back, unless you only buy a few and a few won't last 10 minutes. You say your not a black fisherman, well if and when you do go have a great time and good luck. Green crabs are an invasive crab species from Europe, don't throw them back alive, they will destroy clams, mussels, oysters beds and others.
