If a blue crab grew as large as a lobster, there would not be a market for lobster.
Blue Crab is delicious. But it's a lot of work. Cleaning a crab doesn't give you nearly the amount of meat you get from a lobster and lobster's clean easier.
That said, we took the boat out this morning and dropped 6 crab pots. We'll pick them up on Friday and see what we got.
