I would cut one open, I once found a wolf spider with a very distended abdomen. Inside, after much unraveling was a 24 inch horsehair worm.
Or could it be damage during the softshell stage though it looks awfully symmetrical for damage, or parasites.

Where are these bulges? Are you sure you don't have C. acuminatus? Edges of those rostrum look pretty thick.
Look at the lighter patches on the last 2 crayfish. I have never seen them on any other C.bartoni. I wish they were another species of crayfish but the only Cambarus known to live in NJ are bartoni and diogenes.
One of the main reason I'm not a biologist is that I don't like cutting things open so a dissection isn't likely
