To Eat or Not To Eat? (Warning: Contains Graphic Images)

[SquidJig]

Does anyone know what this stuff is? I've never seen before. It resembles beach tar, grainy, black, and a little tough to break apart. It's everywhere in this fish, in the gut cavity, in connective tissue, in the flesh. It ranges in size from grains of sand to flattened peas. I don't have a problem with nearly invisible worms but this stuff is down right ugly. The fish tasted fine but I couldn't eat it without shredding it and picking out all the black stuff.

So, is fish like this better off in the dumpster? I guess it can't all pass inspection, right?
