Shrimp question

In my many years of peeling, deveining and cooking shrimp, I've never seen what I saw tonight: what is it?

Mixed in with the black intestinal goop was a whitish, firm substance that almost looked like tiny styrofoam balls-- but it was clearly part of the shrimp. Only a couple of the shrimp had this. One had a little bit, and the other a fair amount, running along the whole vein canal

Thoughts?

  1. Farm raised shrimp? From India or Indonesia or Thailand or somewhere like that? Who knows what they feed those things. Nobody likes to talk about it, but farm raised shrimp do not come from the most pristine of places.

      In India at least, Prawn Feed

       
    2. This was in raw shrimp? Sounds like immature eggs/roe. Cook it up and if it turns red then its roe. (And it's good.)

        I've seen that in my shrimp before as well. I've always assumed it was the beginning of the egg sack as well (though I really am not sure of this). It won't turn red when it is cooked, though I think if the shrimp were still alive it would eventually turn pink/red once the eggs become more mature.

          I was thinking about that, except the original poster said that these balls are on the back.

            No, the OP said "Mixed in with the black intestinal goop"

              Yeah, but the intestine track is on the back. The nerve is on the bottom (belly).

                In the back as opposed to on the back. Where the Eggs are formed, when mature they are extruded on to the Belly

        2. I've seen it in the shrimp I get here on the NC coast. Not often, but I definitely know what you're describing. Don't know what it is either, but I'm confident it's not any type of roe or fish eggs. Guess I was always afraid to ask what it was. Didn't really want to know. I'll ask my fishmonger next time I see him and report back....

            It is amazing that you people have confirmed seeing these. I have never seen them.

          2. My first thought too was eggs. But my second thought was maybe the shrimps swam up to the surface and munched on a piece of stray styrofoam buoy. I do tend to suffer from an over active imagination though.

              What I've seen is maybe different from what the OP was describing in terms of texture. The white stuff I've found has definitely been "biological" in nature.

              And while I like the idea - I'd be surprised if shrimps' mouths are large enough to actually ingest styrofoam but maybe.

                Maybe I should have used the word nibble. It was just a thought.:-)

            2. Next time when you remove them put them it some water. If they float the shrimp has been eating Styrofoam. Not that uncommon as the Styrafoam absorbs 'flavors' and the poor shrimp see a piece of the stuff the size of a Beetle and think they've reached food nirvana. God knows there's enough of it floating all over the oceans.
