Mysis Shrimp contaminant? Bycatch?

Is it likely, or even possible, that's what it was? (It'd be a lifer for me!) Any other weird stuff you folks have had show up in your frozens?

I'm not surprised about some amount of by-catch included ... these are after all quite small critters ... but mysids are salt-water and pygmy killies (Leptolucia ommata) are strictly freshwater AFAIK, I've never seen or heard of any in brackish water.
Fundulus similis (longnose killie) have distinct thin black vertical bars even at a tiny size, that'd seem like a more likely candidate to me. But similis would have bars from end to end, and "beefy" would not be part of the normal description. Ditto for F. confluentus (marsh killie), although those prefer brackish to fully salty water.
Small Cyp. variegatus (so-called sheepshead "minnow") also can have well-defined dark markings on the rear section, although they look usually more like spikes than true bars. And that is a chunkier fish.

I don't know how a lot of foods are cultured, including mysis. (I thought mysis was a species, but apparently it's a life-stage.) So I was wondering about the possibilities of what species might even be in there. Thought about trying to take a picture of it, but Blaylock and Co would never let me hear the end of it!

Not to throw a wrench in the conversation, but Piscine Energetics, which is the biggest supplier of mysis that I know of, harvests freshwater mysis from Canadian lakes. The shrimp are invasive, yadda yadda ya...(scroll down on the link provided to watch a quick video). The point I'm getting at is that there are more species options possible since your source was FW. (Matt, did you happen to use P.E. Mysis?). Now you'll just have to look up what other small or juvenile species it could have been from that region.
