Hello folks, looking for some ID help. I caught this guy in a freshwater effluent drain that flows into Bogue Sound, in central, eastern NC. I'm able to work it down to Macrobrachium but I seem to have run out of pages in my ID guides. Is there enough detail in this photograph for anyone to lead me one way or another? The body alone is about 3.5 inches long. Thanks in advance!

Darn good photo. I think it is at least ID quality. I hope someone can help you.

M. ohione is by far the most common sp in NC/SC, but there are also a few records of M. acanthurus and M. olfersii. I emailed you John Cooper's 2011 paper (Journal of the North Carolina Academy of Science, 127(2), 2011) which lists the NC/SC museum records for these 3 spp, but has no ID characteristics. Maybe the Lit Cited will help?

Thanks man, I always love the way shrimp photos turn out!

Gerald, I think I read every cited paper I had access to, and I am heavily leaning towards M. acanthurus. He (Or so I believe anyway) molted today and has turned this dark cinnamon color with lots of striping, I will try to get a better photo later on. I have him in a tank right now with your lyre gobies, but from what I have read in those papers, is a bad idea. I have never heard the words "very aggressive" and "shrimp" used together so many times before. Thanks for the help!

I had one once. Watched him come out from his burrow under a rock, grab an adult bluefin killie right out of the water, and eat the whole thing in about two minutes. The fish was at least half the shrimp's length, and a quick swimmer.

I've caught them in the Cape Fear River here in NC in minnow traps, the ones i caught were quite large, twice that size at least...
