Based on the response, I'd say its not worth reporting unless you catch multiple fish with the spots, which would indicate an detrimentally large population of snails and poor water quality. I'm still no expert, of course!Forrest

That's good to know it isn't too serious. I caught a lot of other fish that day (smallies, crappie, sunfish, and a few other chubs) with no black spots that I noticed, so hopefully that stream doesn't have any excess nutrients in it. Would it still be worth reporting to VDGIF?

I have never personally seen that amount of black spot on an individual brook trout. It is much more common for us to see black spot on other fish species like creek chubs, blacknose dace, common shiners, and other minnows. The "black spot" (grub) needs a snail and a fish eating bird to complete its life cycle. Where we see a high volume of black spot there is often high densities of snails. Snails feed on attached algae which is driven by higher inputs of nutrients. Thank you for sending the picture. The brook trout in the picture should live a normal life. Black spot is a natural parasite found in streams throughout Augusta County. While I am not overly concerned, I would be interested in knowing the tributary where the trout was caught. Excess nutrients enriching the stream (increasing the snail population) could lead to degraded water quality.

I was wondering if yall have seen this on other Virginia streams, rivers or fish? My google searches seem to show it mainly existing in Northern states. I understand that it can kill the fish, but is it something that ought to be reported to VDGIF?Any thoughts?Forrest
