Got some info on black spots from the biologists.
Thanks for all the responses.

Yes. I heard about these things in freshwater fish that live in the waterways. The NH Fisheries guy said that they are collectively called "Black Grubs" and that cooking the fish kills these grubs and the fish, and the grubs, are safe to eat. Thank you. But, the reality is that now that I know what to look for and can see that there are worms in my food. However, towards the end of the summer, like in mid to late August, I noticed that these grubs have fallen out of the fish - I guess onward to their next meal.

We have nematodes in most bluegills and crappies caught in a specific lake but are absent in others. They as well are safe to eat after cooked but I don’t think I’d want to go the sashimi route with them.

Chief... I did some other research on this, couldn't read your attachment. We're talking Trematodes here. Black spots are byproduct if them residing on or in the fish, kinda like a scab. Experts say they cannot survive in a human, just some things like raccoons and others , but then say : cook the fish to 140° Internal temp.
Confused still. 140 is not gonna give ya a moist palatable meal, so I would stay away from it.All this info easily accessed on the web. Too much to go into cuz I'm lazy, and have never even considered eating these spotty critters.
Research explains their life cycle and residential vectors for those that are interested.

My info from the biologist say pretty much what you said. It does go into the life cycle. Thanks
