I think it is more of an issue can you eat the fish knowing they have parasites. As long as you get them hot enough, which is not an issue if frying, then you will kill them.
The black spots can be passed off as pepper, the white grubs not so much.
Either way I have eaten some of both, but have more issues with the grubs, and will not keep the fish if infested with them.
I cleaned a CC this past fall and the fillets were full of them. I went ahead and put the fish in the freezer in case it can be used during a fish fry, but not sure I want to cook it at all.
