I Google this and found several articles. The dots are parasites. The fish you caught are smallies.
This is one article I found....
What are the black dots in the flesh of some Smallmouth Bass?lighthouse_lover92 says: November 5, 2008 at 12:43 am The parasites that are on the bass are right under the skin not in the meat. We have caught and eaten the fish. Just make sure that you remove the parasites first. If there are a few hundred on them I wouldn’t eat them, but if there are one or two you should be ok. I live in Pa and our smallmouth bass have the same problem just not as bad.

Although aesthetically displeasing, none of these parasites presents a threat to human health provided the fish is thoroughly cooked before it is eaten.
