The common name for this is black spot. The specks are tiny encysted larvae of various trema- todes which live in many species of fish. Although the larvae are harmless to humans, fish with heavy infections may be unappealing to eat. Skinning the fish often removes most of the cysts.

Why does my fish have black spots?
The black spots on your fish’s skin are literally parasite eggs that burrow into the fish skin.

The eggs harden for protection, and eventually, the eggs crack to release the parasite inside the fish skin.
