What are these little creatures on the fish?

Question

I'm not a fisherman, but I just caught a cod fish (my first one) and found a lot of strange little creatures all over the fish:

What are those? Are they harmful to the fish, or to the human?

Edit: it's caught on Faroe Islands

Though it's hard to say exactly what you're talking about based on the image, that cod appears to have several sea lice on it:

Sea lice are common parasites of fish.
