Which part of blue fish is not edible?

Question

I bought a blue fish caught in Maryland. Can I eat the entire fish, or are there some parts of it which are not edible?

Answer 1

From Fishing Tips: How to Catch, Prepare, and Cook Bluefish:

When you clean the fish, remove the skin and any dark-colored flesh. This part of the fish is especially strong tasting and somewhat oily.
