Fish from any species can have worms in their meat. They are NOT harmful to humans, but can be unsettling. If your worried about it, you can hold a fish fillet up to a bright light, and you will see the small dark spots were the worms are(kind of like candling an egg). Then you can cut out the piece with the worm and use the rest.No need to waste the whole thing. As with all types of meat, cooking well is a good bet.
