When eating dogfish, there are concerns about mercury levels (as with almost any long-lived, predatory fish that bioaccumulates mercury)- so I wouldn't do it every day wink

Here are just a few market names under which Dogfish (Squalus Acanthias) are sold around the world:

Sand Shark, Gray Fish, Rock Cod, Rock Salmon

Doesn't ROCK SALMON sound so much better to eat than Dogfish!
