Well Bob the Dogfish we eat here is also known as Rock Salmon or Huss. I suspect that it is almost always the Lesser Spotted Dogfish 'Scyliorhinus Canicula' although the Starry Smooth Hound 'Mustelus Asterias' and the Spurdog 'Squalus Acanthias, are eaten too. These have less ammonia than other varieties, and if you can be bothered to skin them, which is hard work, they make good eating. Being what I believe is called cartiliginous, they only have one central bone, and thus are easy to eat, there being no finicky little bits to trap the elderly and unwary. Anyway Rock and Chips is food for the gods, but we can't get it here in Scotland, where the fish mainly used for fish and chips is the Haddock.
