The spiny dogfish, spurdog, mud shark, or piked dogfish, Squalus acanthias, is one of the best known species of the Squalidae (dogfish) family of sharks, which is part of the Squaliformes order.piny dogfish are fished for food in Europe, the United States, Canada, New Zealand and Chile. The meat is primarily consumed in England, France, the Benelux countries and Germany.
Some species, such as spiny dogfish and porbeagle, are targeted primarily for their meat. The oceanic whitetip, porbeagle and three hammerhead species are some of the shark species of concern for WWF, where the impact of trade is contributing to declines in populations. Millions of these sharks continue to be fished annually to supply the persistent demand for their fins and meat.
