The Spiny Dogfish is a type of small shark and one of the best known of the dogfish. There are actually several species to which the name is applied, but all are readily distinguished by their having two spines, one in front of each dorsal fin, and their lack of an anal fin. They are members of the family Squalidae in the order Squaliformes.
The most widespread of the spiny dogfish is the grey-speckled Squalus acanthias, the common spiny (or piked) dogfish, which is found in shallow waters in most parts of the world. It can grow to around 60 cm in length and weighs about 2-3 kg. It particularly prefers temperate waters and migrates seasonally to find water of a comfortable temperature. It feeds on small fish and invertebrates, and can be present in such great numbers that it can seriously impact commercial fisheries.
Spiny dogfish are themselves 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. The fins and tails are processed into fin needles and are used in less expensive versions of shark fin soup in Chinese cuisine.
In England it is sold in "fry shops" as "rock salmon", in France it is sold as "small salmon" (saumonette) and in Belgium it is sold as "sea eel" (zeepaling).
