POGIE= Menhaden, Bunker, Moss Bunker. Same fish different naming conventions, all the same. There may be other fish as well that are referred to as bunker, pogie, etc. but the most common fish referred to as bunker, pogie is the menhaden. As far as Dogfish you are correct it is a small shark species of which I believe we have two main varieties. The smooth dogfish and the spiny dogfish and you are also correct they catch these fish out of Chatham for the fish and chips industry in England. I also think that some of the dogfish are marketed in asia for sharkfin soup and medicinal purposes.
Atlantic Menhaden: Brevoortia tyrannus
Distribution:Western Atlantic: Nova Scotia, Canada southward to Indian River, Florida, USA.
Family: Herrings, shads, sardines, menhadens; Found inshore in summer, but at least some moving into deeper water in winter. Adults are found in near surface waters (Ref. 38984), usually in shallow areas overlying continental shelf, in greatest abundance immediately adjacent to major estuaries (Ref. 4639). Juveniles are also generally pelagic, with smallest size groups farthest up river (Ref. 38986). Form large and very compact schools, both of juveniles and adults. Migrate north - south; also in and out of bays and inlets. Feed by filtering phytoplankton and zooplankton. High water temperatures apparently limit breeding. Spawn probably all year; nursery areas in estuaries. Larvae are pelagic (Ref. 38985), probably spend about a month in waters over continental shelf (Ref. 38983), entering estuarine waters at about 10 mm and larger (Ref. 844). Marketed fresh, salted, canned or smoked. Mainly used for production of oil, fertilizer and fishmeal (Ref. 188). Parasites found are isopods, copepod, cestodes and trematodes (Ref. 37032).
Atlantic Smooth Dogfish: Mustelus canis
Distribution: Western Atlantic: Massachusetts to Florida (USA), northern and western Gulf of Mexico, Venezuela, Cuba, Jamaica, Barbados, Bermuda, Bahamas; southern Brazil to northern Argentina; also western Gulf of Mexico and Antilles (Ref. 26938).
Family: Houndsharks; Found on continental and insular shelves and upper slopes, ranging from shallow inshore waters and the intertidal to 200 m, occasionally down to 579 m (Ref. 244). Occasionally found in freshwater. It is doubtful that this species can live in fresh water for an extended period of time (Ref. 244). Feeds on large crustaceans, mainly crabs, but also heavily on lobsters ( Homarus ) (Ref. 244). Probably non-territorial. Off the Atlantic coast of the USA, this species is migratory (Ref. 244). Viviparous (with a yolk-sac placenta), with 4 to 20 young in a litter. Longevity given as 7 years (Ref. 775) but appears too low. Utilized fresh, dried-salted, and smoked (Ref. 9987).
Spiny Dogfish: Squalus acanthias
Distribution: Western Atlantic: Greenland to Argentina. Eastern Atlantic: Iceland and Murmansk Coast (Russia) to South Africa, including the Mediterranean and Black Sea. Western Pacific: Bering Sea to New Zealand. Reports from off New Guinea are doubtful (Ref. 6871). Eastern Pacific: Bering Sea to Chile.
Family: Dogfish sharks; Possibly the most abundant living shark (Ref. 247). An inshore and offshore dogfish of the continental and insular shelf and upper slopes (Ref. 247, 11230). Usually near the bottom, but also in midwater and at the surface (Ref. 26346). Often found in enclosed bays and estuaries (Ref. 247). Reported to enter freshwater (Ref. 11980) but cannot survive there for more than a few hours (Ref. 247). Schools mainly segregated by size and sex; mixed schools also reported (Ref. 247). Feeds primarily on bony fishes, also mollusks, crustaceans and other invertebrates (Ref. 247). The only species of horned sharks that can inflict toxins with its tail. Utilized for human consumption, liver oil, vitamins, sand paper, leather, fertilizer, etc. (Ref. 247, 27436). Eaten fried, broiled, and baked (Ref. 9988). Growth is slow. At sexual maturity, males are 60-70 cm long, females 75-90cm (Ref. 35388). Gestation period is 2 years (Ref. 36731).
