HADDOCK (Gadus aeglefinus), a fish which differs from the cod in having the mental barbel very short, the first anal fin with 22 to 25 rays, instead of 17 to 20, and the lateral line dark instead of whitish; it has a large blackish spot above each pectoral fin - associated in legend with the marks of St Peter's finger and thumb, the haddock being supposed to be the fish from whose mouth he took the tribute-money.
In the cod and haddock the base of the first anal fin is not, or but slightly, longer than that of the second dorsal fin; in the whiting, pout, coal-fish, pollack, hake, ling and burbot, the former is considerably longer than the latter.
Unlike the cod and haddock, the coal-fish is, to a great extent, a surface-swimming fish, congregating together in large schools, and moving from place to place in search of food; large specimens (3 to 32 ft.
Though cod is much the most important fish (in 1905 fresh cod were valued at $991,679, and salted cod at $696,928), haddock (fresh, $1,051,910; salted, $17,194), mackerel (value in 1905, including horse mackerel, $970,876), herring (fresh, $266,699; salted, $114,997), pollock ($267,927), hake ($258,438), halibut ($218,232), and many other varieties are taken in great quantities.
Hake, ling, haddock, &c. The most important centres of the cod-liver oil industry are Lofoten and Romsdal in Norway; the oil is also prepared in the United States, Canada, Newfoundland, Iceland and Russia; and at one time a considerable quantity was prepared in the Shetland Islands and along the east coast of Scotland.
The take of 1898 consisted chiefly of cod, haddock, lobsters, mackerel, alewives, pollock and hake, but was valued at only $48,987, which was a decrease of 67% from that of 1889; in 1905 the total take was valued at $51,944, of which $32,575 was the value of lobsters and $8166 was the value of fresh cod-the only other items valued at more than $loon were soft clams ($2770), Irish moss ($2400), alewives, fresh and salted ($1220), and haddock ($1048).
The fish mostly caught are cod, haddock and herrings, while Heligoland yields lobsters, and the islands of Fhr, Amrum and Sylt oysters of good quality.
The principal catch is haddock and herring.s.
Twenty-eight boats engaged in haddock-fishing at Eyemouth used between October 1882 and May 1883 920 tons of mussels (about 47,000,000 individuals), costing nearly £1800 to the fishermen, about one-half of which sum was expended on the carriage of the mussels.
The next in order are haddock, cod and plaice, and the east coast fisheries return the greatest bulk of these also.
But whereas the south coast has the advantage over the west in the herring and plaice fisheries, the reverse is the case in the haddock and cod fisheries, haddock, in particular, being landed in very small quantities at the south coast ports.
In the inland waters salmon, trout, togue (Salvelinus namaycush), pickerel and bass abound; along the shore there are lobsters, clams and scallops (Pecten irradians); and off the shore are herring, alewives, mackerel, cod, halibut, haddock, smelts, hake, menhaden, porgies and porpoises.
Maine markets more clams than any other state in the Union, and the catches of cod, hake, haddock, smelt, mackerel, swordfish, shad, pollock, cusk, salmon, alewives, eels and halibut are of importance.
