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.
Fish are caught in great numbers in the rivers and marshes, chiefly barbel and carp, and the latter attain so great a size that one is a sufficient load for an ass.

Freshwater scale-fish are mostly full of bones, but fine eels and barbel are plentiful in the rivers.
