Most of the fishermen used the name codling for any cod which was not full-grown. A distinction between sprag (a half-sized cod) and codling (a very tiny cod) was only made by informants I, II, III, VI. Informant XII called a very tiny cod "pout or fry" and used sprag as another name for cod. Pout is a name applied to various kinds of fish (OED). SND lists it as a name applied to any small or young creature. Fry also is a collective term for the smaller kinds of fish and young fishes (OED). A half-sized cod was called blockie by informant VIII.

SND lists block as being used for cod in Banffshire. Blockie is given as the name for a half-sized cod on the east coast of Scotland in GNF.
