Whiting (Gadus merlangus) is a fish of the same genus as the cod and the haddock, from which it may be distinguished by the absence of a barbel on the chin, the more slender form, and the presence of a dark spot at the root of the pectoral fin. It occasionally reaches a length of 53 centimetres. It is voracious and predaceous, living mostly on other fish. Females are twice as numerous as the males. Research Whiting
