Gadidae is a family of marine fish, included in the order Gadiformes.
Most species of gadid are found in temperate waters of the northern hemisphere, although there are some exceptions. They are generally medium sized fish, and are distinguished by the presence of three dorsal fins on the back and two anal fins on the underside. Most species have barbels on their chin, which they use while browsing on the sea floor. Gadids are carnivorous, feeding on smaller fish and crustaceans.
Gadids are highly prolific, producing several million eggs at each spawning. This contributes to their high population numbers, which, in turn, makes commercial fishing relatively easy.
