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.

Genera and species

The family gadidae includes 24 species, grouped into 13 genera. Some other forms once included here have since been removed to other families. On the other hand, the tadpole cod family Ranicipitidae has now been absorbed into Gadidae, having formerly contained just one species, the tadpole fish (Raniceps raninus).
