Atlantic cod Gadus morhua Linnaeus, 1758 200 cm 100 cm 96.0 kg 25 years 4.4 [4] [5] [6] VU IUCN 3 1.svg Vulnerable[7]
Pacific cod Gadus macrocephalus Tilesius, 1810 119 cm cm 22.7 kg 18 years 4.0 [8] [9] [10] Not assessed
Alaska pollock Gadus chalcogrammus Pallas, 1811 91.0 cm cm 3.85 kg 15 years 3.5 [11] [12] [13] Not assessed [14]

Modern taxonomy included Alaska pollock (Gadus chalcogrammus), which is genetically not separate from Norway pollock.[15][16] Greenland cod (G. ogac) that was considered an own species, is considered the same species as Pacific cod (G. macrocephalus).[16][2][3]
