Gadus macrocephalus Tilesius, 1810. Gray Cod, Pacific Cod, or True Cod. To 120 cm (47.2 in) TL (Morrow
1980). Yellow Sea off Manchuria, China to Bering Sea, Aleutian Islands, and Gulf of Alaska (Mecklenburg
et al. 2002) to Santa Monica, southern California (Miller and Lea 1972). Well documented north
almost to Bering Strait (Mecklenburg et al. 2002); reported to Chukchi Sea (Barber et al. 1997), but
documentation lacking (Mecklenburg et al. 2002). Benthic, also pelagic over deep water, near surface to
depth of 875 m (2,871 ft; Allen and Smith 1988); sometimes in surf zone (Miller et al. 1980).
Gadus ogac Richardson, 1836. Greenland Cod or Ogac. To 71.1 cm (28.0 in) TL (Coad 1995). Beaufort Sea
off Alaska to west coast of Greenland and western Atlantic to Gulf of St. Lawrence and Cape Breton
Island; disjunct population in White Sea (Cohen in Cohen et al. 1990). Near coast from surface to 200 m
(656 ft; Cohen in Cohen et al. 1990), occasionally offshore to depth of 400 m (1,312 ft; Coad 1995).
Reported from Chukchi Sea but this report seems to be a mistake, and even those from Beaufort Sea are
not well documented (Mecklenburg et al. 2002). Molecular evidence indicates G. ogac is a synonym of
G. macrocephalus (Carr et al. 1999); like Nelson et al. (2004), we await confirmation from other studies
before making this change.
Microgadus proximus (Girard, 1854). Pacific Tomcod or Tomcod. To 37 cm (14.6 in) TL (Mecklenburg et
al. 2002). Southeastern Bering Sea and eastern Aleutian Islands (Mecklenburg et al. 2002) to Point Sal,
central California (Miller and Lea 1972). Demersal, sometimes enters brackish waters, near surface
(young fish; Eschmeyer and Herald 1983) to 275 m (905 ft; Allen and Smith 1988); sometimes in surf
zone (Miller et al. 1980).
Theragra chalcogramma (Pallas, 1814). Pacific Pollock or Walleye Pollock. To 91 cm (36 in) TL (Clemens
and Wilby 1946). Seas of Okhotsk and Japan (Okamura in Masuda et al. 1984) to southern Chukchi
Sea (Barber et al. 1997), Bering Sea, and Gulf of Alaska (Allen and Smith 1988) to Carmel, central
California (Miller and Lea 1972). Generally demersal, also taken pelagically near surface and in midwater
(Mecklenburg et al. 2002), to depth of 1,200 m (3,921 ft; Hoff and Britt 2003); sometimes in surf zone
(Miller et al. 1980).
