British Columbia (Peden 1975), and California (Eschmeyer and Herald 1983) to northern Chile (21°05'S,
71°07'W; Melendez and Sielfeld 1991). Oceanic, mainly mesopelagic and bathypelagic, at depths of
0–1,291 m (0–4,235 ft; Moore et al. 2003).
Family Bregmacerotidae — Codlets
Bregmaceros bathymaster Jordan & Bollman, 1890. East Pacific Codlet. To 10 cm (3.9 in) TL (De La Cruz-
Agüero et al. 1997). Tropical Pacific; off Bahia Magdalena, southern Baja California to Chile (De La Cruz-
Agüero et al. 1997), including Gulf of California (Galván-Magaña et al. 1996). Surface (SIO 63-632) to
at least 1,246 m (4,088 ft; LACM 21995.000).
Family Merlucciidae — Merlucciid Hakes
The common name for this family is correctly spelled with two is; often seen with one i.
Merluccius angustimanus Garman, 1899. Panama Hake. To 40 cm (15.7 in) TL (Cohen in Cohen et al. 1990). Off
Del Mar, southern California (Ginsburg 1954) to Colombia (Cohen in Cohen et al. 1990), including Gulf of
California (Inada in Fischer et al. 1995). At depths of 80–500 m (262–1,640 ft; Cohen in Cohen et al. 1990).
Merluccius productus (Ayres, 1855). Pacific Hake. To 91.4 cm (36 in) TL (Miller and Lea 1972). Attu Island,
Aleutian Islands (one record) and Gulf of Alaska (Mecklenburg et al. 2002) to Bahia Magdalena, southern
Baja California and Gulf of California (Miller and Lea 1972) to Mexcaltitán, southern Mexico (21°50'N;
Amezcua Linares 1996). Reported for continental slope of Bering Sea (Fedorov 1973), but vouchers are
needed to confirm continued existence there (Mecklenburg et al. 2002). Oceanic and neritic pelagic (Inada
in Cohen et al. 1990), at depths of 12–1,400 m (39–4,593 ft) (min.: M. L., unpubl. data; max.: Lauth 2000).
Family Gadidae — Cods
Arctogadus glacialis (Peters, 1872). Arctic Cod or Polar Cod. To 60 cm (23.6 in) TL (Coad 1995). Arctic
Ocean from Siberia to Greenland and northern Baffin Island (Cohen in Cohen et al. 1990, Endo in
Okamura et al. 1995); two records off Alaska in Beaufort Sea (Mecklenburg et al. 2002:291, 292). Pelagic
and probably also benthic (Jordan et al. 2003), typically far offshore beyond continental shelf under
drifting ice and in ice cracks (Cohen in Cohen et al. 1990), also in river mouths (Jordan et al. 2003),
in depths of 5–930 m (16–3,051 ft; Jordan et al. 2003). Molecular studies showed no genetic difference
between A. glacialis and A. borisovi Dryagin, 1932 (Møller et al. 2002), the so-called Toothed Cod.
Jordan et al. (2003) examined morphology of both forms and revised the genus, classifying A. borisovi
as a junior synonym of A. glacialis.
Boreogadus saida (Lepechin, 1774). Arctic Cod or Polar Cod. To 40 cm (15.7 in) TL, usually less than 25
cm (9.8 in; Cohen in Cohen et al. 1990). The largest we know of from our area is a specimen from the
Chukchi Sea off Cape Lisburne measuring 28.8 cm (11.3 in) TL (specimen provided by Dave Roseneau
to L. K. T., unpubl. data). Circumpolar in Arctic (Cohen in Cohen et al. 1990); Arctic Siberia to Cape
Olyutorskiy, western Bering Sea; Beaufort Sea (Frost and Lowry 1981) to Bristol Bay, southeastern
Bering Sea (Allen and Smith 1988). Brackish lagoons, river mouths (Morrow 1980), and ocean to depth
of 731 m (2,398 ft; Allen and Smith 1988). Additional citations in Mecklenburg et al. (2002).
Eleginus gracilis (Tilesius, 1810). Saffron Cod. To at least 55 cm (21.6 in) TL (Cohen in Cohen et al. 1990).
North Pacific and adjacent Arctic; Yellow Sea to East Siberian Sea and east to Dease Strait, western
Canada; Beaufort, Chukchi, and Bering seas and Gulf of Alaska to Sitka, southeastern Alaska (rare in
Gulf of Alaska; Mecklenburg et al. 2002). Brackish waters and river mouths to limit of tidal influence
(Morrow 1980), to continental shelf edge at depth of 200 m (656 ft; Cohen in Cohen et al. 1990).
Molecular evidence indicates Eleginus should be synonymized with Microgradus (Carr et al. 1999);
additional studies are needed for confirmation.
