Environmentally exposed adult tomcod
collected from the Hudson River and immediately sacrificed exhibited significantly higher expression of hepatic CYP1A mRNA expression than did tomcod
from four cleaner rivers (Kreamer et al.
However, at least two species of fish, the American eel (Anguilla rostrata) and the Atlantic tomcod
) are repeatedly collected under piers (Stoecker et al, 1992).
Prey in the inland waters included Pacific whiting (Puget Sound stock), Pacific tomcod
, plainfin midshipman, Pacific herring, market squid, shiner perch, sculpins, walleye pollock, sole, and sand lance (NMFS, 1997a).
In Norton Bay, there are several runs of salmon of different species, herring (Clupea pallasi), tomcod
(Eleginus gracilis), flounder (Liopsetta glacialis, Platichthys stellatus), smelt (Osmerus mordax), sculpins (Cottus spp.
In the Kenai River, tomcod
arrive in February and are present until the end of summer.
Their account of the prey species of belugas does not include a detailed description of the Bering and Chukchi Seas, but the species reported eaten by belugas in the Sea of Okhotsk include tomcod
, arctic char, salmon, herring, and others, as well as invertebrates.
Other important contributors to regional dissimilarity were adult Chinook salmon, jack mackerel, and Pacific saury (Cololabis saira) (all more strongly associated with the NC), and Pacific tomcod
(Microgadus proximus), surf smelt, and Pacific butterfish (all more strongly associated with the GF).

): a study in the lower Hudson River estuary.
Furthermore, species that were associated with both 80 and 160 m included large spiny dogfish, and quillback rockfish (Sebastes maliger), brown rockfish (Sebastes auriculatus), blackbelly eelpout (Lycodes pacificus), Pacific tomcod
(Microgadus proximus), walleye pollock (Theragra chalcogramma), shiner perch (Cymatogaster aggregate), pile perch (Rhacochilus vacca), black tip poacher (Xeneretmus latifrons), slender sole (Lyopsetta exilis), and plainfin midshipman (Porichthys notatus; Fig.
In two 10-day field experiments conducted during May and June 1998,1 investigated the effect of a large municipal pier on the growth of young-of-the-year Atlantic tomcod
) in the lower Hudson River estuary.
The most abundant larvae, in descending order, were northern anchovy, English sole (Parophrys vetulus), sand sole (Psettichthys melanostictus), rex sole (Glyptocephalus zachirus), and Pacific tomcod
(Microgadus proximus) (Fig.
