This allows the tomcod
to survive, "but they still accumulate PCBs in their bodies and pass them on to whatever eats them," Hahn said.
Of the total of 21 extensively coastal species, 12 forms (i.e., the shortnose sturgeon, Atlantic sturgeon, American eel, blueback herring, hickory shad, alewife, American shad, rainbow smelt, Atlantic tomcod
, white perch, striped bass; and white catfish, Figure 43) are or have been commercially and/or recreationally important, primarily as food for humans.

Life history characteristics of Atlantic tomcod
. Atlantic tomcod
, Microgadus tomcod
, is a common anadromous species in many estuaries along the Atlantic Coast of North America from the Hudson River to Labrador, Canada (Bigelow and Schroeder 1953).
Examples include mummichog (91% of the total 1987 catch), white perch (1.4%), Atlantic silverside (2.6%), gizzard shad (0.2%), striped killifish (0.2%), striped bass (0.1%), and Atlantic tomcod
(0.6% during 1987, none collected during the current study).
During a flood, the water brings the tomcod
farther into the rivers.
Primarily marine species (northern anchovy, whitebait smelt, Pacific sardine, lingcod [Ophiodon elongatus], and Pacific tomcod
[Microgadus proximus]) were caught less consistently in the estuary, likely a reflection of seasonal patterns of estuarine use, offshore abundances, and whether conditions in the Columbia River estuary were favorable for occupation (Bottom and Jones, 1990).
There were many species of fish that were unique to SAG including the American eel (Anguilla rostrata), oyster toadfish (Opsanus tau), rock gunnel (Pholis gunnellus), and Atlantic tomcod
from the Hudson have 100-fold higher levels of PCBs than fish caught in cleaner rivers," he says.
