Cod is a popular food fish with a mild flavor, low fat content, and a dense white flesh that flakes easily.
Cod livers are processed to make cod liver oil, an important source of Vitamin A, Vitamin D and omega-3 fatty acids (EPA and DHA).

 Feeding of Mesopelagic Fish
The Atlantic cod is the key fish predator in the southern Gulf of St. Lawrence (Majowski and Waiwood, 1980).
Cod are described as voracious benthic feeders by Scott and Scott (1988), consuming a diverse diet, fish being a large diet component with the type varying by locality.
Their analysis revealed that the percentage of herring in cod diet was less than 1% when the herring abundance was low, however, at peak population, herring never contributed more than 14% to cod diet.

Pacific cod are oviparous and have external fertilization (Hart 1973, NOAA 1990).

 Cod starvation means no seal cull justification
Two troubling facts, that Atlantic cod are not only now extremely few in number, but that the few remaining cod and other bottom fish are unusually poorly nourished, have been a great source of scientific mystery.
The nature of the disconnect between cod and herring, the “benthic pelagic decoupling” that DFO scientists are struggling to understand on the Eastern Scotian Shelf, cannot be clearly delineated and explicitly stated, because this is not a real possibility for these fish species that have long co-existed in the sea.
Therefore, DFO's hypothesis that a great biomass of pelagic fish - largely herring, capelin, and sand lance - is currently causing the starvation of bottom fish by preventing the flux of food to bottom, seems to be contradicted by known aspects of the biology of these "pelagic" fish species.

Vessel owners in the demersal fisheries now were also beginning to realise that the cod stock, the mainstay of the Icelandic economy, accounting for about 35% of the total value of marine products, was in danger of collapse similar to that of the herring stock a decade earlier, still fresh in their memory.
The sharp reductions in TACs for cod in 1994-6 are noteworthy.
The pelagic species of fish in Icelandic waters, herring and capelin, are rather similar to the animals of the Southwest plains described by Demsetz: clearly, any territorial rights to those two fish stocks would have been unfeasible.

 A global assessment of fisheries bycatch and discards   (Site not responding. Last check: 2007-09-29)
On a weight basis, the cod jig, sablefish pot, and rock sole trawl fisheries all discard more tonnage and numbers of fish than they retain, but the cod jig and sablefish pot fisheries are very small and contribute little to total regional discards.
Discard-induced mortalities for cod, Atka mackerel, sablefish, and Pacific Ocean perch are also relatively small in relation to mortalities resulting from landings of these species, and the increase in total instantaneous mortality is substantially less than one for each of these species.
Although the pelagic trawl fisheries take and discard a large number of species, the overall catch of the target species is very high while the quantity of discards is very low.

Saffron cod are present and abundant in the nearshore shallow waters of the Chukchi Sea in June and July, as is indicated by their importance in the diets of seals and belukha whales at Shishmaref and Eschscholtz Bay at that time.
Large concentrations of saffron cod were encountered from September through October 1976 in depths of 0 to 25 m in Norton Sound, the northeast Bering Sea, and the southern Chukchi Sea.
It appears that in the colder, arctic waters of the Chukchi and Beaufort seas, saffron cod are less abundant and are replaced by arctic cod in the diets of marine mammals.

This difference reflects remarkably high prerecruit survival of cod in the earlier period of low abundance rather than unusually poor survival in the 1990s.
These pelagic fishes are potential predators or competitors of the early life history stages of cod.
This is consistent with the recent suggestion that the success of large predatory fishes may depend on ''cultivation'' effects in which the adults crop down forage fishes that are predators or competitors of their young.

Continental shelves are an oasis in the ocean for plants and animals due to the abundance of sunlight, shallow waters, and nutrient packed sediment that washes in from rivers, wave action, and, in some areas, upwelling.
In addition to the vast amount of benthic life, the continental shelf is home to a variety of species such as tuna, menhaden, mackerel, and cod.
People have depended on the continental shelf for thousands of years to provide 90% of the fisheries production in the world and, more recently, for petroleum.
