Deep water demersal fish live beyond this edge, mostly down the continental slopes and along the continental rises which drop to the abyssal plains. This is the continental margin, constituting about 28% of the total oceanic area. [20] Other deep sea demersal fish can also be found around seamounts and islands.

Inhabitants of the demersal zone feed off the bottom or off other demersal fish. See also pelagic zone. Demersal fish – fish that live in the demersal zone. Examples are cod, flounder and snapper. Compared to pelagic fish, demersal fish contain little oil. See also bottom feeder. Demersal trawling – trawling on or near the bottom of a sea ...
Cod (pl.: cod) is the common name for the demersal fish genus Gadus, belonging to the family Gadidae. [1] Cod is also used as part of the common name for a number of other fish species, and one species that belongs to genus Gadus is commonly not called cod (Alaska pollock, Gadus chalcogrammus).
Yellowfin sole is fished commercially, primarily by demersal trawl fishing. Having recovered from high fishing rates in the 1960s and 1970s, it is currently not considered to be overfished, and the biomass of yellowfin sole in the Bering Sea is estimated to be high and stable, above its target level. Catch has averaged 94,000 tons from 1998 to ...
It is a demersal fish native to marine or brackish waters of the Northeast Atlantic, Baltic Sea and the Mediterranean Sea. It is an important food fish. [4] Turbot in the Black Sea were often included in this species, but are now generally regarded as separate - the Black Sea turbot or kalkan (S. maeoticus). [5]
The distinction between demersal species of fish and pelagic species is not always clear cut. The Atlantic cod (Gadus morhua) is a typical demersal fish, but can also be found in the open water column, and the Atlantic herring (Clupea harengus) is predominantly a pelagic species but forms large aggregations near the seabed when it spawns on banks of gravel.
