A school of large pelagic predator fish (bluefin trevally) sizing up a school of small pelagic prey fish . Pelagic fish live in the pelagic zone of ocean or lake waters—being neither close to the bottom nor near the shore—in contrast with demersal fish that live on or near the bottom, and reef fish that are associated with coral reefs.

The canary rockfish (Sebastes pinniger), also known as the orange rockfish, is a species of marine ray-finned fish belonging to the subfamily Sebastinae, the rockfishes, part of the family Scorpaenidae. It is native to the waters of the Pacific Ocean off western North America.
Black rockfish are pelagic, that is, they occur on the continental shelf. Like other pelagic fish, they spend most of their time amid the water columns and are generally associated with rougher terra. This can make it somewhat inconvenient for commercial fisheries, which are often situated in nearshore, shallow water, and rocky areas .
The tiger rockfish is a solitary and territorial species which defends a shelter, usually a crevice in rocky areas. The juveniles are pelagic. This species can rapidly change color when alarmed or when the light changes. [1] This species is a generalist and is dependent on the currents to bring food to its home range.
[4] [5] [6] Immature yellowmouth rockfish are pelagic for up to one year. [4] During the pelagic stage, immature yellowmouth rockfish larvae mature into juveniles, and then into adults. [ 4 ] Juvenile yellowmouth rockfish are vulnerable to predation by other fish, such as Pacific Hake and Chinook Salmon , as well as by seabirds. [ 4 ]
A peaceful fish that should be kept alongside similarly non-aggressive tank mates. Also known as white-spotted goby, brown-barred goby, bullet goby; scientific name amblygobius phalaena. Maximum ...
They can be contrasted with pelagic fish, which live and feed away from the bottom in the open water column. Demersal fish fillets contain little fish oil (one to four per cent), whereas pelagic fish can contain up to 30 per cent. [not verified in body]
Rockfish is a common term for several species of fish, referring to their tendency to hide among rocks. The name rockfish is used for many kinds of fish used for food. [ 1 ] This common name belongs to several groups that are not closely related, and can be arbitrary.
