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.
Altogether, the pelagic zone occupies 1,330 million km 3 (320 million mi 3) with a mean depth of 3.68 km (2.29 mi) and maximum depth of 11 km (6.8 mi). [2] [3] [4] Pelagic life decreases as depth increases. The pelagic zone contrasts with the benthic and demersal zones at the bottom of the sea. The benthic zone is the ecological region at the ...
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 ...
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.
The tiger rockfish is a large, heavy bodied species of rockfish [4] with a large mouth. [5] There are 13 robust spines and between 13 and 15 soft rays in the dorsal fin while the anal fin contains 3 spines and 6 or 7 soft rays. There are robust spines on the head and these are the nasal, preocular, supraocular, postocular, tympanic, coronal ...
These fish are not known for great battles or for large size, although the larger specimens may provide good sport. [11] According to the Oregon Department of Fisheries and Wildlife, the sport harvest of nearshore rockfish (such as quillback, copper and china rockfish) off the Oregon coast has been 6-12 metric tons annually between 2004 and 2009.
Pelagic larvae can disperse large distances, colonize new territory, and move away from habitats that has become overcrowded or otherwise unsuitable. A long pelagic larval phase can help a species to break its parasite cycles. Pelagic larvae avoid benthic predators. Dispersing as pelagic larvae can be risky.
