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 .
Pacific ocean perch larvae are pelagic and drift with the current. Oceanic conditions may sometimes cause advection to suboptimal areas [ 9 ] resulting in high recruitment variability. However, larval studies of rockfish have been hindered by difficulties in species identification since many larval rockfish species share the same morphological ...
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.

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.
Starry rockfish are viviparous and the larvae and juveniles are pelagic. [1] The adults are sedentary and remain in the same area of seabed all their lives. They are predators which prey on fish, krill, octopus, and other marine invertebrates. Females can produce as many as 225,000 eggs in a year. This species may live for up to 32 years. [5]
The widow rockfish occurs from Todos Santos Bay, Baja California, to Albatross Bank, in the Gulf of Alaska. [1] Adult widow rockfishes are most abundant from British Columbia to northern California. [6] This is a pelagic-neritic fish which is found at depths between 0 and 549 m (0 and 1,801 ft). [1]
