Small halibut catches are reported in coastal Washington, Oregon, and California. Pacific halibut is broken up into 10 regularity management areas. Halibut are demersal, living on or near the bottom of the water and prefer water temperatures ranging from 3 to 8 °C (37.4 to 46.4 °F). Pacific halibut belong to the family Pleuronectidae.
T-S diagram of a station in the North Pacific. In oceanography, temperature-salinity diagrams, sometimes called T-S diagrams, are used to identify water masses.In a T-S diagram, rather than plotting each water property as a separate "profile," with pressure or depth as the vertical coordinate, potential temperature (on the vertical axis) is plotted versus salinity (on the horizontal axis).
The halibut is among the largest teleost (bony) fish in the world, and is a threatened species owing to a slow rate of growth and overfishing. [3] [4] Halibut are strong swimmers and are able to migrate long distances. Halibut size is not age-specific, but rather tends to follow a cycle related to halibut (and therefore food) abundance.

A fish that closely resembles the California halibut is the Pacific halibut (Hippoglossus stenolepis), which is a larger species found in the northern Pacific Ocean. While the Pacific halibut has a similar flat body shape, it is generally larger and can reach 300 pounds (140 kg), and can be distinguished by its slightly different coloration and ...
Ocean temperature as a term applies to the temperature in the ocean at any depth. It can also apply specifically to the ocean temperatures that are not near the surface. In this case it is synonymous with deep ocean temperature). It is clear that the oceans are warming as a result of climate change and this rate of warming is increasing.
The olive flounder (Paralichthys olivaceus), bastard halibut or Korean halibut is a temperate marine species of large-tooth flounder native to the North-western Pacific Ocean. It is the highest valued finfish in the world, known to be excellent for aquaculture due to a rapid growth rate and popularity in Korea .
The Greenland halibut is a cold-water species found at depths from near the surface to 2,200 m (7,200 ft), but mainly between 500 and 1,000 m (1,600 and 3,300 ft). [2] It is mainly found in waters with temperatures from 1 to 4 °C (34–39 °F), but has also been observed at subzero temperatures down to −2.1 °C (28.2 °F).
