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.

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 ...
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).
Fish stocks are subpopulations of a particular species of fish, for which intrinsic parameters (growth, recruitment, mortality and fishing mortality) are traditionally regarded as the significant factors determining the stock's population dynamics, while extrinsic factors (immigration and emigration) are traditionally ignored. Stocks fished ...
Experts refer to the temperature further below the surface as ocean temperature or deep ocean temperature. Ocean temperatures more than 20 metres below the surface vary by region and time. They contribute to variations in ocean heat content and ocean stratification. [11] The increase of both ocean surface temperature and deeper ocean ...
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. [1]
