Both sturgeons and paddlefish have been referred to as "primitive fishes" because their morphological characteristics have remained relatively unchanged since the earliest fossil record. The daily bag limit is one white sturgeon with a fork length of 44-50 inches.

[42] White sturgeon populations along the US west coast declined simultaneously under the pressure of commercial fishing and human encroachment. volume 1, 4th edition. While all Orthodox groups forbid the consumption of sturgeon, some conservative groups do allow it.

Single point barbless hooks are required for all sturgeon fishing. During that time, they are dependent on their yolk sacs for nourishment.

[41][43], By the turn of the century, commercial production of sturgeon caviar in the US and Canada had come to an end. John North, (971) 673-6029, [email protected], About Us | Fishing | Hunting | Wildlife Viewing | License / Regs | Conservation | Living with Wildlife | ODFW Outdoors | Workday Login, ODFW Home | Driving Directions | [32][35], The phylogeny of the Acipenseridae, as on the cladogram, shows that they have evolved from among the bony fishes. Regulatory protections and conservation efforts were put in place by state and federal resource agencies in the US and Canada, such as the 1998 US federal moratorium that closed all commercial fishing for Atlantic sturgeon. Sturgeon are recognizable for their elongated bodies, flattened rostra, distinctive scutes and barbels, and elongated upper tail lobes.

[67] The theological debate over its kosher status can be traced back to such 19th-century reformers as Aron Chorin, though its consumption was already common in European Jewish communities.

In the Pacific Ocean, they are found in the Amur River along the Russian-Chinese border, on Sakhalin Island, and some rivers in northeast China. [49][50][51] Some species of sturgeon are extinct, several are on the verge of extinction, including the Chinese sturgeon,[52] the highly prized beluga sturgeon,[53] and the Alabama sturgeon.

Exceptionally, both Huso species, the white sturgeon and the pallid sturgeon feed primarily on other fish as adults.

Multilingual illustrated guide to the world's commercial coldwater fish. Pp. [68], Sturgeons were declared to be a royal fish under a statute dating back to 1324 by King Edward II of England. Those requirements may or may not be met every year due to varying environmental conditions, such as the proper photoperiod in spring, clear water with shallow rock or gravel substrate, where the eggs can adhere, and proper water temperature and flow for oxygenation of the eggs.

[4][5] Sturgeons are native to subtropical, temperate and sub-Arctic rivers, lakes and coastlines of Eurasia and North America.[6]. On a global scale, one such organization is the World Sturgeon Conservation Society (WSCS) whose primary objectives include fostering the "conservation of sturgeon species and restoration of sturgeon stocks world-wide”, and supporting the "information exchange among all persons interested in sturgeons. The caviar was estimated to be worth around $2 million. Four species may now be extinct. [25] The electroreceptors are thought to be used in various behaviors such as feeding, mating and migration. Sturgeon is the common name for the 27 species of fish belonging to the family Acipenseridae.

Sturgeons are long-lived, late-maturing fishes with distinctive characteristics, such as a heterocercal caudal fin similar to those of sharks, and an elongated, spindle-like body that is smooth-skinned, scaleless, and armored with five lateral rows of bony plates called scutes.

[27] Another explanation is that it "simply feels good". [24], Many sturgeons leap completely out of the water,[26] usually making a loud splash which can be heard half a mile away on the surface and probably further under water. [41] As with the decline in sturgeon populations in the US and Canada, the same occurred with sturgeon populations in the Caspian Sea. Springer-Verlag, New York. Although their evolution has been remarkably slow, they are a highly evolved living fossil, and do not closely resemble their ancestral chondrosteans. 4034 Fairview Industrial Drive SE   ::   Salem, OR 97302   ::    Main Phone (503) 947-6000 or (800) 720-ODFW [6339] [19], No species is known to naturally occur south of the equator, though attempts at sturgeon aquaculture are being made in Uruguay, South Africa, and other places. Sturgeons are among the largest fish: some beluga (Huso huso) in the Caspian Sea reportedly attain over 5.5 m (18 ft) and 2000 kg[11] (4400 lb) while for kaluga (H. dauricus) in the Amur River, similar lengths and over 1,000 kg (2,200 lb) weights have been reported. [23] Sturgeons feed non-visually.
