As adults, sturgeons have few predators. Their size and their scutes protect them from being eaten by many creatures. However, when they are in the ocean, they can be attacked by sea lampreys (an eel-like fish) and sharks. Sturgeon eggs and very young fish are often eaten by other fish.
While growing to reach massive sizes, White Sturgeon have never behaved aggressively toward humans. They actually have no teeth and feed by sucking prey through their ventral vacuum-like mouth that is directed downward on their heads to face below them.
Yes, sturgeons are safe to eat. However, the main reason why you can't always actually eat sturgeon is the rules surrounding their capture. In some areas throughout North America such as Florida and California, there are strict restrictions on species that can be caught and taken home.
Sturgeons are primarily benthic feeders, with a diet of shellfish, crustaceans, and small fish. Exceptionally, both Huso species, the white sturgeon and the pallid sturgeon feed primarily on other fish as adults.
As of today, two-thirds of sturgeon species are now critically endangered, and one species is completely extinct. One of the leading reasons why sturgeons are endangered is due to poaching. As part of the illegal food trade, sturgeon poaching for wildlife caviar and meat is a major threat to the species.
Can sturgeon bite? No, as sturgeon have no teeth. They feed by sucking in their food. Prey is detected by taste and touch by four sensitive barbells in front of the mouth, and by a system of sensors on the underside of their long, flat snout.
Caviar has been criticized and even banned in some jurisdictions for its extreme impact on wild sturgeons, which are the most endangered species group on earth. Sturgeons are intelligent and complex fishes who have lived on this planet for over 200 million years.

The Beluga Sturgeon (Huso huso) is the biggest freshwater fish in the world. The largest Beluga ever caught weighed 1,571 kg and was 7.2 m long. The Beluga is extremely long lived and females do not reach maturity until at least 15 years of age.
Lifespan: Lake Sturgeon are extremely long-lived; males may live up to 55 years and females have the potential of reaching 150! Shovelnose sturgeon can live up to 70 years in captivity and 30 in the wild.
Sturgeon has more vitamin A, vitamin B3, and iron; however, salmon has more selenium, vitamin B6, vitamin B1, vitamin B12, and vitamin B5. Salmon's daily need coverage for selenium is 46% more. Sturgeon has 4 times more vitamin A than salmon. Sturgeon has 875 IU of vitamin A, while salmon has 230 IU.
Abstract. Caviar, the roe of sturgeon, was one of Iran's major export items before the Islamic revolution of 1979. But the consumption of sturgeon was considered forbidden (haram) under Shiite law because under that law only fishes with scales (and their roe) can be eaten, whereas the sturgeon lacked scales.
It is illegal to totally or in part remove any sturgeon larger than 54 inches in fork length from the water; these must remain in the water at all times. When catch-and-release fishing, sturgeon must be returned to the water immediately unharmed.
According to IGFA records, the largest fish ever caught was a great white shark that weighed an unbelievable 2,664 pounds (1,208.389 kg.). Caught off the coast of Ceduna, Australia, in 1959, it took angler Alfred Dean just 50 minutes to win the fight against this one-ton shark.
Sturgeons are the most endangered species group on earth. These gentle giants have been around since the age of the dinosaurs, but are now on the brink of extinction due to overfishing, a flourishing illegal caviar trade and habitat loss.
Caviar farming, or sturgeon aquaculture, has emerged as a sustainable and ethical alternative to traditional methods. By nurturing sturgeon in controlled environments, caviar producers can harvest eggs without harming the fish or depleting wild populations.
When extracting fish roe from sturgeon, there are two main processes: the classic harvesting method and the "no-kill" harvesting method. The classic method kills the fish, while the humane method keeps the fish alive and extracts the roe through the vivace or c-section method.
To be considered caviar, the roe must come from sturgeon, or fish of the Acipenseridae family. The unfertilized sturgeon eggs are still considered roe until they're salt-cured, at which point it becomes a delicacy known as caviar.
Sturgeon do not have teeth! They suck up food like a vacuum with their protrusible mouth. After swallowing food whole, their muscular stomach crushes it into smaller pieces for digestion. Some prey that sturgeon eat are polychaetes (worms), mollusks, and crustaceans.
Early Morning: Sunrise to Mid-Morning. Why It Works: During the early hours, white sturgeon are more likely to be active and feeding. The low light conditions make them feel safer, encouraging them to move closer to feeding areas.
Capable of reaching lengths of 20 feet, White Sturgeon are the largest fish in in North America (but 10–12 feet is considered large by today's standards). Green Sturgeon are no size slouch either—they max out around 8 feet long but are more commonly in the 4–5 foot range.
Sturgeon's law is a saying that 90 % of anything is really bad. It was created by Theodore Sturgeon to defend science fiction from people who didn't like it. It is often quoted as “No doubt 90 % of science fiction is crap then again 90 % of anything is crap”.
The largest and oldest lake sturgeon grow to about 7 feet in length, weigh 200-300 pounds, and live to 150 years of age. Typically, adult lake sturgeon are about 4-6 feet long, weigh 30-80 pounds, and live to be 50-100 years old.
The largest sturgeon ever recorded was a Beluga sturgeon caught in the Volga estuary in 1827, measuring a whopping 7.2 meters (24 feet) and weighing over 1.5 tons (3,463 lbs)! With their armored bodies and ancient lineage, sturgeons are a true testament to nature's resilience.
