What are sturgeons predators?
Most predation of sturgeon happens during the egg stage. Sturgeon eggs are vulnerable to predation by larger benthic organisms such as crayfish, and small fish. Fingerling and small juvenile sturgeon can be predated by herons. By the time sturgeon reach 20 inches or more in length their primary predator is humans.
Why are pallid sturgeon important?

Are pallid sturgeon extinct?
The pallid sturgeon was listed as endangered in 1990 and recovery efforts include research to learn more about its life history and habitat requirements, artificial propagation to improve its numbers, habitat improvement and reducing mortality from commercial fishing.
What is the largest sturgeon ever caught?
The International Game Fish Association, the keeper of fishing world records, lists a 468-pound white sturgeon caught by Joey Pallotta III in Benicia, Calif., in July 1983 as the official world record.

Are sturgeons boneless?
Sturgeon is the main fish family used for caviar production. ... Males are typically harvested for meat which is almost boneless, as sturgeon are composed of mostly cartilage. Females are harvested at a later age in order to harvest the caviar.
Do sturgeon eat anchovies?
They are anadromous, meaning they start their life in fresh water and spend part in salt water, just like salmon. But unlike Pacific salmon, sturgeon do not die after they spawn. ... In their natural habitat, sturgeon feed on clams, mussels, crayfish, worms, lamprey, smelt, anchovies, shad, fish eggs and other dead fish.
What do sturgeon eat in ponds?
A: Sturgeons normally eat shrimps and snails which hide most of the day and come out at dawn/dusk so the sturgeon swim around looking for them.
Where do sturgeon lay their eggs?
Lake sturgeon migrate to shores of freshwater lakes in early summer for spawning. Female lay anywhere from two to three million eggs per season.
Are sturgeon bottom feeders?
