Sturgeon can generally last for about 5-10 hours without water. They are fish and breathe with gills. If you leave the water, you will die in a short time. But how long they can stay away from water depends on their living environment. If they live in a humid environment after leaving water and someone sprays them regularly to keep them moist, they can stay on for a longer time, about 10 hours. If they live in a relatively dry environment after leaving the water, they will die if they persist for up to 5 hours. Some sturgeons may die after leaving the water for 2 hours.

How long can sturgeon live without oxygen depends on the water body in which they live. If the water body in which they live is large and the circulating filtration system has been installed, it can last for 3-4 days without oxygen. If they live in a small water body, they will die if they persist for 1-2 days at most without oxygen.

Sturgeon is a kind of fish with high oxygen consumption, which needs more oxygen to survive normally. If they can't be continuously oxygenated during breeding, they are likely to die of lack of oxygen.
