When the ambient pressure changes during a high or low front, or when the fish move to a different depth in the river, their bladder will expand or shrink. By jumping, they can gulp in air needed to maintain neutral buoyancy. The other reason they jump is to communicate with other sturgeon.
Why do my sturgeon jump out of pond?
Q: Why do sturgeons ‘jump’ or ‘bob’ around the edge of the pond? A: The sturgeons are looking for food.

Sturgeon can live to be more than 100 years old! The white sturgeon can grow 20 feet long and weigh more than 1,500 pounds!
How long can sturgeons live out of water?
They will quickly deteriorate within a few seconds of gill exposure to air, and will seldom survive past the 3- to 5-minute mark without access to water. Smaller fish, with more fragile gills, may be unsalvageable as opposed to larger fish with sturdier gills.

Why do fish come to the surface?
The reason they are at the surface trying to breathe is due to a lack of dissolved oxygen in the water. The low levels of oxygen are mainly due to a lack of aeration or poor water quality, which can then cause the fish to stress.
Can fishes feel pain?
“Fish do feel pain. It’s likely different from what humans feel, but it is still a kind of pain.” At the anatomical level, fish have neurons known as nociceptors, which detect potential harm, such as high temperatures, intense pressure, and caustic chemicals.
What makes fish jump in a lake?
High Ammonia Levels
If Ammonia levels are not monitored, they can quickly rise and become very dangerous. As they excrete waste into the pond, it creates Ammonia. These high Ammonia levels can result in burns to the fish’s gills which could explain why they are jumping.
