Reproduction of the Snake River Sturgeon

The Snake River sturgeon’s journey of procreation is a remarkable spectacle that has unfolded for centuries. Spawning season commences in the spring, when the river’s waters swell with the melting snow from the surrounding mountains. Led by an ancient instinct, mature sturgeon embark on an arduous migration upstream, seeking suitable spawning grounds.

Gravel beds nestled in shallow, well-oxygenated waters provide the ideal haven for the sturgeon’s precious offspring. With meticulous care, the female sturgeon uses her strong tail to construct a depression in the gravel, creating a secure and sheltered environment for her eggs.

Once the nest is prepared, the female releases a multitude of small, adhesive eggs into the gravel. The eggs are fertilized by the male sturgeon, who releases milt into the water, allowing it to permeate the gravel and reach the eggs.

Throughout the incubation period, the eggs remain protected within the gravel nests. The constant flow of water provides oxygen and nutrients to the developing embryos. After approximately two weeks, the eggs hatch into tiny larvae. These larvae remain in the gravel for several weeks, feeding on the abundant microorganisms present there.

As the larvae grow, they gradually emerge from the gravel and begin to feed independently. Their primary diet consists of small aquatic organisms, such as zooplankton and insects. Over time, the young sturgeon migrate downstream, eventually reaching the larger waters of the Snake River and its tributaries.
