Explanation:
Sturgeon are an anadromous fish species that inhabit rivers, estuaries and the ocean at
various stages during their life cycle—and their lifecycle is a long one. Adults can live up to 80
years. After spending up to 3 years in their natal rivers as juveniles, they travel into the oceans
until they reach sexual maturity. This may take another 8-20 years, depending on the sex of the
fish (females usually take longer to reach sexual maturity) and latitude (sturgeon in the northern
rivers generally take longer to reach sexual maturity).
Spawning typically occurs in the in the springtime. Both sexes swim back up their natal
rivers to the spawning grounds. Females lay their eggs, which are sticky, and attach to the
river’s gravel bottom—larger females have been known to lay 800,000 to 3.5 million eggs. The
males then fertilize the eggs with milt. The adults leave the eggs to the mercy of the river and
their well chosen spawning grounds. Of that egg mass, only 10% will survive to reproduce in
the natal river again. The rest die due to predation, water pollution or a menagerie of other
causes.
