The female lays thousands upon thousands of eggs, which are then fertilized and released by the male. The eggs are then laid on the riverbed where they grow over several days.

Many conservation programs have been established to help river sturgeon fish because of their cultural and ecological importance. These programs are designed to reduce overfishing, habitat destruction, and rebuild the fish populations. Many governments have also established fishing regulations such as size limits and seasonal bans to stop overfishing. There are also many non-profit organizations that support research and conservation efforts to save river sturgeon fish.
River sturgeon fish are a unique species that has been an integral part of riverine ecosystems for centuries. They are well-known for their unique appearance, gentle demeanor, and high quality caviar. They are now facing many threats, including habitat loss and overfishing that have resulted in a decline of their population. These fish require conservation efforts to ensure their survival.
