[5][6] Acipenser nudiventris typically feed on other animals near the benthos including: insect larvae, mollusks, crustaceans, and other smaller fish.

[8] Migration to freshwaters for deposition of eggs occurs during spring between the months of March and May, and fall between October and November.

[8] One of the most established populations is one in Lake Balkhash in Kazakhstan, well outside its natural range, where they were introduced in the 1930s for commercial purposes.

[5] A decline in the abundance of Acipenser nudiventris has been reported due to overfishing and damming, which have led to limitations placed on fishing for bastard sturgeon in areas such as the Ural River.

[8][9] In order to alleviate concerns with rapidly decreasing Acipenser nudiventris, an effort was made to raise these fish in captivity before releasing them back into rivers they once inhabited.
