The sturgeon also feed on crustaceans, worms, and small fish (Carlson et al. 1985;Held 1969). As a result of bottom feeding, it is a host to the glochidia (larvae) of several species of freshwater mollusc, including Quadrula pustulosa (pimpleback), Obovaria olivaria (hickorynut) and Lampsilis teres (yellow sandshell). It is the only known host ...

Fish is a more important dietary staple for pallid sturgeon than it is for shovelnose sturgeon. [34] In one study comparing dietary tendencies between adult shovelnose sturgeon and immature pallid sturgeon, the pallid sturgeon was found to consume far greater numbers of small fish such as cyprinids (minnows).

The Amu Darya sturgeon feeds on small fish and aquatic insect larvae, with large individuals being mostly piscivorous. [1] [5]Studies in the 1960s and 1970s showed that Amu Darya sturgeon reach maturity when 5–8 years old (slightly later in females than males), but in the 1990s the youngest mature individuals only were 4 years old, possibly due to environmental changes in their habitat.
