Which specific food item do Young-of-the-Year White Sturgeon consume after relying on the yolk sac?
Answer
*Corophium* species
After hatching and relying initially on their yolk sac for sustenance, White Sturgeon larvae transition to external feeding. Once they begin feeding, these young fish become relatively sedentary, allowing water currents to carry them toward suitable feeding grounds downstream. In these areas, they primarily consume small benthic invertebrates. The text specifically identifies species within the genus *Corophium* as the primary food source for these young-of-the-year fish as they establish themselves.
