Determinants of growth and survival of larval pallid sturgeon: a combined laboratory and field approach


September 2009 - December 2013


Since 1990, the pallid sturgeon (Scaphirhynchus albus) has been listed under the Endangered Species Act. Our research addresses knowledge gaps in the early life-history of the pallid sturgeon. Past research has found that a fundamental aspect of early life history of pallid sturgeon is larval drift. The lack of natural recruitment in this species requires a basic knowledge of the feeding and life-history attributes for larval and juvenile stages once larvae settle into nursery habitats. Thus, efforts to restore the pallid sturgeon must be augmented with a knowledge of their early life-history. To address these issues, we are conducting a combination of laboratory and in-situ experiments to identify prey selectivity, habitat preference, and factors affecting survival of larval pallid sturgeon
