摘要: Abstract Factors affecting feeding and growth of early life stages the federally endangered pallid sturgeon ( Scaphirhynchus albus ) are not fully understood, owing to their scarcity in wild. In this study was we evaluated performance a combined foraging-bioenergetics model as tool for assessing age-0 Missouri River. laboratory, three size classes larvae (18–44 mm; 0.027–0.329 g) were grown 7 14 days under differing temperature (14–24 °C) prey density (0–9 Chironomidae larvae/d) regimes. After accounting effects water on fish activity, compared observed final weight, length, number consumed values generated from model. When confronted with an independent dataset, provided reliable estimates (within 13% observations) consumption, underscoring usefulness modeling approach evaluating dynamics larval when empirical data lacking.
