Project: Effects of Multiple Environmental Stressors on Ecological Performance of Early Life Stage Sturgeon

Description: The purpose of this Project is to investigate the effects contaminants in early life stages of California sturgeon, under current and future climate conditions and water operation regimes. Funding for this Project will be used to obtain information critical to inform management strategies for conservation of sturgeon, as these types of data can be used to improve conceptual models, to identify key threats to recruitment to adult life stages, and to predict population productivity under a range of environmental conditions or management decisions.

Reference Number: 3600BQ1996038

Implemented By: Regents of the University of California, Davis

Objective: Objective 1. Procurement of experimental animals. White Sturgeon sourced from commercial hatchery fertilization and hatching of eggs, obtained and transported for study at 1-day post hatch. Green Sturgeon obtained through ongoing management of UC Davis captive broodstock, including monitoring for maturation, adjusting water temperature and turbidity, hormone injection, 24-hour spawn, and continuous egg collection. Objective 2. To assess developmental, physiological, and behavioral impacts of larval exposure of White Sturgeon and Green Sturgeon to lipophilic pesticides commonly found in the Delta and its tributaries at multiple temperatures. Objective 3. To evaluate ecologically relevant carryover effects in juvenile White Sturgeon and Green Sturgeon after larval exposure to multiple stressors (e.g., altered metabolic rates, reduced swimming capacity, reduced foraging efficiency).
