Project: The Effects of Drought on Delta Smelt Vital Rates

Description: This Project is necessary to obtain a better understanding of the effects of drought and management's response to drought on the Delta Smelt in order to avoid extinction. This study will test predication from other models to evaluate the impact of drought and management measures on Delta Smelt responses in terms of growth, phenotype diversity and survival during the spring and summer, when drought impacts are greatest.

Reference Number: 3600BP1696005

Implemented By: Regents of the University of California

Objective: Objectives are to 1) model existing date on distribution and abundance from Interagency Ecological Program (IEP) monitoring data to estimate survival during the spring and early summer; 2) analyze archived otoliths from IEP Gear Efficiency Special Studies collected during the drought to bolster the analysis of vital rates for years classes with small sample sizes; 3) model survival, growth and function of environment drivers and; 4) experimentally test additional isotope markers in archived otoliths, tissues, and water samples to identify residence in tidal wetland habitats.
