Project: Quantifying Genetic and Epigenetic Variation in Delta Smelt that may Enable Adaptation to Future Environments

Description: The purpose of this project is to investigate evidence that the hatchery environment is causing divergence in fitness between wild and hatchery Delta Smelt, and this correlates with divergence in thermal physiology between wild and hatchery fish. Funding for this Project will be used to further knowledge about the ability of Delta Smelt to adapt to future environments and relates to a key goal of climate research to predict and characterize species vulnerabilities to future environments.

Reference Number: 3600BQ1996041

Implemented By: Regents of the University of California, Davis

Objective: Question 1: Does Delta Smelt harbor genetic variation that may enable adaptation to future environments? • Objective 1: Measure additive genetic variation for thermal performance. • Objective 2: Identify and estimate the number of loci (and their effect size) that contribute to phenotypic variation in thermal performance. Question 2: Are phenotypic changes caused by hatchery rearing caused by hatchery-induced epigenetic changes? • Objective 3: Test whether thermal rearing environment causes epigenetic change in Delta Smelt.
