Tidewater Goby Survey

Tidewater Goby


March 2016 - September 2018


The goal of this research is the development of environmental DNA (eDNA) techniques and methods for monitoring endangered tidewater goby presence/absence to provide an innovative and improved set of tools for detecting tidewater goby in Caltrans project areas and perform specified surveys. The new eDNA techniques and methods will help develop a survey protocol that detects tidewater goby with higher confidence. Improved survey techniques will help Caltrans save money and avoid delays during maintenance and construction by reducing time spent in minimizing endangered species consultations to those situations where they are necessary.
