Fish out of breath: Assessing, developing, and validating physiological bioindicators of hypoxia across the Delta
Description / purpose
This proposal seeks to generate two management tools to optimize ongoing conservation efforts (e.g. wetland restoration, fish supplementation) by accomplishing the following 4 objectives:
Objective 1) use controlled laboratory experiments to identify temperature-dependent hypoxia tolerance data (Pcrit) for ChinookSalmon smolts and juvenile Delta Smelt.
Objective 2) compile existing temperature and DO monitoring data across the SFE.
Objective 3) generate metabolic indices using the newly-generated physiological data (Obj. 1) and existing environmentalinformation (Obj. 2) to examine spatial and temporal patterns in metabolic stress for each species.
Objective 4) explore and develop an otolith-based bioindicator to identify past hypoxia exposure.
