Dissolved Oxygen Requirements for Freshwater Mussels Phase 1: Development of Test Systems and Experimental Protocols.


March 2008 - February 2010


The objectives of this pilot study (Phase I) are to:
1) Construct a gas-stripping system based on the Barnhart (1995) design to control DO levels.
2) Design a system to expose adult and juvenile mussels to DO treatments under semi-natural conditions.
3) Identify dependent variables (biomarkers) that are indicative of stress under low DO levels.
4) Determine the feasibility of maintaining low DO levels (1 - 3 mg/L) for extended exposures (weeks).
5) Develop a standard protocol to maintain and monitor DO treatments.
