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


Start Date


This SSP project resulted in production of a thesis: Differences in oxygen consumption and critical oxygen levels of five stream fishes. Metabolic rate represents an integrated measure of a fish's physiology, particularly as it relates to stressors. A metric that is commonly used to determine the hypoxia tolerance of fishes is the determination of animal oxygen consumption rate (MO2), which is thought to reflect the ability of an organism to extract oxygen from the environment to maintain routine metabolic rate as dissolved oxygen (DO) decreases. We used respirometry to quantify the influence of two abiotic factors as potential stressors on stream fishes: temperature and dissolved oxygen. We determined standard oxygen consumption [...]
