Biological Monitoring – Fish Data
Fish represent the top of the aquatic food chain and are important indicators of ecosystem health. Extensive knowledge of the habitat, life history, longevity, and mobility of native species provide insight into long-term and widespread effects of the physical and chemical alteration of water. Fish collection and habitat data are available on DEQ’s website.
