  • Ambient Fish Community Monitoring

    Fish are an important component of aquatic life in rivers and streams in Connecticut. The DEEP Water Monitoring group therefore uses fish as one of three biological communities to evaluate the health of waterbodies in Connecticut. (The other two biological communities include benthic macroinvertebrates and diatoms.) Fish have the ability to move within a reach to find better water quality, but they can only do so if there is adequate water present and no barriers to their movement such as dams. Fish are therefore good ‘indicators’ of problems related to water quantity and habitat connectivity. Fish are more sensitive to changes in the amount of water in a stream than other biological communities such as benthic macroinvertebrates, and a fish community with very limited fish can often be a signal of flow-related water quality impairments.
