We have been involved with testing and application of imaging sonar systems in fisheries studies since they first became available for use in 2000. We have extensive experience using Dual-frequency Identification Sonar (DIDSON) and Adaptive Resolution Imaging Sonar (ARIS) in a wide variety of investigations including for assessing fish passage, estimating escapement, evaluating fish behavior and characterizing fish-habitat relationships.
