Dual frequency identification sonar (DIDSON) has been used to estimate chinook and sockeye salmon escapements in Alaska with great success. DIDSON is a multi-beam sonar that produces near video quality images in turbid water or low light conditions, allowing the user to determine fish passage, size, and direction of :// This banner text can have markup.. web; books; video; audio; software; images; Toggle

North Pacific basin-scale The widespread occurrence of diel vertical migration behavior in pelagic aquatic organisms suggests that there is a selective advantage of the behavior compared to a static vertical depth distribution in the water column. Juvenile sockeye salmon (Oncorhynchus nerka) are active diel vertical migrators within pelagic lacustrine habitats, usually migrating over vertical distances covering tens of Inputs from dairy operations, including areas of active animal use and waste application fields, are estimated to contribute % of the NBR TP load and % of the overall TP load to Lake Waco.
