On several of the Columbia River and tributary dams, in order to augment the data from ladder fish counting windows, fish are diverted into off-ladder collection facilities to get additional fish specific data. This, however, usually involves an interruption in upstream migration, temporary holding, the use of anesthetics and manual handling. In this session we will describe an automated system that can be used in these environments to collect more accurate counts, fish measurements and other data at the fish passage structure, while minimizing or eliminating stress and delay normally associated with fish handling.
