Evaluation of the effectiveness of radio-telemetry methods to monitor passage routes of juvenile salmonids at Ice Harbor Dam, 1996

Radio-telemetry research has provided considerable knowledge on adult salmonid behavior. Recently, miniaturization of electronic components has led to construction of transmitters small enough for implantation in juvenile salmonids and has provided the means to monitor smolt behavior during downstream migration. The objective of this study was to determine the feasibility of monitoring all potential passage routes of juvenile salmonids through a hydroelectric dam. Ice Harbor Dam in the Snake River (RKm 15.6) was the study site. Contract no. E86-96-0096
