None supplied. Introduction: In 1983, the National Marine Fisheries Service (NMFS) began a multiyear cooperative research program with the Bonneville Power Administration (BPA) to evaluate a new miniaturized identification system that could be used with salmonids. The system is referred to as the passive-integrated-transponder (PIT) tagging and interrogation system. The program has focused on determining the effects of PIT tags on juvenile and adult salmonids, as well as the development and evaluation of tagging and interrogation methods. Earlier results of the program have been reported in annual reports and journal articles cited in this report. This report covers the work performed from 1990 through 1993. For convenience, the report is divided into three sections: (1) Interrogation and separation systems at Columbia River Basin dams, (2) Systems development and evaluation, and (3) Information and technology transfer.
