AbstractDuring summer 2025, we collected and tagged fish as part of a multiyear research project to monitor the migrational behavior and survival of wild juvenile spring/summer Chinook salmon in the Snake River Basin. Each study year, we collect wild Chinook parr in natal tributaries, implant them with passive integrated transponder (PIT) tags, and release them near their respective collection sites. In this report, we present data on fish collection and tagging efforts during July and August 2025. Detection data will be collected from these tagged fish as they begin migration during spring 2026. These data and the respective analyses will be presented in our 2026 Survival and Timing report. • During July and August 2025, we collected a total of 6,879 wild Chinook salmon parr from 7 Idaho sample locations. Of the parr collected, 5,429 were PIT tagged and released. • Of all fish collected, we observed an overall average length of 67 mm and average weight of 3.8 g. • We observed a mortality rate
