Calibration of the Stream Salmonid Simulator (S3) model to estimate annual survival, movement, and food consumption by juvenile Chinook salmon (Oncorhynchus tshawytscha) in the restoration reach of the Trinity River, California, 2006–18 Calibration of the Stream Salmonid Simulator (S3) model to estimate annual survival, movement, and food consumption by juvenile Chinook salmon (Oncorhynchus tshawytscha) in the restoration reach of the Trinity River, California, 2006–18

Executive SummaryThe Trinity River is managed in two sections: (1) from the upper 64-kilometer “restoration reach” downstream from Lewiston Dam to the confluence with the North Fork Trinity River, and (2) the 120-kilometer lower Trinity River downstream from the restoration reach. The Stream Salmonid Simulator (S3) has been previously applied to these reaches and the Klamath River. To...

Behavioral responses of Silver Carp to underwater acoustic deterrent sounds Behavioral responses of Silver Carp to underwater acoustic deterrent sounds

ObjectiveInvasive carps continue to spread across the Mississippi River basin, posing significant ecological risk. Identifying technologies to slow their dispersal is critical. The use of sound has been proposed as a method to modify the behavior of Silver Carp Hypophthalmichthys molitrix, offering a nonstructural deterrent strategy.MethodsSilver Carp implanted with acoustic transmitters...

Survival, travel time, and use of migration routes by juvenile steelhead in a modified river estuary Survival, travel time, and use of migration routes by juvenile steelhead in a modified river estuary

Greater understanding of the survival, travel time, and spatial distribution of juvenile salmonids among migration routes between their natal streams and the ocean is critical to the recovery of these threatened species. In the Sacramento–San Joaquin River Delta (Delta), a highly modified estuary in central California, USA, there is a critical need to evaluate how water management (e.g...

USGS Research on 6PPD-quinone: Where the Rubber Meets the Road

Stormwater and road runoff are recognized forms of pollution that can contain chemicals harmful to fish and other aquatic animals. This includes 6PPD-quinone, the oxidized form of the chemical compound 6PPD that is used to prevent tires from degrading and cracking, ensuring driver safety. As 6PPD-quinone sheds from tires during normal wear it can enter streams in stormwater runoff.
