Our fisheries researchers are world-class scientists. They conduct cutting-edge research to provide fisheries resource managers the scientific information they need to protect, restore, and enhance our Nation’s fisheries and their habitats.
Imperiled Species Research
Forty percent of all fish species in North America are at risk of extinction. USGS research is crucial to protect and manage at-risk species and healthy fish populations into the future.Learn More
Drought and Ecological Flows
As part of the USGS Fisheries program, ecological flows, or the relationships between quality, quantity, and timing of water flows and ecological response of aquatic biota and ecosystems; and related ecosystem services are being investigated.Find Out More

A bioenergetics evaluation of temperature‐dependent selection for the spawning phenology by Snake River fall Chinook salmon
High water temperatures can increase the energetic cost for salmon to migrate and spawn, which can be important for Snake River fall‐run Chinook salmon because they migrate great distances (>500 km) at a time when river temperatures (18–24°C) can be above their optimum temperatures (16.5°C). Average river temperatures and random...Plumb, John M.
Juvenile Chinook salmon and forage fish use of eelgrass habitats in a diked and channelized Puget Sound River Delta
Eelgrass Zostera marina can form extensive meadows on Puget Sound river deltas. The extent to which these meadows provide critical rearing habitat for local estuarine fishes, especially out‐migrating juvenile salmon, is not well understood. Further, delta eelgrass has been impacted by diking and river channelization with unknown...Rubin, Stephen P.; Hayes, Michael C.; Grossman, Eric E.
Insight into infectious hematopoietic necrosis virus (IHNV) in Chinese rainbow trout aquaculture from virus isolated from 7 provinces in 2010–2014
The aquatic rhabdovirus infectious hematopoietic necrosis virus (IHNV) currently causes substantial fish losses in Chinese coldwater aquaculture. While IHNV was first reported in China in 1985 and has since undergone considerable spread, little is known about the underlying epidemiological patterns like introduction sources and...Jia, Peng; Breyta, Rachel B.; Li, Qing; Qian, Xu; Wu, Bing; Zheng, Wei; Wen, Zhiqing; Liu, Ying; Kurath, Gael; Hua, Qunyi; Jin, Ningyi; Liu, Hong
