USGS Ecosystems Science for Food and Water Security
USGS science developed by the Ecosystems Mission Area helps ensure safe and abundant domestic food and water supplies, ensuring all Americans access to livelihoods and traditions that connect generations with each other and the outdoors and strengthen America’s self-reliance. USGS science is used by decision makers at all levels to understand how the quality of America’s food supply is directly...
Brook trout vulnerability to drought: eastern component of USGS national integrated ecohydrological research
There is a growing and urgent need to develop and implement innovative strategies to research, monitor, and manage freshwater resources as societal demands escalate simultaneously with climate-driven changes in water availability.
Enabling AI for citizen science in fish biology
Artificial Intelligence (AI) is revolutionizing ecology and conservation by enabling species recognition from photos and videos. Our project evaluates the capacity to expand AI for individual fish recognition for population assessment. The success of this effort would facilitate fisheries analysis at an unprecedented scale by engaging anglers and citizen scientists in imagery collection. This...
Webinar: Assessing the Impact of Future Climate and Introduced Species on Hawaiʻi's Aquatic Ecosystems
View this webinar to learn how a warming climate will have fundamental impacts on freshwater, a critical driver of tropical island ecosystems.
Chinook Salmon (Oncorhynchus tshawytscha) - KFFS
Species Studied - Chinook Salmon ( Oncorhynchus tshawytscha)
Puget Sound Fall Chinook Estuarine Utilization
The WFRC has partnered separately with both the Skagit River System Tribal Cooperative and the Nisqually Tribe to research the use of otoliths (calcium carbonate deposits beneath the brain used in hearing and balance that grow in proportion to the overall growth of the fish) as a tool in examination of Puget Sound Fall Chinook salmon life history.
Chinook Salmon (Oncorhynchus tshawytscha)
Species Studied - Chinook Salmon ( Oncorhynchus tshawytscha)
Bull Trout (Salvelinus confluentus)
Species Studied - Bull Trout ( Salvelinus confluentus)
Fish Passage Hydraulic Flume
Many existing upstream and downstream fish passage structure designs (fishways, culverts, screens, downstream bypasses, etc.) function poorly or only for a narrow range of species or environmental conditions. Resource agencies consistently seek new or improved designs that pass a broader range of species with high efficiency and reliability, under a wider range of hydraulic operating conditions...
Pesticides, Flame Retardants, and Mercury in Tissues from Columbia Basin Pacific Lamprey
Pesticides, flame retardants, and mercury were present in Pacific lampreys ( Entosphenus tridentatus) at levels that may be contributing to their overall decline in the Columbia River Basin.These findings are based on the largest available dataset of contaminants measured in lamprey tissues and lamprey habitats by the U.S. Geological Survey (USGS) and the Columbia River Inter-Tribal Fish...
