Gas Bubble Trauma
Detailed Description
This is a photo of a fish with gas bubble trauma. For decades, scientists at the USGS Western Fisheries Research Center (WFRC) have worked alongside dam operators to monitor a lesser-known threat to fish in the Columbia and Snake rivers: gas bubble trauma.

First investigations on lamprey responses to elevated total dissolved gas exposure and risk of gas bubble trauma First investigations on lamprey responses to elevated total dissolved gas exposure and risk of gas bubble trauma
A flexible spill program in the federal Columbia River power system increased the total dissolved gas (TDG) water quality standards (i.e., the gas cap) from 120% to 125%. Spill is used to pass juvenile salmon (Oncorhynchus spp.) over dams, but it can generate elevated TDG, and exposed fish can develop gas bubble trauma (GBT) or experience mortality. Juvenile salmon are monitored for GBT...

Monitoring native nonsalmonids for the incidence of gas bubble trauma downstream of Snake and Columbia River dams during the spring spill season, 2022 Monitoring native nonsalmonids for the incidence of gas bubble trauma downstream of Snake and Columbia River dams during the spring spill season, 2022
In 2020, a new spill program was implemented to aid the downstream passage of juvenile salmonids at mainstem dams on the Snake and Columbia rivers. Under this program, the total dissolved gas (TDG) cap was increased to 125% and monitoring of native nonsalmonids for gas bubble trauma (GBT) became a requirement. The primary objective of this work was to measure the incidence and severity...

Progression and severity of gas bubble trauma in juvenile salmonids Progression and severity of gas bubble trauma in juvenile salmonids
We conducted laboratory experiments to assess the progression and to quantify the severity of signs of gas bubble trauma (GBT) in juvenile chinook salmon Oncorhynchus tshawytscha and steelhead Oncorhynchus mykiss exposed to different levels of total dissolved gas (TDG), and we attempted to relate these signs to the likelihood of mortality. When fish were exposed to 110% TDG for up to 22...
