Sculpin with Gas Bubble Trauma

Since the early 1990s, WFRC has supported state and federal agencies by providing regular assessments of gas bubble trauma in salmon. But salmon aren’t the only fish affected. In 2020, scientists at the Cook lab began monitoring GBT in resident species like sculpin, northern pikeminnow, and three-spined stickleback. These fish offer year-round insights into river conditions and help fill gaps in areas where salmon may not be present.
