… As research assistants in a nationwide study — created in collaboration with experts from the UC Davis School of Education and Center for Watershed Sciences — high schoolers worked with scholars from 2020 to 2025 to collect the data needed to determine the cause of rising TDC [Thiamine Deficiency Complex] rates. Together, they monitored hundreds of spawning salmon for early signs of thiamine deficiency, most notably, swimming in spinning patterns. Researchers published the final study in July 2025, identifying anchovy-dominated diets as the cause of TDC. With a recent and ongoing decline in oceanic biodiversity, salmon are primarily consuming anchovies.
