Blog: A deeper dive into thiamine deficiency
Thiamine (vitamin B1) deficiency complex (TDC) has become a widespread affliction in fisheries around the world. During the 2022 annual meeting of the American Fisheries Society, a special symposium on TDC included presentations from researchers describing findings addressing the root causes of thiamine deficiency. TDC is not isolated to California’s Chinook salmon (Oncorhynchus tshawytscha) it also occurs in lake trout (Salvelinus namaycush) in the Great Lakes, and Atlantic salmon (Salmo salar) in Europe and in the northeastern United States, among other important fisheries. However, this symposium was not the first time scientists came together to understand TDC, as Dr. Dale Honeyfield – professor emeritus at the U.S. Geological Survey (USGS) – spoke about meetings sponsored by the Great Lakes Fishery Commission during the mid-1990s.
