Exploration of AYK Chinook Salmon Egg Thiamine Levels as a Potential Mechanism Contributing to Recent Low Productivity Patterns
Chinook salmon in western Alaska have experienced declines in productivity and the mechanisms driving these declines are poorly understood. Thiamine (vitamin B1) deficiency has been responsible for declines in numerous salmonid populations and its prevalence in western Alaska Chinook salmon was inve...
