Growth inhibition of Siberian sturgeon (Acipenser baerii) from dietary and waterborne fluoride

As part of a recent study, growth trials were conducted to evaluate effects of dietary and waterborne fluoride ions (F) on juvenile Siberian sturgeon (Acipenser baerii). In 12-week dietary exposure experiments, growth was inhibited by diets with 710.2 or 1478.3 mg F/kg, but not with 162.6 or 360.8 mg F/kg compared to the control (75.2 mg F/kg). In 90-day waterborne exposure experiments, growth was inhibited at 7.8, 18.7, and 51.8 mg F/L but not at 3.1 mg F/L compared to the control at 0.26 mg F/L. These findings indicate that F can cause adverse effects on the growth of Siberian sturgeon.
