Adverse effects of mercury to fishes, in addition to those listed on reproduction and growth, have been documented at water concentrations of 0.88-5.0 xg/L enzyme disruption in brook trout (Salvelinus fontinalis) embryos immersed for 17 days in solutions containing 0.88 ig/L, as methylmercury decreased rate of intestinal transport of glucose, fructose, glycine, and tryptophan in the murrel (Channa punctatus) at 3.0 (xg Hg +/L for 30 days altered blood chemistry in striped bass (Morone saxatilis) at 5.0 xg Hg +/L in 60 days and decreased respiration in striped bass 30 days post-exposure after immersion for 30-120 days in 5.0 xg Hg +/L. In large-mouth bass, elevated liver metallothioneins are indicative of elevated muscle mercury concentrations, suggesting that mercury-induced metallothioneins may be useful biomarkers of mercury exposure.
