The Effect of Dietary Methylmercury on Na+, K+, -ATPase Activity and Growth in Fall-run Chinook Salmon (O. Tshawytscha)

Abstract

Hatchery reared Chinook salmon from California's Central Valley were fed for 67 days (Apr-Jun, 2008) on fish pellets mixed with either 0, 1, 3, or 5 µg•g-1 methylmercury hydroxide. Weight, fork length, condition factor, and Na + ,K +-ATPase measurements were determined every two weeks and a 96-h seawater challenge was conducted at the conclusion of the experiment. Results from two-way ANOVA, with treatment and date as independent variables,
