Sodium balance in adult atlantic salmon (Salmo salar L.) during migration into neutral and acid fresh water
International audience 1. In sea-water, adult salmon (S. salar) exchange an average of 12.6% of total body sodium/hr. 2. Following transfer to fresh water sodium uptake follows Michaelis-Menton kinetics. Fmax = 2.40 mmol Na/1 ECF/hr, Km = 0.26 mmol Na/1. The uptake system is fully activated immediat...
