      Juvenile lake trout were exposed to ambient free (un-ionized) ammonia concentrations of 0, 99, and μg NH 3 N 1 −1 for 60 days and fed one of two diets which were similar in energy concentration. Diet did not influence food intake at ammonia concentrations of 0, 99 and μg NH 3 N 1 − intake was unaffected by ammonia concentrations of 0 and 99 μg NH 3 N 1 −1 and was Thomas S () Changes in blood acid-base balance in trout (Salmo gairdneri R.) following exposure to combined hypoxia and hypercapnia.

    Carbonic anhydrase (CA) is the zinc metalloenzyme that catalyses the reversible reactions of CO2 with water. CA plays a crucial role in systemic acid–base regulation in fish by providing acid–base equivalents for exchange with the environment.

    A model is presented that provides guidelines to the identification of key experimental variables influencing proton balance and intracellular pH in vertebrate white muscle. We have drawn on data from the literature on rainbow trout (Oncorhynchus mykiss) in an attempt to quantify the influence of metabolic, ionic and transport components of Conducted a series of NSERC supported research projects on acid-base regulation, lactate and ammonia transport, and gas exchange in rainbow trout.
