We hypothesized that the skin acts as an extrabranchial route for ammonia excretion in adult rainbow trout (Oncorhynchus mykiss) following high environmental ammonia (HEA) exposure. Trunks of control or HEA‐exposed trout were perfused with saline containing 0 or 1 mmol l−1 NH4+. Cutaneous ammonia excretion rates increased 2.5‐fold following HEA exposure, however there was no difference in rates between trunks perfused with 0 or 1 mmol l−1 NH4+. The skin is therefore capable of excreting its own ammonia load, but it does not clear circulating ammonia from the plasma. [ABSTRACT FROM AUTHOR] |
