The osmoregulatory abilities of Amphistichus argenfeus were examined following transfer from hypertonic to hypotonic sea‐water. Although some regulatory capacity was evidenced by an increase in glomerular filtration during acclimation to hypotonic sea‐water, the fish did not appear able to counter the tendency to lose electrolytes in this medium. When compared to a truly euryhaline species, such as Salmo gairdneri, A. argenteus possessed only a limited capacity to survive in a hypotonic environment.
