Brook trout were exposed to a subacute acid (pH 4.9) environment for a 28 day period in a gravity-flow proportional diluter system. Hematocrit and hemoglobin measurements indicated a compensatory erythrocytic response to the acid exposure. Unlike the decrease in venous blood oxygen tension observed with acute (four-day) acid exposure, oxygen tension levels from subacute acid exposed trout were normal. These data in combination with cytophotometric measurements of feulgen-DNA and azure b-RNA in immature erythroid cells from the kidney suggest that trout can acclimate to prolonged acid exposure and reach a new level of homeostasis.
