That the rate of uptake of S33 sulfate from the water in which the fish swim is markedly affected by the body sulfate pool of the animal is shown in Figure 5. Male Lcbistcs were equilibrated for 7 days in artificial pond water containing 15 ppm sulfate. After this period of sulfate depletion, the fish were divided into three groups and transferred to bowls containing artificial pond water prepared to contain 15 ppm, 75 ppm and 200 ppm non-radioactive sulfate in addition to S35 sulfate. Other experiments were performed in which the fish were equilibrated in artificial pond water containing 75 ppm and 200 ppm non-radioactive sulfate before the animals were subjected to the experimental conditions. The uptake of S35 sulfate by Lcbistcs after equilibration at 15 ppm appears to be non-linear when the isotope is taken up from water containing 15 ppm non- radioactive sulfate ion. The data are adequately expressed by an exponential 6 2 O 9. i 1° 2 , '£ ° m 10 LjJ * i 0 A UPTAKE FROM 15 ppm SO* I97«l05cpm/ml) 200ppm SO 4 - 75 ppm S04.
