Abstract

1. 1. Measurements of branchial sodium efflux rates, radiosodium spaces, and plasma ionic levels were made in southern flounder through use of a catheterization technique which permitted serial blood sampling. 2. 2. Disturbances in hematocrit and plasma sodium concentration were associated with the catheterization procedure. 3. 3. Sodium efflux rate was reduced 23 per cent in fish rendered anaemic through bleeding. 4. 4. Radiosodium spaces and plasma sodium and potassium levels were not significantly changed by anaemia. However, plasma sodium and potassium levels were positively correlated regardless of hematocrit. 5. 5. The results are discussed in terms of present theories of electrolyte balance and blood shunting mechanisms in the gills of teleosts.
