Gill-perfusing experiment was carried out, using Japanese eel, Anguilla japonica, to investigate the behaviour of strontium and calcium at the gill excretion in fishes. As the internal perfusion solution, various media were used, such as KEYS physiological saline solution, blood serum of horse or that of eel, and the following results were obtained. 1) In case of using the physiological saline solution, the discrimination was observed between strontium and calcium, and calcium is more easily excreted than strontium at the gill excretion of these minerals. The discrimination rate (DRgill excretive) was 0.74 in this case. 2) In case of using the blood sera of horse and eel, this rate of discrimination was 1.00 and 0.90, respectively. In the former case, in other words, no discrimination was observed between the behaviour of strontium and calcium. In the latter case, which corresponded to the natural condition of eel, calcium was excreted a little more easily than strontium. 3) Discussion was made on these various discrimination rates obtained in the perfusion experiments of gill excretion. Strontium-calcium discrimination in gill excretion does not seem to contribute much to overall discrimination between water and fish body. The authors wish to express their cordial thanks to Dr. T. FUKAZAWA, Tokyo Metropolitan Meat Inspector Office, and Mr. T. SANO, Tokyo University of Fisheries, and members of Sanwa Fresh Water Fish Co. Ltd., for the facilities they gave to authors during the collection of blood sera of horse and eel.
