The present paper deals with the uptake of radioactivity into the organs and tissues in the red sea bream Chrysophrys major, 24h after injection of [14C] eicosapentaenoic acid (20:5ω3). [14C] 20:5ω3 was biologically prepared by incubating a marine Chlorella with[1-14C] linolenic acid. The incorporation of radioactivity into the organs and tissues was determined by radioactive measurements with a liquid scintillation counter after combustion of each tissue or organ and also by autoradiography of the total body of the red sea bream. The results of the present study showed that radioactivity from [14C] 20:5ω3 was mainly incorporated into the gall bladder, swim bladder, liver, and pyloric caecum, suggesting that dietary 20:5ω3 may take part in some physiologically important metabolism in these organs.
