Effect of Dietary Calcium/Phosphorus Ratio upon Growth, Feed Efficiency and Blood Serum Ca and P Level in Red Sea Bream

Abstract

Dietary calcium and phosphorus content and the Ca/P ratio noticeably affect the growth rate and feed efficiency of red sea bream fingerlings. 2. The dietary Ca/P ratio, optimal at a 340 mg% Ca level for the growth of the fingerlings, is about 1: 2. 3. The Ca/P ratio of blood serum reflect that the best growth of fish is achieved when fed with a diet that has a Ca/P ratio of 1: 2. © 1973, The Japanese Society of Fisheries Science.
