摘要：

The digestive efficiency of Tilapia zillii fed Najas guadalupensis was studied in the laboratory. Digestion was dependent on the ability of the fish to triturate the plant tissues. Based on a dietary reference, cellulose, the total digestibility of Najas was 29.3%. Digestive efficiency of the fish for non‐cellulose organic matter, protein and fat was 55.7%, 75.1% and 75.9%, respectively. Of the total caloric content of the plant, 45.4% was assimilated. An estimate was made of the amount of Najas necessary to satisfy the caloric expenditure of the fish. Copyright © 1979, Wiley Blackwell. All rights reserved
