The present study was undertaken to evaluate the value and inclusion of some available aquatic plants in the diet of Nile tilapia, Oreochromis niloticus, fingerlings held in net-enclosures in frtilized earthen pond at El-Mex Research Station, National Institute of Oceanography and Fisheries, Alexandria. The plants chosen were pondweed (Potamogeton pectinatus); coontail (Ceratophylim demersum) and duckweed (Lemna lemna). Comparing the results revealed that: 1) no significant difference were found in percentage dry matter, crude protein and ether extract of fish carcass composition, fed different levels of aquatic plants (25% and 50%) in the diet, but ash percent was significantly increased as the proportion of aquatic plants increased in the diet; 2) the fish tend to have more protein and less ash when fed diet containing 25% and 50% duckweed or 25% pondweed; and 3) tilapia used feed very efficiently at a level of 50% of the standard diet by duckweed and 25% by coontail or pondweed without any significantly adverse effects on appetite, feed utilization and growth performance.
