Abstract

The growth of Sarotherodon galilaeus fingerlings fed with test diet of 33% crude protein and containing 10% duckweed was compared with standard KLRI/40/6 feed of 40% crude protein. From an initial mean weight of 1.18gm and 1.17gm, the fingerlings in the test diet and control respectively grew to a final mean weight of 2.17gm and 1.98gm after seven weeks. With mean growth rate of 2.02% and 1.65% of their body weight per day respectively for the test diet and the control, it was obvious that the test diet was better and had a higher food conversion than the control. The duckweed must have therefore, supplied some essential amino acids to the test diet thereby making it a higher quality feed
