Effect of sewage cultured Lemna minor on growth of Mollinesia latipinna was investigated using three different types of feeds viz.control feed (F1), raw lemna incorporated feed (F2) ,and decomposed lemna incorporated feed (F3) for 20 days. The feeds were prepared by using sewage cultured L.minor .The test animals fed with decomposed lemna incorporated feed showed high production (0.205) ,Gross growth efficiency (11.08 %), Net growth efficiency (11.39 %) ,Assimilation efficiency (97.31)and Metabolism (1.61). Raw L.minor incorporated fish feed showed slightly low value of Metabolism (1.58), Assimilation (1.75) and relative growth efficiency.
