Abstract
An investigation was carried out to evaluate the effect of selected plants (Sesbania grandiflora, Moringa oleifera, Coleus
aromaticus, Ocimum basilicum and Solanum verbascifolium) supplemented feed on the growth parameters such as length
gain, weight gain and specific growth rate of Oreochromis mossambicus. Five experimental feeds were prepared by adding
5 grams of plant powder to the basal diet and one control feed without plant powder. The fishes were supplemented with
these feeds for 45 days and the results were obtained for every 15 days once. The data were anaylzed usinh one way analysis
of variance (ANOVA) and the means were separated using least significant differences. The fishes fed with Moringa oliefera
supplemented feed showed maximum increase in weight (0.96%, 1.33%, 1.78%) and specific growth rate. The maximum
increase in length was observed in the fishes that were fed Ocimum basilicum supplemented feed (1.2%, 1.6%, 2.0%). This
study indicated that inclusion of plant ingredients in fish feed resulted in superior growth performance and the formulation of
plant based diet for fish will provide new opportunities.
