ABSTRACT

In this study, earthworm Eisenia fetida was cultured for 60 days using the aquatic weed water hyacinth and agricultural waste. Worm meal was prepared and given to the fish Mystus montanus. The growth parameters of the fish were analysed after 60 days and compared with the fish fed with pellet diet and two different eartyhworm diets. The fish feed on earthworm meal prepared from water hyacinth showed 51.87% increase in Body weight gain, 22.22% increase in Specific growth rate, 51.43% decrease in Food conversion ratio and 55.29% increase in Protein efficiency ratio than the control group of fish. This eco friendly economical method of fish feed preparation from aquatic weed is certainly a promising one in the aquaculture field.

Key words: Water hyacinth, Agricultural waste, Vermiculture, Eisenia fetida, Fish, Growth parameters.
