Abstract

The aims of this research was to examined the effect of fermented giant salvinia meal as feed ingrediant on growth, spesific growth rate, feed efficiency, and survival rate of tilapia. Research used completely randomized design with five treatments and three replications. The treatments were treatment with out used giant salvinia meal, and using 10%, 20%, 30%, and 40% fermented giant salvinia meal in feed formulation.
