The supply fish of bileh (Rasbora maninjau) so far comes from natural catch. The catch of bileh fish in their natural habitat can cause a decrease in the population of this fish so that cultivation efforts are carried out. Feed has become one of the most important factors in cultivation activities. If the feed given is in accordance with the nutritional needs of the fish, it will support the increase in the growth of the fish being cultured. For this reason, research was carried out on the use of natural raw materials for taro plants as additional nutrients in feed. The aim of this study was to analyze the effect of adding taro leaf flour Colocasia esculenta(L.) Schott to feed by observing the growth rate of bileh fish. The experimental design in this study used a completely randomized design with four different doses of feed with three replications. The research treatment was a control treatment, dose of 5%, dose of 10%, and dose of 15% of taro leaf meal. Parameters observed were weight gain, absolute length increase and water quality. The results showed that the addition of taro leaf flour to the feed gave the same response to the parameters of weight gain, absolute length gain, and feed conversion ratio. The use of taro leaf flour has not been able to increase the growth of bileh fish (Rasbora maninjau).
