Abstract

There are obstacles in the aquaculture business that is still often facedbyfarmers, one of the challengesisthe high price of commercial feed. Feed as an energy source for growth is a reasonably high-cost component in production that reaches 40-89 %. In the control of food for efficiency, it could be done by the fasting method. This research was aimedtoanalyze the effect of periodic fastedofgiant prawn (Macrobrachium rosenbergii de Man, 1879) against growth and feed efficiency. This research was conducted at IBAP Installation, Probolinggo District - East Java Province. The experimental method used completely randomized design with five treatments and three replications, such as; P0: feeding without fasting (as control), P1: a-day fasted, a-day feeding, P2: a-day fasted, two-days feeding, P3: a-day fasted, three-day feeding, P4: a-day fasted, four-days feeding, P5: a-day fasted, five-day feeding. The results showed that periodic fasted of M. rosenbergii no significant effect on the daily growth rate, absolute weight growth, and feed efficiency. However, by looking at the rate of growth, thisfasting methodcouldbe used as an alternative to saving feed. The P5 showed the most effective in increasing daily growth rate, absolute weight growth, and effectiveness of giant prawn feeding. The strategy of periodic fasted to increase the production of giant prawns should consider the other supporting factors such as ideal water quality (pH, temperature, and DO), proper stocking density, and feeding periods on schedule.
