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.

The study of rice eel farming (Monopterus albus Zuiew, 1793) in the recirculation system is to find out a suitable model for rice eel growth and contribute to responding to climate change. The average length and weight  of the rice eels were 22.28 ± 0.21 cm/inds and 14.65 ± 0.48 g/inds, respectively. The experiment was conducted with two treatments: the control treatment and the recirculation treatment; each of them was repeated 3 times in 180 days. Rice eel was fed with 80% fresh trash fish and 20% pelleted pellets with 30% protein. The results showed that the environmental factors such as temperature, pH, N-NH3-, N-NO2- and alkalinity were in suitable range for rice eel growth during the experiment. The survival rate was not different between the two treatments. Weight growth rate in the recirculation system (97.70 ± 9.04 g/inds) was higher than the control (80.67 ± 0.16 g/inds) (p<0,05). Feed conversion ratio (FCR) in two treatments was not different with 2.49 ± 0.05% and 2.41 ± 0.22%. The amount of water was added in recirculation system (3.12 m3/tank) during 180 days only 1/10 compared with thecontrol (32.8 m3/tank). These results showed that the recirculation system was perfectly suited for the growth and development of rice eel.
