The effect of different stock densities on the performance of giant prawns (Macrobracium rosenbergii) and rice production in the minapadi system

Abstract

Minapadi is a prawn rearing system in rice fields that is carried out with rice plants. This study aims to increase the income of farmers with high productivity of rice yields and increase the production of giant prawns. The method used is a Completely Randomized Design (CRD) experiment with 3 treatments and 3 replications. The treatments were : P1 = stocking density of 100 ind/plot, P2 = stocking density of 200 ind/plot, P3 = stocking density of 300 ind/plot. This research was conducted for 90 days. Parameters observed were rice productivity and growth. The results showed that the best treatment was P2 = stocking density of 200 ind/plot. By producing an average rice productivity of 5.5 kg/50 m2 and the average relative growth rate of 4.72%. From the results of this study, the application of the Minapadi system with giant prawns had a positive impact on the observed parameters (P<0.05) and thus will provide benefits for farmers.
