Abstract: Rice and fish have been an essential part of the life of Indonesian people which produce from rice field. The research was conducted during two years (Dec.2008 to Sept.2010) using a purposive random sampling using three plots in lowland and terrace from Manik Rambung Rice Field (MRRF). Two types of rice crops (Ciherang and IR 64) are cultivated showed 6 orders, 21 families, 34 taxa and 25 species. Oligochaeta, Ephemeroptera, Hemiptera and Diptera were identified respective families, while families of Odonata and Coleoptera were further identified to species. There are three categories of Dominance Index (DI) in rice field, these are: D=Dominant ( 5% individual); A=Accessory (2.5%  D  5% individual) and O=Occasional (2.5% individual) with four families (Baetidae, Chironomidae, Tubificidae and Ceratopogonidae) as ranked high on the DI list. The Kruskal-Wallis test showed significant differences between abundance of aquatic organisms during the time of sampling (χ2=1274.840, P=0.000), rice growing seasons (χ2=16.393, P=0.001) and rice cultivation phases (χ2=8.618, df=4, P=0.004). The study about fish farming produce plant and animal proteins and sustainable for food security in Northern Sumatra.
