Zooplankton in the organic based mountainous paddy fields play an important role for the holistic development of fisheries and aquaculture sector, promoting livelihoods, food and nutritional security. Five major communities of zooplankton namely Cladocera, Copepoda, Rotifera, Protozooplanktonand Ostracoda were found in the study area where 34 species under Cladocera, 7 species under Copepoda along with some nauplii, 17 species under Rotifera and 1 species under Ostracoda and among protozooplankton 5 species under Protozooplankton, were recorded. Simpson dominance index revealed that Bosmina, Chydorus, Cyclops, Diaptomus, Brachionus, Keratella, Arcella were found as the most dominant zooplankton species. Shannon diversity index showed that Cladocera (2.45)> Copepoda (1.44)>Rotifera (1.30)>Protozooplankton (1.27). Margelef richness index showed that Cladocera (5.64)> Copepoda (1.65)> Rotifera (1.10)>Protozooplankton (1.33). The physico-chemical parameters of the rice field water as well as the structure and dynamics for the growth and abundance of zooplankton in the rice field also the productivity of rice and fish yield. It can be concluded that diversified zooplankton species has found in the organic nature paddy fields which have the reflection of the healthy ecosystem of Organic paddy fields. This type of ecosystems will be helped to attain of the three goals of sustainable development viz. Goal 12 (Responsible consumption and production), Goal 13 (Climate action), Goal 14 (Life below water) by enhancement of blue revolution of the country.
