Integrated rice-fish farming in hilly terraces of the Apatani Plateau, Arunachal Pradesh

Rice-fish farming is a popular activity amongst the Apatani tribe of the Ziro valley, conducted in their wet rice terraces. The strains of fish cultured include mirror carp Cyprinus carpio specularis, scale carp C. carpio communis and leather carp C. carpio nudus, cultivated synchronously with local rice cultivars (Oryza sativa), viz. eamo, ampu, mipya, pyapu, pyaping and eylang. This article describes the integrated farming practices and socio-economic circumstances of the Apatani in the Yachuli, Hapoli, Hong, Hari, Hija, Bula, Dutta and Old Ziro villages.

Aquaponics: Sustainable farming method in the fight against hunger

Aquaponics is a closed-loop system in which the waste water produced from a tank of fish is used as fertiliser to feed a bed of vegetation. In turn, the plant life filters the water through its roots and the cleaned water is returned to the fish tank for reuse. Aquaponics is a form of integrated food production system in which the wastes from one production compartment are used as inputs for others.

Integrated multi-trophic aquaculture systems: a solution for sustainability

Marine aquaculture of high value species such as fish is generally reliant on external food supplies and has a negative impact on water quality, generating high organic and nutrient loadings. Integrated multi-trophic aquaculture offers a solution to reduce environmental impact of farming systems, culturing complimentary species that can recycle nutrients and reduce nutrient pollution while generating additional products for sale. This article looks at species selection and integration of trophic levels in system design.

Harvesting Eurayle ferox (makhana) from wetland (beel) fisheries of Assam

Makhana, Euryale ferox is a perennial aquatic herb with gigantic floating leaves that grows in still, shallow water. The sowing and harvesting of makhana seeds, a casual food for rural folk, is conducted by groups of migratory people belonging to the Mallah or Sahini community of Bihar. The makhana seeds are usually fallen and scattered over the bottom of the wetlands (beels) and must be collected manually by diving during September-November. The raw seeds sell for Rs. 60-70 per kg in Assam.

A review of fresh water integrated multi-trophic aquaculture: Catching up on the dream of a blue revolution in India

Integrated multi-trophic aquaculture is a flexible concept, on which many variations can be developed and should not be viewed as confined to open-water, marine systems. Freshwater integrated multi-trophic aquaculture, perhaps better known as aquaponics, applies the same principles as those used in marine integrated multi-trophic systems. In particular, using plants to reduce phosphorus (and other nutrient) levels in effluents can help farmers meet water quality guidelines and prevent eutrophication in the environment.

Culture-based fisheries (CBF) are a useful development strategy for improving the income and food security of rural communities. CBF requires minimal capital outlay, mobilising farming communities to make use of existing small dams and reservoirs for the secondary purpose of foodfish production. The objective of this project is to introduce community-based CBF to Cambodia, and to consolidate the gains of communities that have adopted CBF in Lao PDR.
