Fish culture in mountainous paddy fields with varieties of indigenous paddies in Ziro valley north eastern part of India
Apatanis practice the sedentary agriculture and developed a systematic and eco-friendly system of integrated rice with fish culture and millet on the bund. The agricultural operations are carried out through human labour. Broadly, there are three indigenous caltivars of rice namely Emo, Mipya and Pyaping. Each caltivar of rice has own different strains. Common carp is the most cultured fish species with medium and late varieties of cultivars in the paddy field of Ziro valley whereas the grass carp is usually grown in fish ponds only. Fish nurseries are being supplied from both the private and government fish nursery ponds to the local farmers in order to culture in their paddy fields. Some farmers culture two batches of fish in a crop season where there is regular water supply and free from soil erosion and flood zone. However, most of the farmers prefer single batch of fish during entire crop season in Ziro valley. This paper attempt to analysed the fish culture with different varieties of paddy which are most suited to the fish growth in line with the maturity of crops. The researcher has cultured fish in own paddy fields and also visited all the seven villages to collected the primary data to draw conclusion on the set objectives.
