Pokkali cultivation is the traditional method in our paddy fields for centuries long. Its a cyclic method of paddy cultivation. After the harvest, the farmers switch Pokkali fields into shrimp farms using traditional methods. So Shrimps can eat the remains of paddy leaves and after the shrimp harvest is over again rice has been started cultivation. Then the excreta of the shrimps will be nutritios fertiliser.
Fish culture in rice fields is said to be practised between latitudes 20°N and 20°S and between 1,000 and 1,500 metres altitude (Schuster, 1955; Coche, 1967). Such regions are found in Preanger highlands of Java, the Batak areas in Sumatra, the inland areas in Madagascar and the Thailand region (Coche, 1957), but it is well recognized that several paddy growing areas exist at lower attitudes - the brackishwater paddy growing areas of Bengal (“Basabada”) and Kerala (“Pokkali”) in India are coastal based.
There are about 4,000 hectares of paddy fields under pokkali cultivation in Ernakulam district, while in Alappuzha the extent of pokkali cultivation is in about 3,000 hectares. These are the facts. But genaraly, Pokkali cultivation in kerala is about to reach its end.
