Group farming for sustainable aquaculture

Abstract

Sustainable farming is a critical issue in aquaculture development. The concept is well understood but the issue is that of methodology for implementing it. It is well recognized that fragmented holdings have been a major constraint in the implementation of farming practices by small-scale farmers. In India 80 per cent of the shrimp production comes from small and marginal holdings which follow different systems of production, including the traditional `pokkali’ farms of Kerala state, improved traditional farming, and scientific methods. Group farming, which was highly successful in paddy farming, was tested among small-scale shrimp farmers practicing paddy and shrimp farming in rotation in a cluster of `pokkali’ fields in Kerala. The model served as an effective extension intervention to educate farmers on sustainability while helping them to improve their farming practices. The farmers, including women, could be equipped with the technology for farming not only shrimp but also finfish, crab and aquaculture feed production by strengthening the farmer–extensionist–researcher–political–administrative linkages. The work was done during 1993–1996 at the Central Marine Fisheries Research Institute, Cochin, India. The study formed a part of the action research project on empowerment of rural communities through extension.
