Culture of fish in rice fields

Abstract

Rice is presently grown in 113 countries. Rice farming also offers a suitable environment for the culture of fish and other aquatic organism. This publication synthesizes the available information on the role that aquaculture can play in rice-based farming systems towards food security and poverty alleviation. The review describes the history behind integrating aquaculture with different rice ecosystems, the various production systems in operation such as concurrent, rotational and alternate, the modifications needed to the fields in order to integrate fish with rice farming, and the agronomic and aquaculture management that is necessary. The benefits of integration to communities - economic and environmental - are also described with reviews of the experiences from values countries. The real impacts of rice-fish farming and its future potential in terms of improved income and nutrition are significant but generally underestimated and undervalued. Notable changes have taken place in pest management in rice farming, and in fish seed production and availability making this a particularly relevant moment for emphasizing the importance of rice-fish farming. There is considderable potential for rice-fish farming to expand further in many countries and to contribute substantially towards global food and nutritional security.Freshwater fish, Fish culture
