Furthermore, because reproduction quantity and output value were low, benefits from fish farming were not significant. A farmer household normally only has up to 0.7 ha for fish farming, which would yield only a few hundred yuan. This is not attractive, particularly in regions where there are many other economic options. Introduce Appropriate-Scale Management Economic benefits from rice fish farming should be improved. Because the rural economy is developing rapidly, employment opportunities are increasing and some farmers opt to leave their land for other undertakings.
Improved productivity allows other farmers to farm larger areas and to produce much more grain.
Appropriate-scale management is conducive to specialization and commercialization in the rural economy, brings economic benefits to farmers, can lead to ecological benefits by improving soil fertility, and can help reduce pesticide application and pollution. There are two types of management in fish farming. In one type, specialized households or individuals raise fish, while individual households plant rice. In this case, specialized fish-raisers take care of water management and fish farming, while other farmers plant and manage rice. The fish pits and ditches are dug by the rice-planters.
