“…The analysis of the published literature also revealed that lower amounts of pesticides and chemical fertilizers were used in rice–fish co‐culture than in rice monoculture. One study involving 120 farms in Vietnam showed that total application of fungicides, herbicides, and insecticides was reduced by 44% in rice–fish farming as compared with rice monoculture (Berg 2002), while in Indonesia, no herbicides were applied in rice–fish co‐culture and pesticide use was only 23% of that used in rice monoculture (Dwiyana and Mendoza 2006). A 6‐year field survey and 5‐year field experiment in southern China indicated that rice–fish co‐culture produced the same yield and yield stability as rice monoculture but with 68% less pesticide and 24% less chemical N fertilizer (Xie et al .…”

“…Moreover, rice from the rice-fish fields that has been grown with reduced levels of pesticides and inorganic fertilizer will be preferred by consumers because such rice has value added in terms of safety and security for human health [53]. Therefore, the adoption of rice-fish culture allows more stable production methods and economically benefits the farmers [3,11,21,54,55]. Consequently, a sustainable farming system can be realized by utilizing the multifunctionalities of rice-fish culture, which offers good results to farmer, consumer, and ecosystem.…”

Effect of fish in rice-fish culture on the rice yield

Rice-fish culture, which means the simultaneous culture of rice and fish, is one of the best options to increase food production from limited land and is practiced in many countries in the world. Although many researchers and farmers believe that the rice yield is increased by fish farming in paddy fields, this hypothesis has never been fully tested. Here, we report ecological processes leading to higher rice yields in the rice-fish culture using crucian carp (Carassius complex), which have adapted to the paddy field ecosystem in Japan. We compare the rice-fish and rice-only plots in the experimental paddy field for biota, water quality, and rice yield. Coverage of duckweed and densities of zooplankton and benthic invertebrates in the rice-fish plots were lower than those in the rice-only plots, indicating that fish utilized them as food. NO 3 -N concentration in the rice-fish plots was higher than that in the rice-only plots, indicating that the increase in NO 3 -N concentration results from excretion of unutilized food nutrients by the fish. Consequently, rice yield in the ricefish plots was 20% higher than that in the rice-only plots. The fertilizing effect of the fish excrement probably increased rice yield.

“…These farming patterns help the farmers to increase the revenue by limited fields. It is reported that net revenue increased from the rice-fish system over the rice monoculture ranged 5%-11% in West Africa (Ofori et al, 2005), 47%-66% in Indonesia (Dwiyana and Mendoza, 2006).…”

“…Food production is increasingly being adversely affected by agriculture and aquaculture, and also domestic, industry discharges. Pesticide residues have become nonpoint source pollution in waterways which are threatening the drinking water resources and aquatic ecosystems (Dwiyana and Mendoza, 2006;Krone-Davis et al, 2013;Matamoros et al, 2008;Moore et al, 2009;Vymazal and Březinová, 2015). Ammonia and nitrite arising from degradation of protein can be of primary toxic to aquatic organisms (Bunting, 2013;Kadlec and Zmarthie, 2010;Mook et al, 2012;Tyson, 2007).…”

The widespread use of compound pelleted feeds and chemical fertilizers in modern food production contribute to a vast amount of residual nutrients into the production system and adjacent ecosystem are major factors causing eutrophication. Furthermore, the extensive development and application of chemical compounds (such as chemical pesticides, disinfectants and hormones used in enhancing productivity) in food production process are hazardous to the ecosystems, as well as human health. These unsustainable food production patterns cannot sustain human living in the long run. Wetlands are perceived as self-decontamination ecosystems with high productivities. This review gives an overview about wetlands which are being integrated with food production processes, focusing on aquaculture.
