“…Other floating plants, such as Azolla sp. and some duckweed genera (Lemna, Wolfia, Wolfiella and Spirodela), have nutritional value for fish and in certain conditions can provide other beneficial ecological properties and ecosystem services (Tsuruta et al 2011;Zhao et al 2014).…”

Ecological intensification is a new concept in agriculture that addresses the double challenge of maintaining a level of production sufficient to support needs of human populations and respecting the environment in order to conserve the natural world and human quality of life. This article adapts this concept to fish farming using agroecological principles and the ecosystem services framework. The method was developed from the study of published literature and applications at four study sites chosen for their differences in production intensity: polyculture ponds in France, integrated pig and pond polyculture in Brazil, the culture of striped catfish in Indonesia and a recirculating salmon aquaculture system in France. The study of stakeholders' perceptions of ecosystem services combined with environmental assessment through Life Cycle Assessment and Emergy accounting allowed development of an assessment tool that was used as a basis for co-building evolution scenarios. From this experience, ecological intensification of aquaculture was defined as the use of ecological processes and functions to increase productivity, strengthen ecosystem services and decrease disservices. It is based on aquaecosystem and biodiversity management and the use of local and traditional knowledge. Expected consequences for farming systems consist of greater autonomy, efficiency and better integration into their surrounding territories. Ecological intensification requires territorial governance and helps improve it from a sustainable development perspective.

“…In the current study, rice planting density (1.5 × 10 5 plants/ha) on traditional rice fields was lower than on industrial rice farms (2.4 × 10 5 plants/ha), because of the RFCSs in the former. The RFCSs enables the cultivation of fish and other aquatic fauna, resulting in rest sites, foraging sites and a rich food resource for waterbirds (Stafford, Kaminski, & Reinecke, ; Tsuruta, Yamaguchi, Abe, & Iguchi, ). Waterbirds avoid fields with dense vegetation (Elphick, ; Huner, Jeske, & Norling, ), and it is not surprising that waterbirds avoid industrial rice farms, which have a high rice planting density.…”

Natural wetlands in coastal areas have been reclaimed in China and other regions of Asia. The reclaimed lands have been used for large-scale industrial farming, replacing traditional farming methods, especially in rice fields. To understand the impact of land-use conversion on biodiversity, particularly of coastal migratory waterbirds, we selected two study sites in Chongming Island, China, representing traditional rice fields versus industrial rice farms. At each site, we carried out waterbird population surveys, measured the environmental factors hypothesized to be important in determining waterbird abundance, and analyzed the effects of the different farming patterns on waterbird populations. Over two annual cycles (from August 2013 to May 2015), 39 waterbird species were observed, with a mean density of 29.3 AE 5.4/ha, on traditional rice fields, compared with 16 species with a mean density of 2.8 AE 0.4/ha on large-scale industrial rice farms. Our results demonstrated that waterbird diversity was higher on traditional rice fields than on industrial rice farms. Analyses of habitat characteristics and waterbird populations showed that traditional rice fields had more preferred habitats for waterbirds, such as more open-water cover areas, lower bare mud cover areas, lower rice plant density, no concrete-covered areas and flooding in the winter. The results suggested that the replacement of traditional rice fields with large-scale industrial rice farms has had a significantly negative impact on migratory waterbirds using the East Asian-Australasian Flyway; such a change could also have detrimental effects on waterbird conservation efforts in China and other countries along this important migration route.

“…The paddy elds can provide capacious space, shelters and natural food for cultured animals. Cultured animals are able to prey on pest, meanwhile, activities of cultured animals could loosen the soil and provide organic fertilizer for paddies thus signi cantly decrease the utilization of chemical fertilizers and pesticides [24,25]. Therefore, the coculture mode has been considered as an economical and ecological culture mode in rice-growing regions.…”

Background Chinese soft-shell turtle (Pelodiscus sinensis) is an important commercial species for its high nutritive and medicinal value, but it has been a vulnerable species due to habitat loss. In this study, homologous juvenile turtles were allocated to lake, pond and paddy field to investigate the habitat effects on turtles. Results The growth, morphology and gut microbial communities were monitored during the 4 months cultural period. It showed higher growth rate of turtles in paddy field and pond. The appearance, visceral coefficients, gut morphology and microbial communities in turtles were distinct among different habitats, which was mainly attributed to food abundance and living space. The diversity of gut microbial community was obviously higher in turtles from paddy field than pond and lake. Significant differences on dominant phyla, genera and species were found among initial samples and subsequent samples from different habitats. Firmicutes was the most abundant phylum in turtle gut sampled from greenhouse at initial and Proteobacteria was the most abundant phylum after cultivated in different habitats. The functional predictions indicated that both habitat type and sampling time had significant effects on metabolic pathways, especially amino acid and carbohydrate metabolism. Conclusion The microbial abundance was different among the habitats and varied within cultural periods. Gut microbes in turtles from paddy field presented high diversity and richness. Rice-turtle coculture was a potential ecological and economic farming mode for its high production and quality of both turtles and rice, which would play important roles in wild turtle protection, food security and paddy field environment improvement.
