Summary
This 2024 field study examined rice-fish co-culture systems in Asian paddy ecosystems, investigating the ecological mechanisms by which aquaculture integration drives productivity gains through multiple pathways including nutrient cycling enhancement, natural pest regulation, and biodiversity support. The work provides empirical evidence that shared rice-fish systems can deliver sustainable intensification benefits by harnessing ecosystem services, contributing to understanding of integrated farming pathways in rice-growing regions.
UK applicability
Direct applicability to UK agriculture is limited, as rice-fish co-culture is not a commercial practice in UK temperate or cool climates. However, the study's demonstration of ecosystem-service-mediated yield gains in integrated systems may inform principles applicable to UK mixed and organic farming, particularly regarding natural pest suppression and nutrient cycling optimisation.
Key measures
Rice yield, fish yield, nutrient cycling rates, arthropod diversity and abundance, soil nutrient status, natural enemy and pest populations
Outcomes reported
The study measured yields, nutrient cycling dynamics, natural pest regulation, and biodiversity indicators in rice-fish co-culture paddies compared to monoculture rice systems. Field observations assessed how fish integration modified soil processes, arthropod communities, and overall productivity across Asian paddy ecosystems.
