The utility model provides a field-based round pond rice and fish comprehensive breeding system, which belongs to the technical field of breeding and comprises a field-based round pond breeding area, a rice planting area, a breeding tail water pipeline, a water inlet pipeline and a water source. Compared with the existing land-based round pond culture tail water treatment mode adopting three ponds, two dams, a microfilter and fruit land and forest land absorption treatment, the tail water treatment cost is greatly reduced, no topdressing is needed for rice planting, and the land-based round pond culture application range is wider; compared with most of existing land-based round pond culture tail water which is directly discharged without any treatment, the method has the advantage that emission reaching the standard is more beneficial to environmental protection and sustainability. More importantly, current pure rice planting is difficult in profit, low in rice planting enthusiasm and occasionally abandoned,
