The invention discloses a no-tillage direct seeding method for fish breeding in a rice field, and specifically relates to the technical field of agriculture. The method comprises the following specific steps of S1, digging fish ditches and fish pits; S2, arranging a fish blocking net; S3, breeding fishes in the rice field; S4, harvesting rice; S5, conducting fishing to put the fishes into the market; S6, conducting disinfection; S7, stocking fingerlings; S8, spreading rice seeds; S9, putting breeding fingerlings. According to the method, by breeding the fishes in the rice field, fish productscan be obtained, the fishes can also be utilized for eating pests and weeds in the rice field, the decomposition of fertilizer is promoted, and the growth of the rice is facilitated; the rice seeds are directly seeded in a no-tillage way, the ploughing labor is not needed, the time and labor are saved, although the yield of the rice field is reduced, the fluctuation of the yield reduction is small, the reduced output valu
