The invention discloses a pollution-free healthy culture method of grouper in a pond, which comprises the following steps: (1) pond preparation: selecting sand substrates or silt substrates as pond substrates, firstly insolating and dredging, then pouring the substrates into deep sea water, applying quick lime per mu for sterilizing and improving the substrates, and discharging the quick lime after 24h; (2) working before seeding: after the pond is prepared well, pouring water, sterilizing the whole pond with chlorine dioxide, and applying special fertilizer for aquiculture and beneficial microbial agents containing bacillus after 24h; (3) seedling stocking: stocking seedlings according to the density of 700-1300 per mu; (4) bait feeding: feeding fresh sea water trash fish cream at the early stage of culture of seedlings, and feeding soft granulated feed or special commercial feed for grouper at the middle and later stages of culture of seedlings; and (5) water quality management: controlling the transparency and the pH value of pond water, and regularly applying beneficial microbes once into the pond. The culture method of grouper of the invention controls the water quality by applying beneficial microbes and organic fertilizer, reduces the use of medicines and improves the value of products.
