NOVELTY - Method for farming maggot, involves hatching, placing maggot larva in a greenhouse or indoors after intensive treatment, at time of spring and winter, removing the larva from pond or aquaculture in the greenhouse or indoors, continuously farming the larva in biomass waste at 10 degrees C during spring and autumn and 0 degrees C during winter, separating maggots after 3-9 days, and washing the maggots. The intensive treatment is performed by forming bedding using breeding materials in ponds or aquaculture pot and breeding at 20 degrees C within 24 hours after bedding.    USE - The method is useful for farming maggot (claimed).    ADVANTAGE - The method farms maggots cost-effectively, improves breeding density by maintaining high environment temperature at early growth period, improves survival rate and cold resistance of maggots and exhibits improved utilization of land, manure and other biomass waste.    DETAILED DESCRIPTION - Method for farming maggot, involves hatching, placing maggot larva in a greenhouse or indoors after intensive treatment, at time of spring and winter, removing the larva from pond or aquaculture in the greenhouse or indoors, continuously farming the larva in biomass waste at 10 degrees C during spring and autumn and 0 degrees C during winter, separating maggots after 3-9 days, and washing the maggots. The intensive treatment is performed by (a) forming bedding using breeding materials in ponds or aquaculture pot in the greenhouse or indoors to a thickness of 5-10 cm, and breeding within 24 hours after bedding by maintaining temperature of 20 degrees C, where the breeding density is 9.6x 105-9.6x 107 unit/m2, and breeding time is 1-3 days, or (b) forming bedding using breeding material in ponds or aquaculture pot in the greenhouse or indoors to a thickness of 5-50 cm, adding yeast fermentation material, fermenting the breeding material for 0-2 days, transferring maggots within 24 hours, covering outer surface of the pond or aquaculture with biomass material for insulation, and breeding at 10 degrees C during spring and autumn and 0 degrees C during winter, where the breeding density is 9.6x 105-9.6x 107 unit/m2, and breeding time is 1-3 days.
