The invention provides a method for producing de-fishy low-salt half-dry freshwater fish. The method comprises the steps of pretreatment, fishiness removal and cleaning, draining, fishiness removal and preserving, bittern washing, air drying at low temperature, shaping, sealing under vacuum, product examination and warehousing. The method employs a low-salt low-temperature fishiness-removal preserving process and a low-temperature half-dry process, when fishiness-removal and low-salt purposes are reached, low temperature condition is employed, fish oxidation degree is low, fish meat quality and nutrition of the freshwater fish can be better preserved, a step-by-step style and gradual heating style air drying method with tempering at midway is employed, air drying speed and efficiency are accelerated, during a constant-temperature one-time air drying process, after fish skin is caked, problem of difficult evaporation of moisture in the fish meat can be avoided. According to the method, moisture in the fish skin can be evaporated at low temperature, the moisture in the fish meat is evaporated with steps of tempering and moisture regain treatment as well as heating, evaporation efficiency is accelerated, and air drying cannot be influenced by caking of the fish skin.
