The invention belongs to the field of aquiculture, and in particular relates to an ecological cultivation method of the arca subcrenata lischke. The method comprises the steps of: treating the arca subcrenata lischke, stocking the arca subcrenata lischke, cultivating the arca subcrenata lischke in a covering way, adjusting the water quality, measuring in a sampling way, and controlling the disease. The arca subcrenata lischke is stocked according to six specifications such as the 4.2mm, 5.2mm, 6.4mm, 8.2mm, 11.6mm and 21.4mm, the stocking density is 450-550 granules / m<2>, and the growing condition of the six groups of the arca subcrenata lischke is compared with the surviving condition of the six groups of the arca subcrenata lischke. The method has the benefic effects that the stocking specification is reasonable by adopting the ecological cultivation method, the water quality is purified, the sewage discharge is reduced, the ecological environment is protected, the quality of the aquatic product is guaranteed by the three-dimensional ecological cultivation of the arca subcrenata lischke with the penaeus japonicus bate, the palaemon carinicauda and the barracuda, and the economic benefit is obviously improved.
