The present application belongs to the technical field of shrimp, crab, shellfish and fish three-dimensional ecological aquaculture method, especially to a shrimp, crab, shellfish and fish three-dimensional ecological aquaculture method using ecological niche complementation, a salt pond in intertidal zone is selected, a culture salt pond with an area of more than 500 mu is constructed, the culture salt pond is 400-450 m wide from east to west, 850-950 m long from south to north, and 3.0-3.2 m deep, a ring ditch is excavated around the culture salt pond, a central ditch with the same direction as water inlet and outlet is excavated in the center, a shellfish bed is arranged between the ring ditch and the central ditch, and the slope ratio of water inlet to water outlet is 1.8:1.0.

The invention provides a Sichuan parabramis pekinensis offspring seed breeding method which comprises the following steps: (1) draining water and cleaning a pond: completely emptying water in the pond, and thoroughly disinfecting; (2) water feeding: well water is injected, and it is ensured that dissolved oxygen is larger than 6 mg / L; (3) detoxifying and fertilizing water before releasing the seedlings: 2 days before releasing the seedlings, mixing an antidote with water, and splashing the whole pond for detoxifying; 1 day before the fries are put, water is added into the pond to the depth of 60-80 cm, compound lactic acid bacteria biological enzyme is activated with water for 4-6 h and then splashed to the water surface of the pond, and then a water body ecological restoration agent is diluted and splashed to the water surface of the pond; (4) putting fries: putting the fries into the pond in July every year; (5) bait casting and seedling emergence, wherein no bait is cast on the first day after the seedlings are cast; 2-5 days after the fries are put, initial feed is fed according to the frequency of 3 times per day; 6-30 days after the fries are put, initial feed is fed according to the frequency of 4 times per day, and then the fries can be harvested. By adjusting the water quality, the quality of the Sichuan parabramis pekinensis offspring seeds is improved, and a safe and healthy growth environment is provided for offspring seed growth.
