Therefore, the cultivation of geoduck has been valued by the farming industry. At present, the main cultivation method of geoduck is to adopt the bottom sowing method and the pvc tube maintenance method in natural sea areas. Because the tolerance temperature of geoduck is 0-20 ℃ , so it is difficult to find a sea area that is completely suitable for breeding, resulting in a very low survival rate and very slow growth. It takes 4-5 years to reach the market specification, and investors cannot get the return they deserve. Therefore, in recent years, geoduck farming has stagnated

Embodiment 1
[0025] The geoduck indoor factory cultivation method used in this example is to set 24 cement cultivation ponds of 6m*6m in the cultivation workshop with a building area of 1000㎡, and the cultivation area is about 768㎡. The seed shell length of clam seedlings ranges from 8-10mm, and 360,000 geoduck seedlings are put in. The specific implementation process of the breeding experiment is as follows:
[0026] 1) Create a suitable water environment:
[0027] Adopt cement culture pond, use natural seawater, salinity 28-33, the depth of water in the culture pond is 60-90cm, arrange an air-dispersing stone every 1m at the bottom of the culture pond, a total of 25. Keep the amount of dissolved oxygen in the water above 5mg / L, use deep well water and plate exchangers for breeding circulation water, keep the temperature of the breeding water at 16-18°C, use the air regulating valve on the inflation pipeline to control the amount of air in the water, and Keep the pond water turning slo...

The invention relates to an indoor industrial aquaculture method for geoduck and belongs to the technical field of marine product cultivation. The method comprises the following steps: (1) creating the appropriate water environment: adopting a cement culture pond, using natural seawater, placing air stones at the bottom of the culture pond to enable dissolved oxygen in the water to be adequate, maintaining the appropriate temperature for geoduck growth throughout the year, and placing cultivating carries of the geoduck in the culture pond; (2) putting geoduck offspring in the culture pond: enabling the geoduck offspring to be evenly distributed according to the density of 500-1,000 / m2; (3) putting baits in the culture pond: feeding the geoduck offspring twice to six times each day; (4) changing the water and cleaning the culture pond: changing the water twice each day, fully draining the water of the culture pond, and flushing the cultivating carries and the bottom of the culture pond; and (5) evacuating and separating the offspring: evacuating the geoduck offspring on the cultivating carries once every two to three months to reduce the density. The method for cultivating the geoduck is low in input cost, high in geoduck survival rate and quick in growing speed. Large-scale production and large-area cultivation can be achieved, and the quality and benefit of the geoduck are improved.
Description
technical field [0001] The invention relates to an indoor factory culture method of geoduck, which belongs to the technical field of marine product culture. Background technique [0002] Geoduck (Panopea abrupta), the species name is Gaoya Poseidon clam, is a delicious and nutritious large benthic shellfish, mainly distributed in the western coast of Alaska to California in the United States, and mainly produced in Washington State at the border of the United States and Canada Inland waters of Puget Sound. my country needs to import about 2,000 tons of geoduck from the United States and Canada every year, worth 100-150 million U.S. dollars. The current domestic price is 400-500 yuan per kilogram, and there is a huge market demand. Therefore, the cultivation of geoduck has been valued by the farming industry. At present, the main cultivation method of geoduck is to adopt the bottom sowing method and the pvc tube maintenance method in natural sea areas. Because the tolerance ...
