Abstract

The invention discloses a mixed culture method of oysters and microalgae, which comprises the following steps: 1) constructing a hanging culture device, which comprises a positioning pile, suspensioncolumns and an attached matrix, wherein the suspension columns comprise an upper suspension column and a lower suspension column; each suspension column is a hollow column made of transparent polypropylene plastic mesh with a hole diameter of 2-5 cm; the top of the upper suspension column is of an open structure; an air bag is arranged in the lower suspension column; a hook is arranged on the outer side surface of the lower suspension column; the attached matrix hangs on the lower suspension column by the hook, and comprises a plurality of breeding boxes connected in series; the lower end of the lower suspension column and the upper end of the upper suspension column are respectively fixed on the positioning pile through a lower cable and an upper cable; 2) culturing the microalgae; 3) culturing the oysters; 4) conducting culture management. According to the mixed culture method of the oysters and the microalgae, the oysters have the advantages of high content of taurine and unsaturated fatty acid and the like.

Description

technical field [0001] The invention relates to the technical field of mariculture. More specifically, the present invention relates to a method for mixed culture of oysters and microalgae. Background technique [0002] Oysters are rich in glycogen, taurine, 10 kinds of essential amino acids, glutathione, vitamins A, B1, B2, D, inorganic substances such as copper, zinc, manganese, barium, phosphorus and calcium, etc., which contain The content of leucine, arginine and citrulline is the most abundant, and it is one of the marine species with the highest content found by humans so far. And, the meat quality of oyster is delicious, nutritious, is deeply liked by numerous people. However, traditional oyster culture is mostly carried out with oyster strings, and the oysters in this culture method are easy to fall off due to the weak adsorption of oysters, resulting in a reduction in oyster production. Contents of the invention [0003] An object of the present invention is t...
