Problems solved by technology

However, due to the short development period of the industry and the unevenness of the employees, there are currently prominent problems such as the increase in breeding diseases, irregular drug use, and even a small number of units abusing prohibited drugs, so that unqualified commercial fish appear on the market.
Quality and safety problems caused by excessive drug residues in aquatic products have become a bottleneck restricting the production and sales of turbot

Embodiment 2

[0038] The preparation method is the same as in Example 1.

[0039] In the turbot juvenile stage of growth, pull out, divide and raise in the middle of five pools, 500 in every pool, throw in respectively the microbial turbot of the embodiment of the present invention 1 according to the input amount of 200kg per mu in four pools turbot manure and common turbot manure (control 1, produced by Beijing Century Ames Biotechnology Co., Ltd.), another tank was not put in turbot manure (comparison 2), but put in the same amount of common fish food, and the rest The feeding amount is the same, and the cultivation environment is the same. After 2-4 months of cultivation, the output and the growth status of turbot are compared, as shown in Table 1 and Table 2:

Abstract

The invention discloses a method for cultivating turbot through bacterial manure in a pond which is high in water quality. The depth of the pond is 2.0 to 2.5 m, and the pH value of water in the pond is 7.0 to 8.5. A net cage is made of polyethylene meshes. In the morning of one of the days between the middle of March to the middle of April, the temperature of the water is 15 to 20 DEG C, turbot adult fish are put into the pond, and 2,250 to 3,000 silver carp fingerlings and 375 spotted silver carps are intercropped per square hectometers and are fed by the bacterial manure, wherein the length of each silver carp fingerling is 10 to 12 cm. By adding composite bacterial manure, the rapid growth of the turbot can be promoted, the content of eicosapetaenoic acids (EPA) is increased, the disease is reduced, and the number of the turbot dying of illness is decreased; and meanwhile, the number of beneficial microorganisms in a water body is increased, and the final quality is improved.

Description

technical field [0001] The invention relates to an aquaculture method, in particular to a method for cultivating turbot with microbial fertilizer. Background technique [0002] Turbot (Scophthalmus maximus) is a cold-water bottom-dwelling marine fish native to Europe, which belongs to the order Pleuriformes, the family Flatfish, and the genus Turbot. It is mainly distributed along the Atlantic coast, the North Sea, the Black Sea and the Mediterranean Sea. Because it has the advantages of adapting to low water temperature, fast growth, delicious meat, easy to accept artificial feed, and easy to intensive farming, it has become the main breeding and development object of many countries such as Europe and South America Chile. [0003] Since turbot was introduced into our country in 1992, its culture has rapidly radiated from Shandong to the northern coastal provinces, and it has become one of the seawater cultured species in my country. Turbot is a rare economic fish species i...
