Healthful aquaculture method of turbot

Abstract

The invention relates to a healthful aquaculture method of turbot. The method comprises the steps of: preparing a pond with clear water quality, the depth of 2.0-2.5m and the pH value of 7.0-8.5; preparing a net cage made of polyethylene meshes; putting adult turbot into the pond in the early morning of the time period from the middle of March and the middle of April since the water temperature in the time period is 15-20 DEG C; intercropping 2250-3000 / hm2 of silver carp fingerlings and 375 / hm2 of spotted silver carp fingerlings with the lengths of 10-12cm; adopting a method combining mixed feed and animal feed, wherein the crude protein content of the mixed feed is 35%, and the animal feed mainly comprises fresh or frozen chubs, carps, wild fishes and animal liver; putting more animal feed, and feeding the turbot by the animal feed and the mixed feed according to 1-4% of the weights of the turbot.

Description

technical field

[0001] The invention relates to an aquaculture method, in particular to a method for healthy turbot cultivation. Background technique

[0002] Turbot ( Scop hthalmus max imus ) is a cold-water bottom-dwelling marine fish native to Europe, belonging to the order Pleuriformes, the family Flounder, 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 development target in many countries such as Europe and Chile in South America.

[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 in Europe. Strong re...

Embodiment Construction

[0010] The preferred embodiments of the present invention will be described in detail below; it should be understood that the preferred embodiments are only for illustrating the present invention, rather than limiting the protection scope of the present invention.

[0011] A method for healthy breeding of turbot, comprising the following steps:

[0012] (1) Breeding environment: the cultivation pond is a round or square cement pond with an area of ​​12~20m2 and a depth of 0.7~1.0 m; the middle cultivation pond is a round or square cement pond with an area of ​​30~50 m2 and a depth of 0. 8~ 1. 0 m, good water circulation and sewage discharge function are required; the water quality is transparent, clear, free of harmful heavy metal ions, sulfide does not exceed 0.02mg / L, the total number of E. coli is less than 5000 / L, and the salinity is at 20 above; light: 500lx~1500lx, uniform, soft, not dazzling; water temperature: 15℃~18℃; salinity: suitable salinity is 25~30; pH maintain...
