A kind of cultivation method and device of high-grade oyster

Abstract

The invention discloses a culture method and device for high-grade oysters. The culture method comprises the steps that firstly, a culture sea area meeting the national first-grade water quality is selected as a high-grade oyster culture sea area, and meanwhile high-grade monomer seed oysters are induced and bred; then the high-grade seed oysters are placed in the culture device, and the culture device is put in the culture sea area; finally the oysters reach the standard commercial specification through about one year of natural culture, and the oysters can be harvested. A body of the culture device is a double-layer cuboid culture frame, the culture frame is connected with a floating barrel through a polyethylene rope, a frame cover with hooks is arranged on one side of the culture frame, separation plates are arranged in the culture frame to evenly divide the frame into four boxes, each box of the frame is provided with a net cage in a matched mode, and a net cage cover with hooks is arranged on one side of each net cage. The culture method and device are suitable for open sea deep water sea area culture, the open sea is deep in water, fast in flow, large in wind and wave, good in water quality and rich in bait, the high-grade oysters with attractive shell shapes and good quality can be cultured through the method, and the diversified demands of the markets can be met.

Description

technical field [0001] The invention relates to a method for cultivating oysters, in particular to a method and device suitable for cultivating high-grade oysters in deep water areas in open seas, and belongs to the field of aquaculture. Background technique [0002] Oyster is one of the four major cultured shellfish in my country, and its output accounts for 1 / 3 of the total shellfish cultured output in my country, and accounts for more than 85% of the world's total oyster output, but my country's oyster output value is only 3% of the world's oyster export value, The oysters eaten raw in high-end hotels in major cities in my country are all imported from abroad, and the price of a single oyster is more than 40 yuan, while the price of oysters farmed in my country is only a few yuan per catty, and a single oyster is less than one yuan, which is quite different from the price of imported oysters. Far. Except that our country does not have the world-famous oyster brand like Fra...

However, the existing oyster farming methods have affected the production of high-quality oysters. Now there is an urgent need for a high-grade oyster farming method that is suitable for deep water areas with good water environments and is resistant to wind and waves, breaking through traditional oyster farming techniques to meet the scale of high-grade oysters. Improve the quality of oysters to reach the level of raw food for export, and at the same time improve the high-value utilization of deep water in the open sea
