Reinforcement type wind wave resistant oyster cultivation method

Abstract

The invention discloses a reinforcement type wind wave resistant oyster cultivation method, which comprises the following steps: in a buoyant raft type hanging mode, firstly, clamping a scallop shell attached with an oyster juvenile mollusk in the screwing gap of a clamping rope; fixing the scallop shell onto the clamping rope by single strand of high-strength fish wire; according to the amount of the oyster larvae, fixing one scallop shell substratum at a certain fixed distance; and finally, hanging the clamping rope on a buoyant raft for cultivation. The reinforcement type wind wave oyster cultivation method has the advantages that the cultivated oyster is prevented from falling in the mode that the clamping rope used for the cultivation is thickened and the single strand of fish wire is used for reinforcement under the offshore cultivation environment of big wind wave, and yield loss caused by the wind wave is reduced. The operation method is simple and easy to realize, and has an important function on lowering the management cost in the oyster cultivation process and improving the oyster yield.

Description

Technical field [0001] The invention belongs to the technical field of shellfish breeding, and specifically is a reinforced anti-storm oyster breeding method. Background technique [0002] Oysters are sessile shellfish, which rely on their left shells to remain fixed and stop moving for life, and filter planktonic algae through the closure of their right shells. Oyster is an important species of shellfish culture in our country, and its output accounts for about 70-80% of the entire marine aquaculture output. It is a good source of protein, zinc and taurine. [0003] Oyster farming does not require artificial bait and is a typical carbon sink green industry. However, due to the country's re-planning of the marine economy and the rapid development of coastal ecotourism, the area of ​​offshore culture has been greatly reduced. These factors make oysters Farming develops from nearshore farming to far shore farming. According to different culture areas, oyster culture methods are mai...

Problems solved by technology

In the case of increasing labor costs, this increases the cost of oyster cultivation, and in the cultivation process, the secondary shell of oysters is easy to cut the scallop cages used for cultivation, which also increases the cost on the other hand

[0004] Application No. 200910018386.8 "An Algae Anti-Wind Wave Sinking Rope Breeding Facility and Method", Application No. 201120065471.2 "Anti-Wind Wave Soft Frame Abalone Culture Device", Application No. 201020517268. The utility model patents such as wind and wave-resistant hanging culture device have studied the culture devices of different marine products, but there is no report on oyster wind-wave resistance culture technology.
