Problems solved by technology

[0003] The artificial culture of oysters was mainly carried out in the intertidal zone or near the shore in the early days with cement piles or wooden piles. Due to the limited breeding space, floating raft culture or longline culture was carried out in the near-shore shallow sea area. The breeding method makes the oysters submerged in seawater for a long time, unable to get the exercise of periodic dry dew, which weakens the adaptability of oysters to high temperature and high salt, the survival rate of culture drops, and mass mortality often occurs

Embodiment 1

[0022] A kind of oyster off-shore original ecological culture method, comprises the following steps:

[0023] Fixed bent frame setting: Pile at a certain distance. Before piling, remove large rocks, miscellaneous algae and harmful organisms on the seabed, and level the bottom. The piles are made of wood or steel pipes wrapped in PVC pipes. The specific length of the piles depends on The actual depth of the sea water is designed, and the lines of the piles are arranged vertically and horizontally. The vertical and horizontal intervals of the piles are 2 meters and 3 meters respectively, and the horizontal bars are fixed on the piles so that the piles are fixed to each other. When the height difference between the sea surface is 1.5 meters, the horizontal bar is made of wood, bamboo or steel structure, and pedestrian passages and work rooms are set up on the horizontal bar, which is convenient for walking, breeding operation and care on it. Fix the bamboo poles in parallel on th...

Abstract

The invention relates to the technical field of oyster culture, in particular to an offshore original ecological oyster culture method. The offshore original ecological oyster culture method comprisesthe following steps: selecting different water areas for culture at different stages of oysters, performing piling at certain intervals in a culture area, arranging pile connecting lines in a longitudinal and transverse straight line manner, and fixing transverse strips on piles, so that the piles are mutually fixed, wherein the height of the transverse strips is 1m or above greater than the seasurface in a big tide, wood strips or bamboo poles are fixed on the transverse strips in parallel to form a rectangular fixed bent frame, an oyster attachment base is hung on the transverse strips andthe oyster attachment bas is positioned between a high tide line and a low tide line, so that oyster strings are in a submerged state in a rising tide and are in a dry and exposed state in a fallingtide; and the oysters are in a primary state similar to an intertidal zone. According to the offshore original ecological oyster culture method, the survival rate of oyster breeding is increased, andthe oyster breeding space is expanded.

Description

【Technical field】 [0001] The invention relates to the technical field of oyster cultivation, in particular to an off-shore original ecological cultivation method of oysters. 【Background technique】 [0002] Oyster is a bivalve mollusk that lives sessilely in the intertidal zone, and is also an important marine cultured shellfish in my country. In the natural state, oysters live in the intertidal zone with a complex and changeable environment. The periodic fluctuations of the tide make the oysters alternately dry and submerged every day, and the environmental conditions such as salinity, humidity, and temperature change drastically every day. Get long-term exercise, strong adaptability to periodic submersion-dry dew changes, and high survival rate. [0003] The artificial culture of oysters was mainly carried out in the intertidal zone or near the shore in the early days with cement piles or wooden piles. Due to the limited breeding space, floating raft culture or longline cu...
