Cultivation methods and characteristics of oysters

Oysters are a kind of seafood that is more popular in our country at present. At present, the more popular breeding methods include column, foot insertion, sling, floating raft, etc. So let's briefly introduce how to use these methods to breed:

1. Breeding method 1: column
Cement column is generally selected here. This method has low cost and good adhesion effect. It is bulky and not easy to be driven by seawater. First, the surface of cement column should be as rough as possible, with a size of 2m high and a diameter of 30cm thick, so that oysters will have strong adsorption. Second, cement column needs to be placed in silt zone for a period of time before moving to the seabed. This is called column can provide a good nutrition foundation for newborn oysters, attention should be paid to the timing inspection of dumping phenomenon should be timely righting, suitable for the seabed with fast flow rate.

2. Breeding method two: floating raft
This wooden bamboo is usually tied together with a buoy to float with the sea surface. The size of the raft is about 5*8m, which will affect the overall output. No matter how small the cost is, it is generally fixed on the seabed with ropes to avoid drifting with the waves. Ropes can also be used to connect with each other to prevent the seabed rope from being broken and unable to be found. The spacing between the two rafts is about 20m, which is more practical in calm shallow sea.

3. Breeding method three: bamboo insertion
One kind that is easy to understand is to insert bamboo in the seabed, provided that the bamboo has been treated in various ways. Generally, every 6 bamboos are buckled on the sea mud in a funnel shape. The length of the bamboo is controlled at about 1.5m and the diameter is more than 10cm. The parts close to the sea mud need to be surrounded by ropes for better fixation. It is generally suitable for the seabed with many soft mud and slow seawater flow.

4. Breeding method IV: Longline
This is a less laborious way. The materials are ropes and floating objects, which are generally suitable for aquaculture in open sea areas. Due to the resistance to wind and waves, the rope can also be used for aquaculture in open sea. The two ends of the rope are fixed in the dark middle of the seabed for aquaculture. The width of the middle is generally 40-50m. Look at the sea depth of the selected address. Generally, one rope is drooped every 2 meters and matched with floating objects. The length is about 3-length, daily to check whether the rope is intertwined.
