How to raise oysters

Bamboo planting culture: a more common method of oyster culture can be cultured on the seafloor where there is a lot of soft mud and slow sea water flow, and bamboo of the right size can be inserted into the seafloor. Longline culture: convenient, can be raised in the open sea and open sea, the rope needs to be fixed in the depths of the sea floor. Column culture: can be cultured in the seafloor where the flow rate is relatively fast, with low cost and good adhesion effect. Floating raft farming: in calm shallow seas, wood and bamboo are tied together and floated on the sea with buoys.

I. Bamboo culture

1. At present, this is a relatively common way of farming, that is, bamboo is inserted into the sea floor for breeding, first of all, the bamboo is treated, and then every six bamboo is in a pile, buckled on the sea mud in the shape of a funnel.

2. The length of bamboo needs to be controlled at about 1.5m, and its diameter needs to be above 10cm. Where it comes into contact with sea mud, it needs to be reinforced by rope, which is generally suitable for seafloor culture where there is more ooze and slow flow of sea water.

Second, longline culture

1. This is a more convenient culture method, which is made of ropes and floating objects, which is generally suitable for culture in relatively open sea areas, and longline culture has a high degree of resistance to wind and waves, so it is also suitable for open sea culture.

2. The two ends of the rope need to be fixed in the depths of the sea floor, and the middle can be used to breed raw oysters. The suitable width is 40-50 meters in the middle. According to the sea depth of the selected address, the two sides can generally put a rope every 2 meters and match it with floating objects. The suitable length of the rope is about 3-5 meters. Usually, you need to often check whether the rope is intertwined.

III. Column culture

1. The use of cement column for breeding has the advantages of low cost, good adhesion effect, and bulky and not easy to be impulsed by sea water. The surface of the selected cement column should be rough as far as possible, with a height of about 2 meters and a diameter of 30cm. The column of this specification will make the adsorption of raw oysters strong.

2. Before the cement column is put into the sea floor, it needs to be placed on the silt ground for a period of time. This method is called maintenance column, which can provide good nutrients for newborn oysters. When raising the column, it needs to be checked regularly. If it is dumped, it should be righted in time. Cement column culture is suitable for the seafloor where the flow rate is fast.

4. Floating raft culture

1. The material of floating raft culture is tied together with wood and bamboo, and then floated on the sea with a buoy. the suitable size of the raft is about 5 × 8 meters. the specification will affect the overall quality and output of oysters, and the cost is relatively high if the specification is too small.

2. Generally, it can be fixed in the depths of the sea with a rope to avoid drifting away with the waves, and a rope can be used between the two ends in case the submarine rope is broken and cannot be found. The distance between the two rafts is about 20m. Generally, you can choose to breed in a calm shallow sea.
