As the best choice for cultivating oysters, the cement column has a rough surface, with a height of about three meters and a diameter of about forty centimeters. In this case, its adsorption performance will be very strong, but when the cement column moves down, it needs to be placed in the mud for several days, which is called column culture.
It is common to fix the seabed with ropes, which can prevent them from drifting with the tide. At the same time, they must be connected in series. This can prevent the rope at the bottom of the sea from being broken and not being found, and keep a distance of about 20 meters. This method is very convenient in some quiet Qian Hai. Another method is to insert bamboo. This method is easy to understand, that is, insert a little bamboo into the seabed, but bamboo can only be used after various treatments. Usually six bamboos can form a pile. Funnel shape, and then put it on the sea mud. The length of bamboo should be controlled at about two meters and the diameter at about ten centimeters. If it is close to the soil in the sea, it should be enclosed and fixed with a rope. Usually, mud and seawater flow slowly from the bottom of the sea.
The long rope method needs ropes and floating objects, which is suitable for open sea farming and can resist wind and waves. At the same time, it can also be cultivated in the open sea. Don't fix the two ends of the rope deep in the seabed. The middle one is used for breeding and is 40 cm wide. Drop a rope every two meters, and add floating objects at the same time. The rope should be in the middle. The length is about six meters, so it is necessary to check whether the rope is entangled.
Be careful not to put it near agricultural sewage, because it will kill oysters or there may be toxic substances in the oysters. Attention should also be paid to evacuation and culture density, and at the same time, the culture water layer should be adjusted to strengthen typhoon resistance and raft resistance. It usually takes a year and a half to plant and harvest. It takes a week to finish the recovered oysters. This is because there will be a little mud in the body, so you must spit it out before eating.
