Oyster Farm How Does it Work

The operation of oyster farms is a systematic and scientific process, involving multiple key links such as site selection, seedling cultivation, breeding and harvesting. Common breeding methods mainly include raft culture, longline culture, intertidal zone culture, etc. Each method has its own unique operation mode. ​

Raft culture​
Raft culture is currently a common oyster breeding method, especially suitable for sea areas with deep water and small waves. First, it is necessary to build a breeding raft frame, which is usually composed of buoys and ropes. The buoys provide buoyancy, and the ropes connect and fix the buoys to form a frame floating on the water. The next step is to release oyster seedlings, which can be purchased or collected by yourself. Fix the oyster seedlings on shells, ropes or other attachment bases, and then hang them under the raft frame. During the breeding process, oysters will obtain food with the flow of seawater. They grow by filtering organic matter such as plankton and algae in the seawater. Breeders need to regularly check the breeding equipment, check the growth of oysters, and promptly clean up debris and other organisms attached to the breeding base to prevent them from competing with oysters for food and living space. Generally, after 1-2 years of cultivation, when oysters reach commercial specifications, they can be harvested. When harvesting, the ropes or attachments that hang the oysters are removed from the rafts, sorted and packaged, and shipped to the market for sale. ​

Longline aquaculture​
Longline aquaculture is suitable for open sea areas and has a large aquaculture scale and flexibility. It uses ropes as the main aquaculture facilities. First, anchors or piles are fixed on the seabed, and then one end of the rope is fixed to the anchor or pile, and the other end extends into the sea. Buoys are hung on the ropes at regular intervals to make the ropes float at a certain depth below the water surface. Oyster seedlings are also attached to carriers such as shells and net bags, and these carriers are then attached to ropes for cultivation. Under this aquaculture method, oysters can grow in a wider space, and the depth and position of the ropes can be adjusted according to the seawater environment and the growth needs of oysters. During the aquaculture period, it is necessary to pay close attention to environmental factors such as seawater temperature, salinity, and pH, as these factors have an important impact on the growth and health of oysters. At the same time, regularly check the firmness of the ropes and attachments to prevent oysters from escaping or damage to the aquaculture facilities. The harvesting process of longline aquaculture is similar to that of raft aquaculture, and the carrier of attached oysters is also removed for subsequent treatment. ​

Intertidal aquaculture​
Intertidal aquaculture is the use of the tidal flats in the intertidal zone to cultivate oysters. This method is relatively low-cost, but has high requirements for environmental conditions. It is necessary to select tidal flats with smooth tides, good water quality, and suitable bottom quality. To cultivate oysters in the intertidal zone, the first thing to do is to tidy up the tidal flats and remove debris and harmful organisms on the tidal flats. Then, according to different aquaculture methods, the aquaculture site is set up by using methods such as bamboo insertion, stone throwing, and bridge type. For example, in bamboo insertion aquaculture, bamboo poles are inserted into the tidal flats, and oyster seedlings grow on the bamboo poles; stone throwing aquaculture is to throw stones into the tidal flats to provide a place for oysters to attach. Oysters cultured in the intertidal zone obtain food as the seawater floods during high tide, and are exposed to the air during low tide. Farmers need to manage according to the laws of tides, check the growth of oysters at low tide, and remove predators, such as crabs and starfish, which will prey on oysters. After a period of cultivation, when the oysters mature, they are harvested manually at low tide. ​
No matter which cultivation method is used, oyster farms need to pay attention to water quality management and disease prevention and control. Regularly test the water quality to ensure that the various indicators of seawater meet the requirements for oyster growth. When there is a problem with the water quality, take corresponding improvement measures in time, such as changing water and adding water quality improvers. At the same time, do a good job in disease prevention, keep the breeding environment clean and hygienic, and avoid the spread and outbreak of diseases. Only through scientific and reasonable operation and management can oyster farms achieve high and stable production and provide the market with high-quality oyster products.
