Scallop Farming Methods and Key Technical Points
The scallop is a common aquatic shellfish with a wide distribution along the coastal areas of our country. Its texture is smooth and tender, and many people enjoy eating it. It is also a relatively precious seafood product in our country, and artificial farming of scallops has gradually begun in recent years. However, because it is a shellfish, many people do not know exactly how to farm it. Below, the editor will give a brief introduction for everyone. Let's take a look!
1. Site Selection
Before farming scallops, we should carefully observe their growth habits. Scallops have different environmental requirements at different growth stages. Therefore, when selecting a site, we should pay attention to the environmental and biological factors of the farming sea area, such as water depth and salinity temperature, to ensure the site's suitability for scallops. The farm is generally divided into different farming zones according to the different growth stages of scallops, such as the spat collection zone and the nursery zone. It is also necessary to ensure that the farm is convenient for production and has convenient transportation, making production and later transport easier.
2. Artificial Seedling Rearing
After long-term artificial farming, there are now gradually some artificially bred seedlings, such as the Pacific oyster and the European oyster. Compared with wild seedling rearing, artificial seedling rearing is now more commonly used. First, we need to do a good job in breeding the parent shellfish, strengthen management, and carry out artificial fertilization of the parent shellfish to improve the fertilization success rate of scallops. After the parent shellfish successfully spawns, larval rearing should be done well. The farming cost of artificial seedling rearing is relatively low. The main thing is to control the living conditions of the scallops well, make use of their growth period, promote their growth, and cultivate excellent varieties.
3. Grow-out Management
There are many methods for grow-out management of scallops, generally mainly the seabed method. First, the scallop seedlings are scattered on the mud and sand on the seabed in the intertidal zone. Pay attention to density, which can also be understood as "sowing" the scallops. Before scattering the seedlings, loosen the soil to avoid the presence of enemies, and then dig protective trenches. Carry out rearing in sections. The seabed grow-out method has very low cost and is the most commonly used method by major farmers. However, its growth rate is relatively slow, and it is under relatively great threat from enemies, so the specific method still depends on the actual situation.
4. Fattening Management
After passing through the grow-out period, scallops can actually be harvested and sold, but in order to improve the quality of the scallops and increase yield, we should still try to carry out fattening work before harvest. First, move the scallops from the grow-out area to the fattening ground to promote their growth. The fattening ground must ensure sufficient feed. Under conditions of sufficient feed, even with relatively extensive management, the scallops can reach high quality after about 2 months of growth. The scallops can also be moved near the low tide line to increase their feeding time and promote fattening.
The above is a brief introduction to scallop farming methods. Scallop farming is very simple, but we should pay attention to doing a good job in preventing and controlling enemies, otherwise the threat to the growth of scallops is very great.
