What Kind of Seafood Is a Scallop? Detailed Guide to Scallop Farming Methods and Temperature Requirements
The scallop is a common aquatic shellfish with a wide distribution along the coastal areas of China. It has a smooth, tender texture, and many people enjoy eating it. It is also considered a relatively precious seafood product in China, and artificial scallop farming is now gradually being developed there. However, because it is a shellfish, many people do not know exactly how to farm it. Below, the editor will give you a brief introduction. Let's take a look!
1. Site Selection
Before farming scallops, we should carefully observe their growth habits, as scallops have different environmental requirements at different growth stages. Therefore, when choosing a site, we should pay attention to the environmental and biological factors of the farming sea area, such as water depth, salinity and temperature, to ensure the site is suitable for scallops. The farm is generally divided into different farming zones according to the different growth stages of the scallops, such as the seedling 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 Breeding
After long-term artificial farming, some artificially bred seedlings are now gradually available, such as the Pacific oyster and the European oyster. Compared with wild breeding, artificial breeding methods are now more commonly used. First, we need to do a good job in raising the parent shellfish, strengthen management, and carry out artificial fertilization of the parent shellfish to increase the fertilization success rate of the scallops. After the parent shellfish successfully spawn, larval rearing should be done well. The farming cost of artificial breeding is relatively low. The main thing is to control the living conditions of the scallops well, make use of their growth period to promote their growth, and cultivate excellent varieties.
3. Grow-Out Management
There are many ways to manage the grow-out of scallops, generally based on the seabed method. First, the scallop seedlings are scattered on the mud and sand of the seabed in the intertidal zone. Pay attention to density, which can also be understood as "sowing" the scallops. Before scattering the seedlings, the soil should be loosened to avoid the presence of predators, and then protective trenches should be dug. Carry out rearing in sections. The seabed grow-out method has very low costs and is the method most commonly used by major farmers. However, its growth rate is relatively slow and it is under relatively great threat from predators, so the specific method still depends on the actual situation.
4. Fattening Management
After passing through the grow-out period, the 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 predators, otherwise the threat to scallop growth is very great.
