Shrimp is marine farmed.

The main reason for seawater aquaculture of prawns is the salinity and water quality requirements of prawns. Prawn is a subtropical and tropical marine organisms, the salinity requirements are high, generally between 20-35 ‰. At the same time, prawns are also more stringent requirements for water quality, need clear, oxygen-rich water.

When farming prawns in seawater, farms usually establish seawater aquaculture pools or ponds to maintain suitable salinity and water quality by introducing seawater. The water in the ponds needs to be circulated and filtered to maintain stable and clean water quality. The advantage of seawater aquaculture of prawns is that it can utilize the abundant marine resources and provide a suitable growing environment. Compared with seawater aquaculture, freshwater aquaculture of prawns is relatively rare. This is because prawns are marine organisms and are less adaptable to freshwater.

Differences between mariculture and freshwater aquaculture:

1, water source

Sea water aquaculture uses seawater as the source of aquaculture water, while freshwater aquaculture uses freshwater. Seawater aquaculture usually requires the introduction of seawater to maintain proper salinity and water quality, while freshwater aquaculture can utilize natural freshwater resources or provide water through freshwater treatment equipment.

2, salinity

Saltwater aquaculture aquaculture water salinity is higher, generally between 20-35 ‰, which is in line with the growth and development of marine organisms. And freshwater aquaculture culture water salinity is lower, usually between 0-2‰. Therefore, for some marine organisms with higher salinity requirements, such as marine fish and shrimp, mariculture is a more suitable choice.

3. Water quality

Sea water aquaculture needs to maintain the clarity and oxygen-rich nature of the water to meet the needs of marine organisms. Seawater contains high levels of salts and trace elements, which can provide a suitable growing environment for marine organisms. Freshwater aquaculture, on the other hand, needs to pay attention to the cleanliness of the water body and the stability of water quality to avoid the occurrence and spread of diseases.

4, aquaculture environment

Sea water aquaculture usually requires the establishment of seawater aquaculture ponds or ponds, through the introduction of seawater to maintain the appropriate salinity and water quality. Seawater aquaculture also requires attention to the influence of marine environmental factors such as tides and surges. Freshwater aquaculture, on the other hand, can be carried out in freshwater environments such as rivers, lakes and ponds, where the aquaculture environment is relatively more stable.

5, breeding species

Because of the differences in water sources and breeding environments, seawater aquaculture and freshwater aquaculture are suitable for different breeding species. Seawater aquaculture is suitable for aquaculture of marine fish, shrimp, shellfish and other marine organisms, while freshwater aquaculture is suitable for aquaculture of freshwater fish, shrimp, crabs and other freshwater organisms.
