【Salt Concentration of Seawater】
The salt concentration of artificial seawater used in aqua farming on dry-land for raising juvenile fish, is between 30 to 35‰. Brackish water is required for prawns and certain species of fish. The salt concentration of brackish water is generally between 0.5 to 30‰.
Researchers have measured, monitored, and recorded the salt concentration of seawater in every ocean region around the world. Interesting trends have been discovered based on this research. It seems that the beautiful coral reefs that stretch out across the sea cannot be formed if the salt concentration is not between 33 to 35‰.
From the perspective of oceanic ecology preservation, there are regions where measuring the salt concentration of ballast water in vessels (like tankers) is crucial. In the waterways around New York State, water must be more than 30‰ in order to be released back into the water system.
