What is the difference between saltwater and fresh water fish?
Since saltwater fish have a briny flavor, you might think they contain much more sodium, but they do not. Their bodies do not absorb salt from seawater. The main difference in nutrients is that freshwater fish tend to have higher amounts of calcium, monounsaturated fatty acids and polyunsaturated fatty acids.
