1.    Protein
The type of protein in fish is a complete essential amino acid that is easily digested by the body.


Generally, the type and amount of amino acid content in marine fish is higher and more complete than freshwater fish. This is due to the availability of natural food in the fish habitat. Natural food in marine fish is in the form of zooplankton and phytoplankton which are rich in amino acids.


2.    Fatty Acids 
Fatty acids in marine fish and freshwater fish consist of Saturated Fatty Acids (SFA), Monounsaturated Fatty Acids (MUFA) and Polyunsaturated Fatty Acids (PUFA). PUFA fatty acids are dominated by the omega-3 group which includes EPA and DHA. 


These omega-3 fatty acids are more abundant in marine fish than freshwater fish.

4.    Minerals
The mineral content in seawater and freshwater fish is almost the same, only the total amount of minerals differs.


The mineral content of fish includes mineral salts, such as Na, Ca, Mg, Cl, F, K, Selenium, and Iodine. These mineral salts are beneficial for inhibiting the growth of cancer cells. 


Other microminerals such as calcium, zinc, and iron are useful as blood enhancers and aid development in children.
