Fish and seafood are important sources of dha. Fish such as grouper, catfish, Spanish mackerel, eel, hairtail, dike fish, yellow croaker, sardine, perch, tuna and flounder, as well as shrimp, sea crab, shellfish and squid are all rich in dha. For example,100g hairtail and large yellow croaker have dha contents of 80mg and 90mg respectively. It is worth noting that the dha content in other foods is very low except fish and shrimp. At present, there is no database of dha content in various foods in China.
