Abstract: With the rapid development of sea urchin culture and production，it is imperative to study and develop formulated feeds for this economical species.Up to now，there are ten species that has been intensively studied and cultured.The effects of feeding frequency，stocking density，environmental factors（temperature，dissolved oxygen，illumination intensity and ammonia nitrogen）on feed intake of sea urchins are reviewed.Then，nutrient requirement for protein，lipid，fatty acid，cholesterol，vitamin and mineral were described.At last，some key problems which limited the application of formulated feeds and questions which need to be solved in the further studies are discussed.This will be helpful for the development of formulated feeds for sea urchins.
