The results show that Hemicentrotus pulcherrimus is a very stric tly littoral species on rocky shore, mostly living under stone in the ebb-zone, wherethe algae and sea-grass are abundant; it takes three years to grow up the comme-rcial size(> = 30mm in diameter); the gonad index may reach the maximum value,some 20%, late in April; early in May, as the water temperature raises to 10-12℃, it enters the breeding seasoll.
