Reproduction and breeding of these species due to increasing demand for their high nutritional value are concerned. Sea urchin at present is growing around the world. There is not much experience on the propagation and cultivation of Urchin species in Iran. In this review, the expression for the reproduction and rearing of sea urchin (fertilization, larval and post-larval rearing, breeding, and brood rearing) and conventional farming systems also had been described.
