Abstract

Sea urchins are marine biota from phylum echinoderms that have an important role both ecological and economics. The existence of sea urchins in nature has decreased due to over fishing for marketing demand both nationally and internationally. Sustainability cultivation and management of sea urchin is an important way to maintain the marine biological resources. Conservation and cultivation of sea urchins should be done ex situ through education in universities. Sea urchin cultivation in the laboratory consists of four stages: preparation of feed, spawning and fertilization, maintenance of larvae and enlargement of larvae. In the preparation of feed should be pay attention to external factors including: temperature, lighting and chemicals as phytoplankton growing media. In the spawning and fertilization temperature and gonad maturity should not be used chemicals but only using temperature stimulation. The maintenance of larvae should be paid attention to the feed patterns used adjusted to the stages of larvae growth and development, temperature and salinity. The enlargement of larvae should be paid attention in feeding and change of water. The cultivation can provide benefits in the form of conservation or re-stocking in nature and also develop the of students’ bio-entrepreneurship skills in the field of marine biology
