The presence of heavy metals in seawater is a major challenge for hatchery culture of sea urchin larvae due to their sensitivity to metal pollution. The impact of heavy metals in seawater for sensitive marine larviculture could be minimized via chelation of metals using chemical compounds such as ethylenediaminetetraacetic acid (EDTA).

乙二胺四乙酸对长刺海胆Diadema antillarum幼虫生长和存活的影响

由于海胆幼体对金属污染敏感，海水中重金属的存在是海胆幼体孵化场养殖的主要挑战。通过使用乙二胺四乙酸 (EDTA) 等化合物螯合金属，可以最大限度地减少海水中重金属对敏感海洋幼体养殖的影响。
