  • The papers from the first conference to bring the sea-urchin fishing industry together with the aquaculture/research community — now compiled in one volume!
  • Addresses the key areas of aquaculture: seed production, food and nutrition, husbandry issues, and marketing

Sea Urchins presents the 70+ papers presented at the inaugural International Conference on Sea-Urchin Fisheries and Aquaculture. The conference was unique in that it was the first to consider fisheries and aquaculture together–recognizing both the biology and ecology of sea urchins, as well as the needs and concerns of the fisheries as the sea urchin industry continues to grow in maintaining traditional rights and expanding their roles. Papers cover fisheries and management; ecology & population biology; biology; feeds & nutrition; seeds; and sea and land aquaculture. The volume includes a section about the future of aquaculture of sea urchins, summarized from the international roundtable discussion held at the end of the conference, which addresses issues such as environmental and business standards, biosecurity, and growth rate of the industry.
