Feasibility of Urchin Aquaculture in a Cage System
This student research and design project studied the bulking process of urchins in several proposed systems as a means of meeting consumer demand for sea urchin roe, a delicacy in Japan and France. A prototype cage was created for the initial, short term bulking of the urchins. Twelve hundred pounds of urchins were bulked in the cage for a period of ten weeks. This resulted in an average percent roe content of 20.41%, an increase of 60.91%, over roe content of 13.5% taken when they were first collected. The survivorship of the urchins was greater than 95%. An economic analysis using hypothetical prices showed an investment in a bulking operation would yield 35-130%, indicating aquaculture could be performed on a large scale and be profitable.
