    <dct:description>&lt;p&gt;Trials were carried out at Mat&amp;iacute;s on holding live sea urchins and scallops in a RAS system developed by Technion, Israel, which not only recirculates the water, but additionally controls the pH and removes toxic ammonia. The aim of the trials was to test the feasibility of holding sea urchins and scallops alive in the RAS system for 10 days at 4&amp;deg;C, with at least 90% survival. The project was funded by EIT food, and the participants were Technion and Mat&amp;iacute;s.&amp;nbsp;&lt;/p&gt; &lt;p&gt;The survival of sea urchins held in the RAS system at 4&amp;deg;C was high during the first five days. Eight days from catch the survival was only 80%, after 12 days about 50% and after 15 days, 10%. Sea urchins, packed in the standard way of transporting live urchins (in polystyrene boxes at 4&amp;deg;C) were at similar quality as the RAS stored sea urchins, five days from catch and the roe was still edible at eight days from catch.&amp;nbsp;All the urchins in the polystyrene boxes were dead after 12 days storage and the roe inedible.&lt;/p&gt; &lt;p&gt;Scallops had a high survival when held in the RAS system or about 89% after 24-days at 4&amp;deg;C.&amp;nbsp;&amp;nbsp;&lt;/p&gt;</dct:description>
