Abstract
Food preferences of sea urchin Paracentrotus lividus Lamarck have been studied under laboratory conditions. Four different experiments were carried out using tanks filled with fresh seawater. Six individuals were placed in each tank and they were offered pairs of algal species to select and feed upon. Gut content analysis showed that it fed selectively on these algae. The range of feeding preference from “preferred” to “non preferred” was: Ulva rigida > Dictyota dichotoma Enteromorpha linza Cymodocea nodosa Codium fragile Cladophora prolifera Padina pavonica Halopteris scoparia Cysloseira spinosa Posidonia oceanica Halimeda tuna Digenea simplex.
