Scale-Up of an Aquaculture Plant for Reproduction and Conservation of the Sea Urchin Paracentrotus lividus: Development of Post-Larval Feeds

Paracentrotus lividus gonads, often referred to as “roe” or “uni” for gastronomical purposes, are among the most appreciated seafood delicacies in Mediterranean area and worldwide. However, increasing demand human consumption has caused a growing pressure on its wild stocks, prompting need develop efficient aquaculture systems production. The set-up of effective feeds various life stages optimal procedures breeding post-larvae adult sea urchins still be improved. Here, first time, we aim at developing artificial P. because critical step improve our productive skills is post-larval growth. We tested natural prepared components speed up growth enhance survival rates post-larvae, while taking into account abiotic biotic factors influencing culture conditions three replicate sets tanks, characterized by different volumes. formulated compared them with effect fresh foods frame canonical practices. Our results indicated efficiency feed composed spirulina Ulva rigida. Statistical analyses demonstrated positive impact this diet behavior rates. In addition, efficacy urchin system, they facilitated manipulation control satisfactory post-larvae.
