Harvesting Effects on Paracentrotus lividus Population Structure: A Case Study from Northwestern Sardinia, Italy, before and after the Fishing Season

Reproductive Cycle of the Edible Sea Urchin Paracentrotus lividus (Echinodermata: Echinoidae) in the Aegean Sea

“…It is commercially harvested for its gonads, or "roe", which constitute a highly appreciated gastronomic delicacy of great economic profit [1]. As a result, a severe decline of P. lividus populations has been reported in many Mediterranean areas [2][3][4][5], leading to a gradual adoption of protective measures in some EU countries. In Greece, apart from some temporal restrictions on harvesting that were mostly addressed to amateurs, no official regulations had been established to promote the long-term sustainable exploitation of this resource, until very recently.…”

Can echinoculture be a feasible and effective activity? Analysis of fast reliable breeding conditions to promote gonadal growth and sexual maturation in Paracentrotus lividus

“…In the following years the annual catch declined to 250-300 t (Allain, 1972;Ledireac'h, 1987;Le Gall, 1987, 1990, reaching a complete disappearance of urchins from areas of former abundance (Southward and Southward, 1975;Régis et al, 1986). In Italy, despite the collection of this echinoid is regulated by law, P. lividus fishery is common in southern regions and it is performed throughout the year by illegal harvesters (Tortonese, 1965;Guidetti et al, 2004;Pais et al, 2012). As a consequence of this uncontrolled uptake, the population has been dramatically exploited in shallow subtidal rocky reef.…”

Toxic effects of Ostreopsis ovata on larvae and juveniles of Paracentrotus lividus

“…In addition, this species is largely harvested in many Mediterranean regions (Gianguzza et al, 2006;Pais et al, 2007) where its gonads (roe) are considered a culinary delicacy thus causing, in recent years, a large stock reduction due to overfishing (Pais et al, 2011). Because of this, an increasing interest for P. lividus aquaculture in many European regions has emerged both for re-population and direct commercialization (e.g.…”
