“…The differences in ingestion between diets were certainly related to the chemical and physical properties of the feed (Carboni, ; Klinger, ), although its agar‐based formulation was immediately accepted and readily consumed, as described by Fabbrocini et al (). Therefore, palatability and attraction were successfully achieved, which are key factors for artificial feeds (Cirino, Ciaravolo, Paglialonga, & Toscano, ; Cyrus, Bolton, Scholtz, & Macey, ; Fabbrocini et al, ; Lawrence, Lawrence, & Watts, ), as well as a suitable texture and form (Klinger, ; Spirlet et al, ). The inclusion of fresh triturated L. digitata in Diet B might have acted as a feeding stimulant, assuming its chemosensory characteristics were preserved (Cyrus et al, ; Klinger & Lawrence, ).…”

“…Specimens of sea Paracentrotus lividus were hand collected by scuba-diving from rocky shores of the Gulf of Naples, along the southern Tyrrhenian coasts of Italy. Animals were placed in a cooler and carried to the laboratory under moist conditions within 2 h. Sea urchins were held in suspended baskets in a semi-closed recirculating system as described in [16].…”

“…The EtOAc phases were combined, dried with Na 2 SO 4 , and evaporated under reduced pressure to give a brown-red oil extract (180.0 mg). The extract was fractioned by CC, eluted with CHCl 3 /i-PrOH and carried to the laboratory under moist conditions within 2 h.

Fatty Acids from Paracentrotus lividus Sea Urchin Shells Obtained via Rapid Solid Liquid Dynamic Extraction (RSLDE)

Sea urchins (Echinodermata, Echinoidea) are good a source of bioactive compounds belonging to different classes of natural substances. The edible Mediterranean sea urchin Paracentrotus lividus is a renowned animal model for study in different fields of biology, but it is intensively harvested for high commercial value due to the delicacy of its gonads. Most studies have focused on the composition and the nutritional value of P. lividus gonads (the edible part), but little interest has been taken in the other body parts, such as the shells and spines, which are generally considered waste material. The purpose of this study was to obtain an extract from sea urchin shells, with a green methodology of extraction, and to characterize the lipophilic components for potential applications. The shells of P. lividus were extracted via a very well performing technology based on rapid solid liquid dynamic extraction (RSLDE) implemented via an automated device (Naviglio Extractor®). The obtained extract shows the presence of fatty acids and their esters (methyl, ethyl and 1-glycerol esters). Gas chromatography-mass spectrometry (GC-MS) measurements were used to determine fatty acid abundance in the chromatographic fractions of the extract. Arachidonic acid (ARA), 5,8,11,14,17-eicosapentanoic acid (EPA), and 11-eicosenoic acids and their esters are the most abundant components. The presence of many polyunsaturated fatty acids (PUFA) in the extract, even in low percentages allows a future application in nutrition or medical use.

“…Besides their ecological importance (Willoughby, 2018; Ling et al ., 2019), sea urchins are of commercial importance (Lauzon-Guay & Scheibling, 2007; Rahman et al ., 2014). Sea urchins have been overfished around the world because of the increasing market requirements (Cirino et al ., 2017), leading to a reduction in supply. Stock enhancement, which introduces small sea urchins into the field, is an important approach to meeting the increasing market requirements of sea urchins.…”

Effects of flow velocity on fitness-related behaviours of the sea urchin Mesocentrotus nudus: new information on stock enhancement

et al. 2020

The effects of flow velocity on the fitness-related behaviours of Mesocentrotus nudus remain largely unknown, greatly hampering the efficiency of stock enhancement. To explore the appropriate velocities for stock enhancement, we investigated dislodgement and immobilization velocities up to 90 cm s−1. The experimental results showed that M. nudus (test diameter of ~30 mm) were dislodged at 73.50 ± 7.7 cm s−1 and that M. nudus movement occurred only when the flow velocity was less than 33.40 ± 2.7 cm s−1. Three flow velocities less than 33.40 ± 2.7 cm s−1 (2, 10 and 20 cm s−1) were subsequently used to study the effects of flow velocities on covering behaviour and the righting response time of M. nudus. The downstream movement velocity of M. nudus was significantly larger than that upstream at 2 cm s−1 (P = 0.016) and 10 cm s−1 (P = 0.008), but not at 20 cm s−1 (P = 0.222). The righting response time of M. nudus was significantly longer at 20 cm s−1 than that at 2 cm s−1 (P = 0.015). The present study indicates that a flow velocity less than 20 cm s−1, preferably 2–10 cm s−1, is probably appropriate for the stock enhancement of M. nudus. Notably, the current study is a laboratory investigation without considering the hydrographic complexity in the field. Further studies should be carried out to investigate the long-term effects of water flow on feeding and growth of M. nudus both in the laboratory and the field.
