“…Catalonia is an exploited area for this species with an annual mean value of approximately 3 648 Kg landing, and 237 fishing days per year (Ramón et al, 2010). Sea cucumber species are especially vulnerable to overfishing because of their low and infrequent recruitment, late age at maturity, high longevity, density-dependent reproductive success and slow growth rate (Uthicke et al, 2004;González-Wangüemert et al, 2014a).…”

“…Sea cucumbers play a very important role in marine ecosystems and are considered target fishery species with high economic value (González-Wangüemert et al, 2014a;Purcell, 2014). Holothurians, as primarily deposit feeders, ingest large amounts of sediment (Uthicke & Karez, 1999) and provide important ecosystem services that enhance nutrient cycling and local productivity (Ramón et al, 2010).…”

“…The parts of the animal that are collected and consumed are the internal muscle bands ("espardenya" or "llongo"), which are considered a delicacy in luxury restaurants. This species is captured as by-catch in trawl fisheries (González-Wangüemert et al, 2014a;b) and sold in Catalonia when a minimum number of 20 individuals are caught. This corresponds to a weight of approximately 0.5 kg of internal muscle bands, whereas the mean catch per unit effort is approximately 1.78 kg per boat and day (Ramón et al, 2010).…”

Parastichopus regalis (Cuvier, 1817) is the most expensive seafood product on the Catalonian market (NE Spain), with prices at approximately 130 €/Kg (fresh weight). Despite its ecological and economic importance, biological and genetic information on this sea cucumber species is scarce. Here, we provide both the first insight on the genetic structure of P. regalis using sequences of cytochrome oxidase I (COI) and 16S genes and a morphological description of its population. Individual sea cucumbers were collected in six locations along the Spanish Mediterranean coast, including an area under fishery pressure (Catalonia). We found high haplotype diversity and low nucleotide diversity for both genes, with higher levels of genetic diversity observed in the COI gene. The population pairwise fixation index (F ST ), AMOVA and correspondence analysis (CA) based on the COI gene revealed significant genetic differentiation among some locations. However, further analysis using nuclear markers (e.g., microsatellites) is necessary to corroborate these results. Moreover, the genetic and morphological data may indicate fishery effects on the Catalonian population with a decrease in the size and weight averages and lower genetic diversity compared with locations that lack fishery pressure. For the appropriate management of this species, we suggest the following: 1) accurately assessing the stock status along the Spanish coasts; 2) studying the reproductive cycle of this target species and the establishment of a closed fishery season according to the reproductive cycle; and 3) establishing protected areas (i.e., not take zones) to conserve healthy populations and favour recruitment in the nearby areas.

“…In Turkey, which is the leading Mediterranean country in sea cucumber trade, harvesting from the wild started in 1996 in the central part of the Eastern Aegean coast and it was mainly focused on H. tubulosa and H. polii. They are exported to the Asian (mainly Chinese) markets frozen, dried and salted reaching 555 tons in 2011 (Gonzáles-Wangüemert et al, 2014), where they are considered a gastronomic delicacy (Sicuro et al, 2012). Given the high export-market demand for sea cucumbers mainly for consumption (the body wall that is edible, accounts for about 56% of the total weight), cosmetics, pharmaceutical and aquarium use, the opportunities for culture of these species should be thoroughly evaluated.…”

The Collective Article ‘New Mediterranean Biodiversity Records’ of the Mediterranean Marine Science journal offers the means to publish biodiversity records in the Mediterranean Sea. The current article is divided in two parts, for records of alien and native species respectively. The new records of alien species include: the red alga Asparagopsis taxiformis (Crete and Lakonicos Gulf) (Greece); the red alga Grateloupia turuturu (along the Israeli Mediterranean shore); the mantis shrimp Clorida albolitura (Gulf of Antalya, Turkey); the mud crab Dyspanopeus sayi (Mar Piccolo of Taranto, Ionian Sea); the blue crab Callinectes sapidus (Chios Island, Greece); the isopod Paracerceis sculpta (northern Aegean Sea, Greece); the sea urchin Diadema setosum (Gökova Bay, Turkey); the molluscs Smaragdia souverbiana, Murex forskoehlii, Fusinus verrucosus, Circenita callipyga, and Aplysia dactylomela (Syria); the cephalaspidean mollusc Haminoea cyanomarginata (Baia di Puolo, Massa Lubrense, Campania, southern Italy); the topmouth gudgeon Pseudorasbora parva (Civitavecchia, Tyrrhenian Sea); the fangtooth moray Enchelycore anatine (Plemmirio marine reserve, Sicily); the silver-cheeked toadfish Lagocephalus sceleratus (Saros Bay, Turkey; and Ibiza channel, Spain); the Indo-Pacific ascidian Herdmania momusin Kastelorizo Island (Greece); and the foraminiferal Clavulina multicam erata (Saronikos Gulf, Greece). The record of L. sceleratus in Spain consists the deepest (350-400m depth) record of the species in the Mediterranean Sea. The new records of native species include: first record of the ctenophore Cestum veneris in Turkish marine waters; the presence of Holothuria tubulosa and Holothuria polii in the Bay of Igoumenitsa (Greece); the first recorded sighting of the bull ray Pteromylaeus bovinus in Maltese waters; and a new record of the fish Lobotes surinamensis from Maliakos Gulf.

“…Therefore, it is the obligation to know about edible species and their biochemical composition. Aegean Sea, Mediterranean Sea and Marmara Sea are home formany commercial sea cucumber species; Holothuria tubulosa, H. sanctori, H. polii, H. mammata, Stichopus regalis and S. japonicus species distributed along Turkish waters, are all exported as frozen, dried and salted, mainly Asian countries [1]. The overall trend in the export of sea cucumber is a continuous increase; total exportation amount carried out in 2014-2015 years was 154.203 kg, and it contributed 3.225.393 € to economy of the country [2,3].…”
