Sea cucumbers are highly marketable as a food product due to their nutritional value. Also, it has been suggested that sea cucumbers possess a wide range of bioactive compounds that can be used in the pharmaceutical industry. In this study, the reproductive biology of Holothuria forskali was performed by evaluating the gonadosomatic index (GI) and histological analyses of the gonadal tubules. The biotechnological potential was assessed through the evaluation of the antioxidant, antimicrobial and antitumor potential. Finally, the fatty acid profile was also evaluated. These three subjects were chosen to increase the interest and to focus the economic potential of this species rearing, predicting that it can be sold in Europe or export to Asia to be used for human consumption or for the pharmaceutical industry. The GI and the histological analysis of the gonadal tubules revealed that the range from February to March corresponds to the peak of gonads maturation. Furthermore, the methanolic fraction revealed the highest antimicrobial potential against Candida albicans with an IC 50 of 233.2 mg mL À1 . Also, this fraction presented the highest cytotoxic and anti-proliferative activities through the method for measuring cell proliferation method in both cell lines, with an IC 50 of 238.2 and 396.0 mg mL À1 for MCF-7 cells respectively and 260.3 and 218.7 mg mL À1 for HepG-2 cells respectively. Regarding the fatty acid profile, the total fat content was 4.83% and the highest values were obtained for palmitic acid (9.96%), stearic acid (11.23%), eicosapentaenoic acid (10.49%) and arachidonic acid (20.36%).

“…This preferential gene flow is shaping the population genetic structure of this species in the Spanish Mediterranean coast. In marine benthic invertebrates, gene flow is driven primarily by dispersal of pelagic larvae; in sea cucumbers, the larvae remain in the water column for 13-26 days (Navarro et al, 2012;Domínguez-Godino et al, 2015). Therefore, sea cucumbers could have high genetic connectivity and show low population differentiation over large geographical scales (Vergara-Chen et al, 2010;Valente et al, 2015).…”

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.

“…Las pequeñas diferencias en las abundancias de H. sanctori entre primavera/verano y otoño/invierno observadas en este estudio pueden ser debido a estrategias reproductivas, ya que el valor máximo del Índice Gonadal de esta especie se da entre mayo y agosto (Navarro et al 2012). Algunas especies tienden a concentrarse y agregarse en periodos reproductivos para poder incrementar el éxito de la fertilización de gametos durante el desove (Gutt & Piepenburg 1991, Tyler et al 1992, Mercier et al 2000a, como ocurre con Holothuria whitmaei en las costas australianas (Shiell 2005) o con Parastichopus californicus en Alaska (Zhou & Shirley 1996, Cameron & Frankenboner 1986.…”
