“…In general, H. mammata prefers a more stable environment, which is more important for smaller individuals, while bigger size classes tend to move to less stable environments, probably in an opportunistic fashion due to their size related resilience. This behaviour could be related to feeding conditions associated to lower predation susceptibility of bigger animals, or with a reproductive behaviour leading the broodstock, as they reach maturity size, towards more favourable areas for reproduction, since sea cucumber larvae are pelagic (Venâncio et al, 2021) and require currents for dispersion (Pedrotti and Fenaux, 1992).…”

“…Its geographical distribution covers the NE-Atlantic where it has its northern limits at the Bay of Biscay and southern limits at the meridional Macaronesian islands including the insular regions of Madeira, Azores and Canary islands, the north-African coast, occurring also in the Mediterranean sea (Tortonese, 1965;Borrero-Pérez et al, 2009). Still, the knowledge on ecological traits for this species is scarce, limited and regional, and insufficient to establish stock management policies, although relevant efforts have been put into it (Navarro et al, 2013;González-Wangüemert et al, 2014Aydin and Erkan, 2015;Mustapha and Hattour, 2017;Siegenthaler et al, 2017;Azevedo E Silva et al, 2018;Félix et al, 2018;Simões et al, 2018;Aydin, 2019aAydin, ,b, 2020Sousa et al, 2020;Venâncio et al, 2021;Azevedo e Silva et al, 2021). There are several ecological details missing, either to allow management and control of harvest activities or for future mitigation actions involving population recovery or replenishment.…”

There is an increasing demand for sea cucumbers, for human consumption, mainly from Asian markets and, as a consequence, NE-Atlantic species are now new targets for exploitation and exportation. Holothuria mammata is one of the most valuable species in Europe. However, the lack of historical economic interest in this species in most European countries has also led to a lack of studies concerning biological and ecological aspects on wild populations and this is a major issue for stock management. This study aims to determine the temporal and spatial patterns of distribution of H. mammata, considering its abundance and demographic structure in a NE-Atlantic area, SW Portugal, as a function of environmental conditions. For that, a population from a marine protected area was followed for 1 year at 1.5-month intervals. Throughout the coastal area, six sites were selected and at each sampling campaign three random transects per site and substrate (rock and sand) in which all H. mammata individuals were counted and measured. For each site and survey several environmental parameters of interest, from the water column, the sediment and substrate cover, were also measured. Generalized Linear Models were used to model the spatial and temporal distribution of the species according to environmental conditions, to determine the species’ habitat preferences. The distribution models indicate that abiotic and biotic parameters of the water column are not the main drivers shaping the distribution of H. mammata. The species has a patchy distribution, and its habitat preferences depend on environmental stability, the presence of shelter and habitat complexity, which is more important for smaller, more vulnerable, individuals, while bigger size classes tend to venture more into less stable environments in an opportunistic fashion. The knowledge of these population traits is determinant to develop stock management measures, which are now urgent to prevent the depletion of commercial sea cucumber populations in the NE-Atlantic. Sustainable fisheries policies should be developed and start by considering to delimit fishing areas and periods, considering the species spatial and temporal distribution patterns.

“…Growth and feeding methods of sea cucumbers are optimized for cultivated species but remain understudied for Holothuria arguinensis. Different settings have been tested for the growth of sea cucumbers in recent years, from different temperatures [6], different salinities [19] to different substrate sizes [20] and different diets [5], but never using the enriched substrate as a method to provide the food to any Atlantic sea cucumber species, including H. arguinensis.…”

“…However, when it comes to sea cucumber production, Europe is still behind, compared to Asia. Nevertheless, over the years there has been an increasing number of papers published in this area [2][3][4][5][6], where some European sea cucumber species have been demonstrated to be potential aquaculture candidates [2,[5][6][7][8][9][10]. Several of these temperate species are new targets for exploitation and have increasing market values [11].…”

The sea cucumber Holothuria arguinensis (Koehler and Vaney, 1906) presents an increasing commercial value in Asian markets and its exportation depends exclusively on wild stock harvesting. Production through aquaculture has been acknowledged as an alternative to supply demand and reduce pressure on natural stocks, but there are still bottlenecks to overcome, such as low growth rate and survival. This study focuses on the evaluation of the growth of juveniles of H. arguinensis through substrate enrichment—direct mixing of Sargassum vulgare with sediment—in recirculating aquaculture systems (RAS), for 4 months, with a baseline diet of Saccorhiza polyschides. Compared to the control (no enrichment), sea cucumbers fed with enriched sediment showed the highest specific growth rate (SGR), the highest growth rate (GR) and the lowest size heterogeneity. The results obtained in this study showed a favorable growth of sea cucumbers when in the presence of a substrate enriched with Sargassum vulgare, representing an important step towards the viability of large-scale sea cucumber rearing in Europe.

“…Most of the Portuguese aquaculture is developed in old salt pans in the central and southern areas of Portugal, while freshwater aquaculture is scattered throughout the northern and central regions. In any case, land-based production in aquaculture recirculating systems (RAS) or in natural systems can be an option to increase the aquaculture production and can be appropriate for some species such as flat fishes, e.g., turbot (Scophthalmus maximus), Senegalese sole (Solea senegalensis), or to produce new species such as the sea urchin Paracentrotus lividus [3,4] and the sea cucumber Holothuria mammata [5]. However, the limited areas for aquaculture production mean that offshore aquaculture may be seen as a solution for other species rearing.…”

Physico-chemical and biological parameters along the Portuguese coast were analyzed to evaluate the potential to produce aquatic species of economic interest. Water samples were collected in 2018 and 2019 in five different areas of the Portuguese coast. Currents data were collected between 2018 and 2020 and historical waves height data from 1988 to 2019. According to the results, there is a wide variety of species that can be considered for production. The northernmost area presented the lowest temperature, as well as the highest levels of chlorophyll a, and nitrate. Under such conditions, the rearing of salmon Salmo salar, mussel Mytilus edulis, scallop Pecten maximus, macroalgae Porphyra umbilicalis, and Undaria pinnatifida can be considered. Regarding the southernmost area, due to the highest temperature, this area seems appropriate for the production of meager Argyrosomus regius, sea bream Sparus aurata, sea bass Dicentrarchus labrax, and greater amberjack Seriola dumerili. This study highlights the challenges in deploying aquaculture structures on the Atlantic coast due to its oceanographic conditions. Site selection for aquaculture is a complex process and pilot studies are essential to analyze the feasibility of developing offshore aquaculture along the coast of Portugal.
