Aquaculture in the Alboran Sea began 40 years ago, but in spite of several projects to culture fish and shellfish have been developed, only a few companies are now running. The main cultured species have been sea bass, sea bream, and mussels, but attempts to culture Atlantic bluefin tuna, amberjack, sole, oyster, clams, scallop, shrimp, octopus, se...

Sea cucumbers have an important economic value and high demand. Despite that, there is a lack of knowledge about their biology, ecology and habitat distribution patterns, which is very important for sea cucumber stock management, establishment and sizing of no-take zones, restocking actions and selection of grow-out areas. This work aimed to determ...
Article
Holothuria arguinensis aquaculture started to be developed in 2014, being the first sea cucumber species from Europe. However, some aspects of its aquaculture biotechnology need to be assessed. This work aimed to evaluate seagrass debris of Zostera noltii and Cymodocea nodosa as food source for broodstock maintenance in tanks, during the breeding p...

The term profitability can be understood as the ratio in percentage between fresh weight of animals and the dry weight of the obtained bêche-de-mer depending on the body wall thickness of sea cucumbers and water content. Specimens decrease their weight and length considerably, when they are processed. However, scarce information about profitability...

Sea cucumber fisheries have developed along the northeast Atlantic Ocean and Mediterranean Sea since the early 1990s, with an important incidence of illegal harvesting across these waters. Subsequently, in recent years, research has focused on aquaculture development. Holothuria arguinensis is a commercial sea cucumber species from the northeast At...

In sea cucumbers, females maintain their oocytes in meiosis prophase I, and their maturation only conclude just before spawning. A new methodology for inducing in vitro oocyte maturation in sea cucumbers is using their nerve extract, which contain a gonad stimulating substance (GSS) that lead to oocyte final maturation, if the extract is obtained i...

For marine meta-populations with source-sink dynamics knowledge about genetic connectivity is important to conserve biodiversity and design marine protected areas (MPAs). We evaluate connectivity of a Mediterranean sessile species, Pinna nobilis. To address a large geographical scale, partial sequences of cytochrome oxidase I (COI, 590 bp) were use...
Article
Sea cucumber commercial fisheries in the North-eastern Atlantic and Mediterranean Sea started in Turkey in the 1990s. Due to ineffective management practices, the sea cucumber resource was overexploited. Holothuria mammata is one of the sea cucumber species exploited from this geographical area, showing high potential for its aquaculture. This rese...
Article
In the last years, sea cucumbers consumption is increasing in the Asian region, as consequence more than 70% of the sea cucumber fisheries around the world are fully/over exploited or depleted. Therefore, Asiatic markets are looking for new target species mainly from Mediterranean Sea and NE Atlantic Ocean. In this paper, we establish the state of...

Understanding how species grow is critical for choosing appropriate fisheries management strategies. Sea cucumbers shrink during periods of aestivation and have naturally flaccid bodies that make measuring growth difficult. In this study, we obtained lengthfrequency data on Holothuria arguinensis, measuring undisturbed animals in situ, because it i...

Holothuria mammata is one of the new target species from the Mediterranean and Atlantic. Usually, it inhabits rocky bottoms, staying in crevices and holes during the day and leaving them in the night for feeding on sandy bottoms. However, it can be found in unusual habitats such as seagrass with diurnal and nocturnal feeding. This study provides in...

In salmonids, the release of hatchery-reared fish has been shown to cause irreversible genetic impacts on wild populations. However, although responsible practices for producing and releasing genetically diverse, hatchery-reared juveniles have been published widely, they are rarely implemented. Here, we investigated genetic differences between wild...

Ruppia cirrhosa is a clonal monoecious plant phylogenetically associated to seagrass families such as Posidoniaceae and Cymodoceaceae. It inhabits shallow waters that are important for productivity and as a biodiversity reservoir. In this study, we developed 10 polymorphic microsatellite loci for R. cirrhosa. Additionally, we obtained cross-amplifi...

Sexual selection theory predicts that, in organisms with reversed sex roles, more polyandrous species exhibit higher levels of sexual dimorphism. In the family Syngnathidae (pipefish, seahorses, and seadragons), males provide all parental care by carrying developing embryos on their ventral surfaces, and females develop secondary sex characters. Sy...

Coastal lagoons are dynamic ecosystems characterized by vigorously changing temporal and spatial conditions. They are an intriguing field for the study of genetic adaptations and community behavior. In these ecosystems, a small number of species is able to tolerate these conditions. Polychaetes are one of the most abundant taxa inhabiting lagoons a...

Environmental heterogeneity in coastal lagoons is expected to facilitate local adaptation in response to different ecological conditions, causing significant genetic structuring within lagoon populations at a small scale and also differentiation between lagoons. However, these patterns and processes of genetic structuring are still poorly understoo...

The population status of Holothuria arguinensis in Ria Formosa (southern Portugal) was assessed using a visual census conducted by a volunteer programme, the CUMFISH project. We found high densities of this species (267 ± 152 ind. ha-1) in Praia de Faro, but the values oscillated, depending on transect and habitat. H. arguinensis seems to prefer a...

In the last years, bioinvasions are increasing their ecological and economic impacts on different habitats all over the world, and are therefore becoming the target of much recent research (Ricciardi et al., 2004; Bernardi et al., 2010; Zenetos et al., 2012). The leading hypothesis for the origin of invasions is that colonization by invasive specie...

Brackish water ecosystems are often exposed to wide variations in environmental variables, including temperature and salinity, which may cause strong selective pressures on organisms modifying the genetic patterns of species. The aim of this work was to test whether there is a ‘divergence‐with‐gene flow’ in coastal lagoon populations of white seabr...

Human exploitation has drastically reduced the abundance and distribution of several marine fish and invertebrate populations through overfishing and habitat destruction. Restocking can potentially mitigate these impacts and help to reconstitute depleted stocks but genetic repercussions must be considered. In the present study, the degree of geneti...

Sea cucumber stocks have been overfished in many countries from Indian and Pacific oceans as result of ever-increasing market demand, uncontrolled exploitation and/or inadequate fisheries management. The life-history traits of holothurians make them especially vulnerable to overfishing because they have low or infrequent recruitment, high longevity...
