“…The highest values of biomass in summers and autumns are correlated to the existence of Cymbium cucumis known by its large body and the absence of this species in winter highly decreases the biomass values. Some studies, investigated the vertical distribution of biomass in the sediment, so they found that biomass was higher in sediments deeper than 15 cm as a consequence of larger individual sizes living deeper like C. cucumis (Celentanoa et al, 2019) Bayed (1991) found that all the benthic communities are occupied mainly by crustaceans (C>P-M). A total of 13,313 specimens were collected across the 39 beaches in north of Spain.…”

“…The aim of this work was to assess the initial state of the macrozoobenthic biodiversity, which is one of the best biological tools that estimate the environmental change affecting ecosystems (Le Bris et al, 1996). The benthic macro-fauna plays a key role in the characterization and the functioning of the littoral ecosystems and constitutes a good indicator of their health (Chaouti et al, 2005;Gonzalez et al, 2014;Celentanoa et al, 2019). It is so closely correlated to the ecological conditions, which prevail in the interface water-sediment (Bayed, 2003;Lefrere et al, 2015).…”

The region of Agadir has experience considerable development for a few years with numerous anchor projects for the various sectors (fishing, tourism, industry, agriculture etc.). Large parts of these development projects are located on the coast. As an example, a new large sea resort called Taghazout Bay (615 ha) is located on the shoreline of Taghazout, about fifteen kilometers from the Agadir city. This tourist project may provoke disturbances on the faunal and floral organizations, as well as on the physico-chemical quality of the seawater and the sediment. Besides the recent study on the microbiological quality of the Taghazout seawater (Lamine et al., 2019) and the study of Donax trunculus dynamics (Lamine et al., 2020), to our knowledge, no ecological study was realized at the coasts of Taghazout. In fact, the studies on the sandy beaches at the regional and national level are still rare. Otherwise, one

“…It has been accepted that sandy beach macroinfauna is regulated by hydrodynamic processes, such as tides and swash climates, and the associated beach morphological characteristics, including sediment grain size, beach length and beach-face slope (Brazeiro, 2005;Cardoso & Veloso, 2003;Colombini et al, 2002;Defeo & McLachlan, 2005;Jaramillo, McLachlan, & Dugan, 1995;Lastra et al, 2006;Lozoya, Gómez, & Defeo, 2010;McLachlan, 1990;McLachlan & Defeo, 2018;Scapini, 2014;Schlacher & Thompson, 2013). The associated gradients/ variations of abiotic environments, such as water content, sediment temperature, pH and sediment hardness/compaction of surficial sediments are known to affect the distributions of sandy beach macroinfauna (Celentano et al, 2019;Jaramillo, McLachlan, & Coetzee, 1993;Pavesi, Iannilli, Zarattini, & De Matthaeis, 2007;Sassa & Yang, 2019a;Scapini, Degli, & Defeo, 2019;Tsubokura, Goshima, & Nakao, 1997). Relatively few studies have examined how changes in the geophysical environments can exert control on the distributions and diversity of sandy beach macroinfauna.…”

Recently, it has been shown that suction, which means the tension of moisture in sediments, is responsible for the distribution limits of the amphipods Haustorioides japonicus and Trinorchestia trinitatis and the isopod Excirolana chiltoni. Such effects take place through three distinctive suction‐induced mechanisms, associated with burrowing, physiology and the stability of burrows. Based on this background, in this study, we investigated storm‐induced morphological changes in beach profiles and the associated variations in geoenvironments, namely the suction, the degree of saturation, water content and sediment hardness, of the sandy beach habitats. The associated changes in cross‐shore distributions of the three peracarid crustaceans were also investigated. Field studies were carried out before and after monsoonal storms at two sandy beaches, Maze and Gokahama, located on the Japan Sea coast in Niigata Prefecture, Japan. The results showed that the suction‐induced variations of the geophysical environments were universal, irrespective of the storm‐induced morphological changes in the beach profiles. In addition, there were distinct changes in the cross‐shore distributions of the peracarid crustacean populations, associated with the storm‐induced morphological changes. The variations in the developed suction consistently and quantitatively accounted for these distinct changes in the cross‐shore distributions of the peracarid crustaceans, associated with the event‐induced morphological changes. Hence, suction played a crucial role as a key geoenvironmental variable in determining the distribution changes of the three peracarid crustaceans studied, even following the event‐induced morphological changes of the beach profiles.

“…La almeja amarilla Mesodesma mactroides es un molusco bivalvo infaunal habitante de la zona intermareal en playas de la costa Atlántica de América del Sur, desde Santos (Brasil, 24º S) hasta Río Negro (Argentina, 41º S) (Fiori y Morsán, 2004). M. mactroides vive enterrada en la arena en posición vertical a profundidades mayores a los 10,0 cm (Celentano, et al, 2019), preferentemente en la zona intermareal de playas disipativas, un ambiente rico en nutrientes y oxígeno, pero a la vez dinámico. En Uruguay, la pesca artesanal de M. mactroides se desarrolla en una franja de costa de 22 km de extensión entre la Coronilla y Barra de Chuy (Gianelli, et al, 2015).…”

Bivalve mollusks are important aquaculture and fisheries resources. On the Atlantic coast of Uruguay, the yellow clam Mesodesma mactroides has been traditionally exploited by hand. In recent years, its consumption has been notoriously valued, becoming a gastronomic product for regional restaurants. To obtain a quality product, a process of sand purification is carried out, keeping the clams in seawater tanks for short periods. However, there is no knowledge about the effects of this process or an analysis of the optimal conditions of purification. The goal of this paper was to experimentally evaluate several techniques that allow keeping M. mactroides state under laboratory conditions. Survival tests were performed to evaluate labeling, diets, types of artificial marine water (AMW), anatomical position of the organisms in captivity and substrate. The results showed that survival was not affected by the marking method and the legibility of the labels was not altered. Dry Spirulina was adequate as an alternative diet. The AMW of simpler composition and lower cost significantly increased survival after the first week of experimentation. Keeping individuals upright significantly increased survival compared to a horizontal position. These results have immediate applicability, contributing in the medium term to the development of the species in captivity.
