“…The present results corroborate the findings of Malavasi et al (2004), in which the estuarine residents comprise about 50% of the fish community of the Venice Lagoon. Unlike larger estuaries, marine juvenile migrant species (MJ) were less important in both number of species and total densities.…”

“…When comparing with other European estuarine systems (e.g. Laffaille et al, 2000;Cabral et al, 2001;Gordo and Cabral, 2001;Potter et al, 2001;Costa et al, 2002;Hampel et al, 2003;Malavasi et al, 2004), the main difference that can be found is the absence of Mugilidae as one of the most important families. Beam trawling is often considered a suitable method for sampling benthic species, but tends to underestimate pelagic species (Thiel et al, 2003) such as mugilids.…”

As outlined by Martinho et al (2007), seasonal abundance peaks for these species were recorded, and directly linked to the seasonal patterns of recruitment and migration between enclosed and coastal waters.…”

“…In this lagoon, benthivorous species (BV) were also dominant in the fi sh assemblage in terms of both species number and abundance. Similar fi sh assemblage in the Venice Lagoon was observed, with resident (R) group being the most represented, both in number of species and fi sh abundance (Malavasi et al 2004, Franco et al 2006.These results contrast with many other studies conducted in European lagoons. Franco et al (2008) Table 1 for species labels were dominated in general by marine species and detritivorous and omnivorous fi sh.…”

R. 2015. Fish assemblages of a shallow Mediterranean lagoon (Nador, Morocco): An analysis based on species and functional guilds. Acta Ichthyol. Piscat. 45 (2): 115-124.Background. Due to their location between the continent and the sea and their shallow depths, lagoons play an important ecological role in coastal ecosystems by providing a selection of habitat types for many species, functioning as nursery areas and feeding grounds for marine opportunistic fi shes. The fi sh fauna of the Nador Lagoon (NE Morocco), as in the majority of southern Mediterranean lagoons, has been insuffi ciently studied, even though the lagoon itself supports important commercial fi sheries. The presently reported study investigated the spatial and seasonal uses of shallow habitats for fi sh fauna in the Nador Lagoon. Materials and methods. Sampling was done using a beach seine net at six stations covering almost entire lagoon and representing habitats differing in many parameters such as the distance from the inlet, bottom sediment characteristics, presence of macroalgae, etc. The fi sh abundance was standardized as catch per unit effort (CPUE) and the fi sh community was analysed both in terms of its taxonomic and functional composition (by making use of both ecological and dietary preference guilds). Results. A total of 2872 individuals, representing 15 species from 12 families, was collected during the four seasons. Only six species were always present in all seasons. Fish abundance peaked in spring and the species diversity was higher in spring and summer. The fi sh assemblage was largely dominated in terms of ecological guild by the resident and benthivorous species. Spatial and seasonal fi sh assemblages differed both in terms of fi sh abundance and diversity and also in terms of functional guilds composition. In autumn, the fi sh assemblage was dominated by the marine juvenile migrants whereas in winter, spring, and summer, resident species were the most abundant. Conclusion. The combination of taxonomic and functional characteristics of the fi sh assemblages, determined in the presently reported study, may contribute to a better understanding of the ecological networks of the Nador Lagoon, thus providing useful data for its conservation and management. Keywords: fi sh, spatio-temporal assemblages, beach seine, lagoon, Nador, Morocco Jaafour et al. 116 or even restoring certain Mediterranean lagoons are being discussed. Hence, there is a need for more information on the role and functioning of coastal lagoons in terms of fi sh requirements.The Nador Lagoon, also known as the "Sebkha Bou-Areg" or "Mar Chica" (the small sea), is the second largest lagoon complex in northern Africa (115 km 2 ) and the broadest paralic environment of Morocco. Its importance consists not only in its ecological value (RAMSAR site) but also in its socio-economic role. The fi sh fauna of the Nador Lagoon is not well known (Bouchereau et al. 2000), although the lagoon itself maintains a diverse fi sh community and supports important commercial ...

“…Of the numerous gobiine species found in the Mediterranean area, the marbled goby Pomatoschistus marmoratus (Risso, 1810) is one of the most abundant benthic fishes, inhabiting the sandy shallows of various estuaries and costal lagoons (Fouda et al, 1993;Koutrakis et al, 2000;Malavasi et al, 2004;Verdiell-Cubedo et al, 2007;Berrebi et al, 2009). This goby is widespread throughout the eastern Atlantic, Mediterranean, Black and Azov seas and Suez Canal (Miller, 1986), and it has a small-body which reaches a maximum total length of 65 mm (Miller, 1986).…”

a b s t r a c tThe marbled goby Pomatoschistus marmoratus, a species inhabiting coastal Mediterranean lagoons, has been studied by measuring its mitochondrial DNA variation. This analysis revealed a Mediterranean west vs east split and, subsequently, an eastern differentiation among the Libyan-Tunisian Gulf, the Adriatic Sea and the Aegean Sea. The high cohesion between the samples collected in the vast area of western Mediterranean contrasts with the genetic mosaic of the more sub-structured eastern Mediterranean. This western homogeneity can not yet be fully explained even if a human-mediated migratory flow, due to a maritime traffic, has been posited. The pattern in the eastern basin revealed a genetic architecture possibly due to the non-migratory habit of the gobid. Within this perspective, the role of the Mediterranean lagoon habitat should be related to how much it amplifies the effects of historical (e.g. past sea-level changes) and environmental (e.g. present-day hydrographic regime) processes as regards the genetic structure of the inhabiting species.
