“…Their habitat structure characteristics explain these differences (García‐Charton et al., 2004). While rocky bottoms concentrate bigger adult individuals, P. oceanica harbours predominantly juveniles and adults of small sized species and also works as a transitional habitat and shelter for early‐stage larvae of fishes (Del Pilar Ruso and Bayle‐Sempere, 2006). However, in relative terms differences between protected and unprotected meadows were similar to those obtained in studies carried out on rocky bottoms.…”

This study describes the changes in the structure of the fish assemblage associated with Posidonia oceanica meadows after the establishment of a marine protected area. The survey of the ichthyofauna in the Marine Reserve of Tabarca Island was carried out by visual censuses with SCUBA. Inside and outside the reserve was sampled six times at random from summer 1997 to summer 1999 and in three different depths (1, 5 and 15 m) by applying transects of 150 · 5 m over the P. oceanica meadows. The data were analyzed with multivariant methodologies and with analysis of variance. The most represented families in number of species were the sparids and labrids. Mean abundance, biomass and number of species were higher inside the reserve in all studied periods. Inside the marine protected area, these variables decreased as depth increased; outside the protected area the pattern was the opposite, reaching the maximum at 15 m.

“…We included both characteristic species and regular visitors in this evaluation. In the second case, we considered the species that visits the meadows on an occasional but regular basis, such as nocturnal hunters, and those that usually live in patchy meadow areas were also included [43,44]. Fishery data used in this study were provided by the "Sailors and Shareholders cooperative", which manages the fish auctions in the Civitavecchia area and brings together thirteen of the sixteen fishing boats that make up the fleet of Civitavecchia, which regularly operates in the study area.…”

A Benthic Zonation System as a Fundamental Tool for Natural Capital Assessment in a Marine Environment: A Case Study in the Northern Tyrrhenian Sea, Italy

et al. 2018

Coastal marine areas are characterized by the highest values of ecosystem services and by multiple uses that are often in conflict with each other. Natural capital analysis is claimed to be a valid tool to support space planning. In the context of the Marine Strategy Framework Directive (MSFD) of the European Union (EU), the EU Joint Research Centre (JRC) Scientific and Policy Report 2014 defines the monitoring of specific descriptors and their possible use, based on an ecosystem-services approach. Mediterranean marine ecosystems are characterized by high biodiversity and the presence of relevant benthic biocenosis that can be used as a tool to support coastal planning, conservation, and monitoring programs. In this study, we considered the Mediterranean benthic biocenosis, as classified by Pérès and Picard, as a working tool and propose a basic spatial unit for the assessment of marine ecosystem services. Focusing on a high-resolution local-scale analysis, this work presents an accurate identification of the different biocenoses for the coastal area of Civitavecchia in the Northern Tyrrhenian Sea, Italy, and ecosystem services, as well as a benefits assessment, of the Posidonia oceanica meadows.

The influence of physical and biological processes on the ichthyoplankton communities in the Gulf of Sirte (Southern Mediterranean Sea)

et al. 2016

This paper reports on the first study on the ichthyoplankton community structure in the Gulf of Sirte and its spatial distribution in relation to environmental conditions and zooplankton abundance. The results make an important contribution to the future management of fisheries in this unexplored, but much exploited, area. Biological samples were collected in July 2008 using a Bongo40 net. In total, 1914 larvae were found and 1652 of these were identified. In particular, bathypelagic taxa were the most abundant, followed by demersal, mesopelagic, pelagic and epipelagic taxa. The ichthyoplankton community had a patchwork distribution influenced by oligotrophic conditions, the bottom depth and oceanographical features. The results suggest that environmental forcings were able to transport the ichthyoplankton to productive areas. Indeed, maximum fish egg densities were found in coastal stations in correspondence with the Atlantic Tunisian Current inflow, whereas larvae were mainly concentrated in the east side of the Gulf, probably as a result of advection by the anticyclonic circulation. Additionally, the distribution patterns of the total larvae density and the different assemblages were well matched with the abundance of the zooplankton, probably determining final larval survival, growth and recruitment.
