Functional groups are sets of species that play a similar role in a food web. We defined functional groups of fish species based on their morphological characteristics, while using expert knowledge for invertebrates. We measured 9 morphological traits of 72 fish species, and carried out multivariate analyses to assign fish species to functional groups. The analysis identified 9 trait-based fish functional groups to which were added 3 expert-based invertebrate functional groups. The habitat (position in the water column) and potential diet of each group were identified from the literature. Using the MEDITS bottom trawl survey data collected at 10 to 800 m depth, we calculated relative change in the 12 fish and invertebrate functional group biomasses for 12...

The uncertainty in age estimation by otolith reading may be at the root of the large variability in red mullet (Mullus barbatus) growth models in the Mediterranean. In the MEDITS survey, red mullet age data are produced following the same sampling protocol and otolith reading methodology. However, ageing is assigned using different interpretation schemes, including variations in theoretical birthdate and number of false rings considered, in addition to differences in the experience level of readers. The present work analysed the influence of these variations and the geographical location of sampling on red mullet ageing using a multivariate approach (principal component analysis). Reader experience was the most important parameter correlated with the...

Investigation of spatiotemporal patterns in mean temperature and mean trophic level of MEDITS survey catches in the Mediterranean Sea ArchiMer
Peristeraki, Panagiota; Bitetto, Isabella; Carbonara, Pierluigi; Carlucci, Roberto; Certain, Gregoire; De Carlo, Francesco; Gristina, Michele; Kamidis, Nikos; Pesci, Paola; Stagioni, Marco; Valls, María; Tserpes, George.
Mean temperature (MTC) and mean trophic level (MTL) spatiotemporal patterns of MEDITS survey catches were examined in 13 geographic statistical areas (GSAs) of the Mediterranean between 1994 and 2016. The study aimed to detect changes in the demersal community structure related to anthropogenic impacts. A generalized additive modelling approach was used to examine the effects of year and GSA on the MTC and MTL indexes and on bottom temperature by haul. For the MTC index, the year was significant only in 4 GSAs, while for MTL it was significant in 5. Higher MTC values were observed in central and eastern areas. Bottom temperature increased after 2010, and also from west to east and from north to south. Our results indicate that the recently observed...

Increasing human pressures and global environmental change may severely affect the diversity of species assemblages and associated ecosystem services. Despite the recent interest in phylogenetic and functional diversity, our knowledge on large spatio-temporal patterns of demersal fish diversity sampled by trawling remains still incomplete, notably in the Mediterranean Sea, one of the most threatened marine regions of the world. We investigated large spatio-temporal diversity patterns by analysing a dataset of 19,886 hauls from 10 to 800 m depth performed annually during the last two decades by standardized scientific bottom trawl field surveys across the Mediterranean Sea, within the MEDITS program. A multi-component (eight diversity indices) and...

The data come from organisms and pictures collected during the MEDITS annual bottom trawl surveys conducted between 2011 and 2013 (Bertrand et al. 2002). MEDITS surveys cover the continental shelf (10 m to 200 m depth) and the upper part of the continental slope (200 m to 800 m) on the Mediterranean. A total of 1511 individuals from 85 fish species were collected from seven Mediterranean areas (South Adriatic Sea, Sardinia, Gulf of Lions, around Cyprus, Mallorca, Tyrrhenian Sea, and North West Ionian Sea). A set of 14 morphological traits related to the habitat and the diet of the species were measured in the field and on pictures using the ImageJ software (version 1.47, http://imagej.nih.gov/ij/) (see Granger et al. 2015 and Brind'Amour et al. submitted...

Mahe, Kelig; Elleboode, Romain; Charilaou, Charis; Ligas, Alessandro; Carbonara, Pierluigi; Intini, Simona.
There were an exchange and a workshop in 2009 of Red mullet Mullus barbatus and Striped red mullet Mullus surmuletus (WKACM). The Otolith Exchange Scheme 2011 was the second exercise for the Red mullet Mullus barbatus and Striped red mullet Mullus surmuletus. 5 readers participated in this exchange. The images collection (n=540) came from the Bay of Biscay, the Balearic Islands, the Southern Spain and the Southern Adriatic sea. 175 Mullus surmuletus and 202 Mullus barbatus have been examined to all Institutes. Among 540 images, there were 377 otoliths and 163 scales. 2 images sets have been realised for Mullus surmuletus in Balearic Islands and for Mullus barbatus in the Southern Spain to compare the age estimation between both calcified pieces.

Marine litter is one of the main sources of anthropogenic pollution in the marine ecosystem, with plastic representing a global threat. This paper aims to assess the spatial distribution of plastic macro-litter on the seafloor, identifying accumulation hotspots at a northern Mediterranean scale. Density indices (items km–2) from the MEDITS trawl surveys (years 2013-2015) were modelled by generalized additive models using a Delta-type approach and several covariates: latitude, longitude, depth, seafloor slope, surface oceanographic currents and distances from main ports. To set thresholds for the identification of accumulation areas, the percentiles (85th, 90th and 95th) of the plastic spatial density distribution were computed on the raster data. In the...

Thanks to the availability of the MEDITS survey data, a standardized picture of the occurrence and abundance of demersal Chondrichthyes in the northern Mediterranean has been obtained. During the spring-summer period between 2012 and 2015, 41 Chondrichthyes, including 18 sharks (5 orders and 11 families). 22 batoids (3 orders and 4 families) and 1 chimaera, were detected from several geographical sub-areas (GSAs) established by the General Fisheries Commission for the Mediterranean. Batoids had a preferential distribution on the continental shelf (10-200 m depth). while shark species were more frequent on the slope (200-800 m depth). Only three species, the Carcharhiniformes Galeus melastomus and Scyliorhinus canicida and the Torpediniformes Torpedo...

Spatiotemporal abundance pattern of deep-water rose shrimp, Parapenaeus longirostris, and Norway lobster, Nephrops norvegicus, in European Mediterranean waters ArchiMer
Sbrana, Mario; Zupa, Walter; Ligas, Alessandro; Capezzuto, Francesca; Chatzispyrou, Archontia; Follesa, Maria Cristina; Gancitano, Vita; Guijarro, Beatriz; Isajlovic, Igor; Jadaud, Angelique; Markovic, Olivera; Micallef, Reno; Peristeraki, Panagiota; Piccinetti, Corrado; Thasitis, Ioannis; Carbonara, Pierluigi.
The main characteristics concerning the distribution of two of the most important decapod crustaceans of commercial interest in the Mediterranean Sea, the deep-water rose shrimp, Parapenaeus longirostris, and the Norway lobster, Nephrops norvegicus, are studied in the European Mediterranean waters. The study is based on data collected under the MEDITS trawl surveys from 1994 to 2015 from the Gibraltar Straits to the northeastern Levantine Basin (Cyprus waters). The observed differences can be interpreted as different responses to environmental drivers related to the differing life history traits of the two species. In fact, N. norvegicus is a long-living, benthic burrowing species with low growth and mortality rates, while P. longirostris is an epibenthic,...

Spatio-temporal trends in diversity of demersal fish assemblages in the Mediterranean ArchiMer
Farriols, M. Teresa; Ordines, Francesc; Carbonara, Pierluigi; Casciaro, Loredana; Di Lorenzo, Manfredi; Esteban, Antonio; Follesa, Cristina; García-ruiz, Cristina; Isajlovic, Igor; Jadaud, Angelique; Ligas, Alessandro; Manfredi, Chiara; Marceta, Bojan; Peristeraki, Panagiota; Vrgoc, Nedo; Massutí, Enric.
The high species richness, coupled with high proportion of endemism, makes the Mediterranean one of the world’s ‘biodiversity hotspots’. However, the continuous increase in fisheries in the last few decades has led to the overexploitation of their main commercial stocks. Using fishery-independent data collected under the framework of the MEDITS trawl surveys carried out over the last 20 years, we study the demersal fish diversity pattern in the Mediterranean at a large spatial and temporal scale to determine whether it is being affected by the general fishing overexploitation of the demersal resources. The detected diversity trends are compared with the spatio-temporal variation in bottom trawl fishing effort in the Mediterranean. Our results show a...

Spatio-temporal variability in the distribution pattern of anglerfish species in the Mediterranean Sea ArchiMer
Barcala, Helena; Bellido, Jose Maria; Bellodi, Andrea; Carbonara, Pierluigi; Carlucci, Roberto; Casciaro, Loredane; Esteban, Antonio; Jadaud, Angelique; Massaro, Andrea; Peristaki, Panagiota; Melendez, Maria Jose; Perez Gil, José Luis; Salmeron, Francisca; Pennino, Maria Grazia.
The Mediterranean distributions of two species of anglerfish, the blackbellied anglerfish (Lophius budegassa) and the white anglerfish (Lophius piscatorius), were analysed from trawl survey data (MEDITS project – Spain, France, Italy and Greece) from 2006 to 2015 implementing a Delta model approach with residuals autocovariate boosted regression trees. Sea bottom temperature (SBT), sea bottom salinity (SBS), bathymetry, slope of the seabed and distance to the coast were considered possible predictors. The results show that the locations with a higher presence, abundance and biomass of L. budegassa are those with a depth range between 150 to 300 m, with an SBT range between 17.5 and 18.5°C, and SBS of 37-38 PSU. Similarly, L. piscatorius shows a higher...

Trawling pressure and environmental changes may affect the composition of fish assemblages. Our knowledge on large spatio-temporal patterns of demersal fish composition remains incomplete for the Mediterranean Sea. We investigated (1) the spatio-temporal stability of demersal assemblages, (2) the relationships between these assemblages and potential structuring factors (trawling pressure and environmental conditions) in order to assess the dynamic of the assemblage structure at the scale of the northern Mediterranean Sea. We analysed a dataset of 18062 hauls from 10 to 800 m depth performed annually during the last two decades across 17 Geographical Sub-Areas (GSAs) (MEDITS program). A multi-table analysis (STATICO-CoA) evidenced a strong inter-GSAs...

Understanding the Population Structure of the European Anchovy (Engraulis encrasicolus) in the Black Sea, Mediterranean Sea and Northeast Atlantic Ocean by Using Otolith Shape Analysis ArchiMer
Akkus, Gizem; Jemaa, Sharif; Cemal Gucu, Ali; Marchal, Paul; Carbonara, Pierluigi; Bacha, Mahmoud; Amara, Rachid; Ernande, Bruno; Saraux, Claire; Mahe, Kelig.
European anchovy, Engraulis encrasicolus, is a small pelagic coastal marine fish largely spread from the North Sea to central Africa, including the entire Mediterranean and the Black and Azov Seas. The aim of the study is to understand the potential different population structure and their relationship between the Northeast Atlantic, Western, Eastern Mediterranean and the Black Sea anchovy population. The outlines of 2127 sagittal otoliths were collected from nineteen locations (English Channel, Atlantic, the Mediterranean and Black Sea), and added to existing information available from a previous study. Elliptical Fourier Analysis (EFA) was used to analyze the otolith shape variations among locations. Before examining the geographical differentiation by...
