Age et croissance de l'oursin Paracentrotus lividus Lamarck, 1816 (Echinodermata-Echinoidea) dans le golfe de Tunis (Méditerranée) ArchiMer
Sellem, Fériel; Langar, Habib; Pesando, Danielle.
The age of Paracentrotus lividus in the gulf of Tunis was evaluated by analysing the natural growth banding in the interambulacral plates from the oral part of the test. It appeared that growth rates increased in spring and summer, and decreased in autumn and winter. The maximum age and diameter were estimated to be 8 years and 53 mm respectively, Compared to populations of Paracentrotus lividus from NW Mediterranean and Atlantic, that of the gulf of Tunis presented a more rapid growth.

Analyse de l’activité de pêche aux filets maillants dérivants de moins de 2,5 km en Méditerranée et caractéristiques techniques des engins ArchiMer
Sacchi, Jacques; Lespagnol, Patrick.
Suite à l'interdiction communautaire d'utiliser des filets dérivants (définis selon le règlement CE N° 809/2007) pour la capture des espèces citées dans l'annexe VIII du règlement 1239/98 (modifiant le règlement 894/97) la pratique de cette technique se trouve actuellement limitée à un nombre réduit de métiers utilisés saisonnièrement par la flottille de petite pêche française de Méditerranée, des côtes du Roussillon à celles de Corse. Ces métiers ciblant principalement des sparidés, du bar et quelques petits pélagiques utilisent des filets maillants de surface ou de fond, soit calés au moyen de lignes de mouillage soit en dérive amarrés au navire. Une grande partie des informations sur l’activité de pêche en Méditerranée des filets maillants provient des...

Balneola vulgaris gen. nov., sp nov., a member of the phylum Bacteroidetes from the north-western Mediterranean Sea ArchiMer
Urios, Laurent; Agogue, Hélène; Lesongeur, Francoise; Stackebrandt, Erko; Lebaron, Philippe.
A novel aerobic, Gram-negative bacterium, named 13IX/A01/164(T), was isolated from surface waters in the coastal north-western Mediterranean Sea. Cells were motile, straight rods, 2-5 mu m long and 0-2 mu m wide, and formed orange colonies on marine agar medium. The G+C content of the genomic DNA of strain 13IX/A01/164T was 42 mol%. Phylogenetic analysis of the 16S rRNA gene sequence placed the strain in the phylum Bacteroidetes within the family Crenotrichaceae. On the basis of 16S rRNA gene sequence comparison and physiological and biochemical characteristics, this isolate represents a novel species of a new genus, for which the name Balneola vulgaris gen. nov., sp. nov. is proposed. The type strain of Balneola vulgaris is 13IX/A01/164T (=DSM 17893T=CIP...

Vanreusel, Ann; Andersen, Ann C.; Boetius, Antje; Connelly, Douglas; Cunha, Marina R.; Decker, Carole; Hilario, Ana; Kormas, Konstantinos Ar.; Maignien, Lois; Olu, Karine; Pachiadaki, Maria; Ritt, Benedicte; Rodrigues, Clara; Sarrazin, Jozee; Tyler, Paul; Van Gaever, Saskia; Vanneste, Heleen.
During the European Commission's Framework Six Programme, HERMES, we investigated three main areas along the European margin, each characterized by the presence of seep-related structures exhibiting different intensity of activity and biological diversity. These areas are: (1) the Nordic margin with the Hakon Mosby mud volcano and many pockmarks, (2) the Gulf of Cadiz, and (3) the eastern Mediterranean with its hundreds of mud volcanoes and brine pool structures. One of the main goals of the HERMES project was to unravel the biodiversity associated with these seep-associated ecosystems, and to understand their driving forces and functions, using an integrated approach. Several multidisciplinary research cruises to these three areas provided evidence of...

C18 Sep-Pak extractable dissolved organic copper related to hydrochemistry in the North-West Mediterranean ArchiMer
El Sayed, Mohamed A.; Aminot, Alain.
Extractable organic copper using C18 Sep-Pak cartridges was investigated in seawater after laboratory experiment showed that the (C18 Sep-Pak) cartridges were reliable, in open and coastal waters with normal levels of dissolved organic carbon, for the separation of a specific fraction of organo-copper complexes.Given that the Sep-Pak cartridges retain the hydrophobic fraction of the dissolved organic matter, this extraction technique was applied for studying the characteristics of this particular hydrophobic dissolved organic copper fraction (hDOCu) in the north-western Mediterranean waters. Surface distribution of hDOC is influenced by organic matter input from the river Rhone and its estuary as well as the physical processes affecting the primary...

Donnees preliminaires sur les caracteres biometriques des anchois Engraulis encrasicolus (Linne, 1758) des cotes de Tunisie et du Lac Ichkeul ArchiMer
Quignard, J.p; Hamdouni, T; Zaouali, J.
Researchers have studied the number of rays in the dorsal and anal fins, the number of branchiospines and of vertebrae of the anchovies of the Tunisian coast. Regarding the number of vertebrae, the anchovies of the North West belong to the 'West Mediterranean' group and those of the North East and South East to the 'East Mediterranean' group, according to Fage's classification. The anchovies found in Lake Ishkeul are well individualised morphologically and biologically speaking and could be classified in the large group of the anchovies living in Mediterranean brackish waters; the number of their vertebrae is slightly inferior to that of the groups living in the neighbouring sea waters.

Eivissa slides, western Mediterranean Sea: morphology and processes ArchiMer
Lastras, Galderic; Canals, M; Amblas, D; Ivanov, M; Dennielou, Bernard; Droz, Laurence; Akhmetzhanov, A.
After obtaining full-coverage swath bathymetry data in 1995 and very high-resolution acoustic profiles in 2002, four slides at the Balearic Margin of the Eivissa Channel in the western Mediterranean Sea were revisited in 2004 when side-scan sonar data were collected using a MAK-1M deep-towed acoustic system. These new findings, higher in resolution than those for the swath bathymetry, show two main features previously undetected within these submarine landslides: (1) a series of step-forming inclined and detached slabs oriented perpendicular to the slide movement and located in the uppermost part of the slides, and (2) arcuate regular positive ridges oriented also normal to the slide movement and located in the depositional lobes of some of the slides. The...

Etude morphologique du loup Dicentrarchus labrax L. de la region de Sete ArchiMer
Barnabe, Gilbert.
Sampling of a population of D. Labrax was one with spear diving catches. Morphometric and meristic data were used to calculate a biometric index. This index showed that all the bass of the Sete area belong to Dicentrarchus labrax, even if they were black spotted on the upper part of the body. Morphology was slightly different according to sex, but sex determination was not always possible using morphometric data. This inshore population shows some morphological characteristics (branchiospine and lateral line scale number) different from the data collected on the same sp along the Maroc Atlantic coast by Gravier, 1961.

First report of goniodomin A production by the dinoflagellate Alexandrium pseudogonyaulax developing in southern Mediterranean (Bizerte Lagoon, Tunisia) ArchiMer
Triki, Habiba Zmerli; Laabir, Mohamed; Moeller, Peter; Chomerat, Nicolas; Daly-yahia, Ons Kefi.
The dinoflagellate Alexandrium pseudogonyaulax is widely distributed around the world including the Mediterranean waters. The objectives of this study were to determine the morphology and phylogenic affiliation of A. pseudogonyaulax strain isolated from Bizerte Lagoon (Mediterranean waters, Tunisia) and investigate its toxicity. Molecular analyses confirmed the morphological identification of the isolated strain (APBZ12) as A. pseudogonyaulax. Moreover, it showed that it is 100% identical with strains of this species found in New Zealand, Japan, China and North Sea (Norway and Denmark) suggesting that this species is cosmopolitan. Until now, no toxin studies have been conducted on fully characterized (morphologically and molecularly) A. pseudogonyaulax....

How can we quantify impacts of contaminants in marine ecosystems? The ICON project ArchiMer
Hylland, Ketil; Burgeot, Thierry; Martinez-gomez, Concepcion; Lang, Thomas; Robinson, Craig D.; Svavarsson, Jorundur; Thain, John E.; Vethaak, A. Dick; Gubbins, Matthew J..
An international workshop on marine integrated contaminant monitoring (ICON) was organised to test a framework on integrated environmental assessment and simultaneously assess the status of selected European marine areas. Biota and sediment were sampled in selected estuarine, inshore and offshore locations encompassing marine habitats from Iceland to the Spanish Mediterranean. The outcome of the ICON project is reported in this special issue as method-oriented papers addressing chemical analyses, PAH metabolites, oxidative stress, biotransformation, lysosomal membrane stability, genotoxicity, disease in fish, and sediment assessment, as well as papers assessing specific areas. This paper provides a background and introduction to the ICON project, by...

Indices of bluefin tuna (Thunnus thynnus thynnus) abundance derived from sale records of French purse seine catches in the Mediterranean sea ArchiMer
Labelle, Marc; Hoch, Thierry; Liorzou, Bernard; Bigot, Jean-louis.
Sampling operations are not routinely conducted in France to monitor the landings of bluefin tuna caught by purse seiners in the Mediterranean. The length, weight and age frequencies of bluefin caught by this fleet are predicted based on sale records, length-at-age and weight-length relations, trends in fishing and natural mortality rates, and other ancillary data. The resulting length frequencies are more accurate than those predicted by Liorzou and Bigot (1992) using a simpler algorithm, and are spread more evenly across adjacent size classes. Catch-per-unil-effort (CPUE) was expressed as the numbers of age 2 bluefin caught per successful seine fishing trip in the Gulf of Lions fall fishery. CPUE indices were computed by several methods, and compared to...
