Introduction
My research aims to improve the state of knowledge and general understanding of key species within marine ecosystems. These works are part of a current issue of assessing the impact of human activities, such as exploitation and pollution, on iconic species with important economic interest, in a context of climate change.

Article
Coastal harbor areas are subjected to a myriad of contamination sources with largely unknown effects. Such complex chemical mixtures are difficult to monitor but transcriptomics is a promising approach for such biomonitoring. The present study was designed to verify the use of the Coastal Biosensor for Endocrine Disruption (C-BED) assay, previously...
Article
The Eastern Corsican Coast (ECC) is distinguished by its shallow sandy shelf, extensive Posidonia seagrass meadows, and the relatively limited exploitation of fish in this region. To understand ECC trophic functioning and the effects of fishing in this region of the Mediterranean Sea, we applied the Ecopath and EcoTroph approaches. Our model encomp...

Health councils recommend a higher consumption of aquatic resources because of the health benefits associated with these kinds of food. Due to its nutritional quality, fish derived from marine environment is one of the major contributors to a healthy human nutrition. This study aims to assess the fatty acid profile and nutritional composition of cu...

Coastal port areas are subjected to a myriad of pollution sources. Contaminants in such systems include legacy pollutants (metals and hydrocarbons) and emerging contaminants (e.g. pharmaceuticals) with largely unknown effects. Monitoring for such complex chemical mixtures in marine ecosystems is difficult. Transcriptomics is a promising approach ap...

Les pollutions présentes en mer (organiques et inorganiques), proviennent à plus de 80% du domaine terrestre et des activités humaines qui y sont menées. Les eaux côtières, regroupant pas moins de 90% de la biodiversité marine, sont directement impactées par ces pressions anthropiques. Plus particulièrement, les zones portuaires, qui abritent bons...
Article
Small-scale fishery represents 83% of the Mediterranean fleet. Yet, its evaluation is made difficult by a scattered fishing effort, especially on large islands with remote fishing harbours. Corsica is considered as one of the area with the lowest fishing pressure in the Mediterranean and is mainly characterized by a small-scale fishery (SSF). The p...

Le biomonitoring du milieu marin, mis en place pour caractériser l’état écologique d’un milieu, ou évaluer les effets des protocoles de gestion environnementale, permet le développement d'une compréhension scientifique de l'environnement marin et des impacts des humains sur celui-ci. Les méthodes traditionnelles de biomonitoring sont généralement b...

Dans les zones portuaires, les divers polluants retrouvés dans le milieu constituent une menace sérieuse pour le milieu marin et les espèces qui y résident [1]. Les activités récréatives, le trafic maritime, le carénage, etc. provoquent une contamination qui s'ajoute à celle déjà observée en zone côtière. Ces pressions anthropiques chroniques peuve...
Chapter
Human activities, whether at sea, on land or along the human‐made coastline may cause chronic and diffuse pollution in the marine environment that represents 75% of the global marine pollution. The use of bioindicators is particularly relevant from a biological point of view if the directly measured concentrations reflect the bioavailable fractions...

Coastal fishes are not only valuable elements of marine biodiversity, but they also play an important ecological role in the functioning of coastal ecosystems: food resource, transfer of nutrients, predators. Therefore, data on the compositions of fish assemblages are of great importance. The objectives of the present study were to (i) define the f...

Les zones portuaires sont des socio-écosystèmes anthropisés soumis à l’influence des bassins versants et à une forte urbanisation. Ces environnements semi-fermés sont impactés par des polluants (organiques et inorganiques) liés à la dynamique spécifique des ports (trafic maritime, activités de pêche, plaisance, peintures antisalissures). Malgré ces...

Marine aquaculture provides undoubted economic benefits and diverts a proportion of fishing pressure on wild stocks. However, it is known to strongly impact marine life with the Mediterranean region, which is densely populated and urbanized with a strong demand for seafood, especially sensitive to marine aquaculture pressures. Marine aquaculture no...

Although Argyrosomus regius (Asso, 1801) counts among the most appreciated and increasingly consumed fish species in Europe, little information is available on its flesh quality. This research concerns both healthy aquatic resource diversification and good nutritional quality. It is the first study to evaluate the quality of A. regius flesh from Me...

The common spiny lobster (Palinurus elephas, Fabricius, 1787) is an iconic species of the Mediterranean Sea. Despite the existence of data on the artisanal fishery of P. elephas in the Mediterranean Sea and particularly in Corsica, knowledge on the biology and life history traits of this iconic species is still lacking. This paper identifies the ma...

Coastal areas are the interface between terrestrial and marine ecosystems and are a habitat for 90% of the marine biodiversity. However, these waters are the first impacted by anthropic activities, especially in port areas, due to the maritime traffic or accidental pollution. Following the recommendations of the Marine Strategy Framework Directive,...

The current study examined the concentrations of ten trace elements (TE) (nickel, chromium, cadmium, iron, zinc, manganese, aluminum, copper, selenium and lead) in the edible tissue of the Ark shell Arca noae (L. 1758) from a Mediterranean coastal lagoon, the Bizerte lagoon during 2013–2014. The analysis of several redox status biomarkers, metallot...

Marine litter is a widespread problem affecting all the oceans of the world. Plastics represent around 90% of marine litter, and it is estimated that there are between 15 and 51 trillion plastic particles floating on the surface of the oceans. The objectives of this study are to: (i) identify and characterize the main categories of floating items s...

Swordfish (Xiphias gladius L., 1758) is an apex predator, highly migratory meso-pelagic fish widely distributed in the Atlantic Ocean and Mediterranean. As top predators, this fish may be the end reservoir of the bioaccumulation of trace elements in a food chain because they occupy higher trophic levels and are an important food source, causing the...

Three methods of age estimation were compared for Dentex dentex. Based on sectioned otoliths, scales appeared to be relevant only up to 5 years and whole otoliths up to 12 years. The maximum estimated age was 36 years, which constitutes to date the oldest age reported.
