Nous savions déjà que l’aire de répartition géographique des espèces exploitées allait être modifiée dans le futur à cause du réchauffement climatique, engendrant une redistribution des stocks halieutiques dans les mers et les océans. Mais quelle sera l’ampleur des changements attendus au niveau des captures potentielles ? Est-ce que toutes les régions seront autant touchées ou bien est-ce qu’il y aura des gagnants et des perdants ? Ces modifications vont-elles affecter de la même façon les différents engins de pêche ?

Des chercheurs de l’Université Côte d’Azur (UMR ECOSEAS), du Centre Scientifique de Monaco, du Laboratoire d’Océanographie de Villefranche et du Genoa Marine Center (Station Zoologique Anton Dohrn) se sont regroupés pour se pencher sur ces questions. Pour cela, ils ont modélisé, projeté et cartographié les changements attendus des captures halieutiques potentielles de différents engins de pêche, selon deux scénarios climatiques, tout au long du 21ème siècle. Pour la première fois, les scientifiques se sont focalisés sur la zone européenne et ont travaillés à l’échelle des Zones Economiques Exclusives (ZEE), afin de fournir des projections détaillées qui serviront à améliorer la gestion des pêcheries et à élaborer des stratégies d'atténuation et d'adaptation au changement climatique pour ce secteur. Les résultats de cette étude viennent d’être publiés dans la revue Science of the Total Environment1.

Les projections indiquent une évolution différente des captures en fonction des engins de pêche. En Méditerranée, les baisses projetées vont de −20 à −75% pour les captures au chalut pélagique et à la senne, de −50 à −75% pour les filets fixes et les casiers et dépassent −75% pour le chalut de fond. Certaines espèces emblématiques, comme le loup et la dorade royale pourraient voir leurs captures diminuer de 40 %, en moyenne sur l’ensemble de la Méditerranée.

Géographiquement, des divergences devraient apparaître et certains pays pourraient voir leurs captures diminuer significativement alors qu’il est probable que d’autres les voient augmenter. On peut notamment citer les pays du Sud et de l’Est de la Méditerranée, qui seront les plus touchés. Au contraire, les captures devraient, elles, augmenter en mer du Nord et dans l’Atlantique Nord-Est pour les espèces étudiées.

Limiter le réchauffement climatique à des valeurs intermédiaires (scénario de réchauffement modéré RCP4.5) pourrait limiter la diminution des captures halieutiques en Méditerranée d’en moyenne 22% par rapport à un réchauffement intense (RCP8.5). Ces résultats soulignent donc la nécessité de limiter le réchauffement climatique et d’élaborer des stratégies d'adaptation au changement climatique pour le secteur de la pêche.

Dans le cadre du projet Ecoméd, financé par la Région Sud et Université Côte d’Azur, Francesca Rossi, Benoit Derijard et Simona Bussotti, chercheurs au laboratoire ECOSEAS, en collaboration avec les élèves du Collège Matisse de Nice et Julie Borgese, illustratrice scientifique, ont conçu une bande dessinée originale et pédagogique sur les enjeux des banquettes de Posidonie sur nos plages méditerranéennes.

Grâce à des interventions en classe, une expérimentation scientifique sur le terrain, puis la création de la bande dessinée « En route ! Les secrets de la plage avec Sidonie », les collégiens ont pu comprendre l’importance de la Posidonie dans l’écosystème des plages et prendre conscience de l’importance de préserver la biodiversité marine.

Lors du Festival des Sciences de Nice qui s’est déroulé le samedi 15 octobre 2022, plusieurs exemplaires de la bande dessinée « En route ! Les secrets de la plage avec Sidonie » ont été remis à Mme Vanessa Ferdjani, enseignante et porteuse du projet pour le Collège Matisse, qui à son tour distribuera les exemplaires aux élèves de sa classe.

Un grand merci aux élèves, aux enseignants, aux partenaires et à toutes les personnes qui ont contribué à la mise en œuvre du projet Ecoméd et qui ont permis, par leur implication et leur intérêt, la création de cette BD !

Poisson-flûte noyé dans sa sauce échalotes citronnées, ceviche de poisson-lion et ses patacones (bananes frites), chaudrée aux raviolis farcis de poisson-lapin… Ces recettes d’espèces exotiques ne sont pas tirées d’une publicité de quelque destination tropicale. Produites par le laboratoire ECOSEAS (UMR7035 Université Côte d’Azur - CNRS), elles sont disponibles sur le site du projet CLIM-ECO² pour sensibiliser le grand public aux nouvelles espèces qui viennent de mer Rouge et qui prolifèrent dans les eaux méditerranéennes grâce à l’augmentation des températures. Elles ont comme objectif d’encourager la consommation de ces poissons et lutter d’autant plus contre leur prolifération.

Selon Virginie Raybaud, Maître de Conférences à Université Côte d’Azur, interrogée par le journal de l’écologie Reporterre, ces poissons exotiques représentent un sérieux risque dans les années à venir pour les écosystèmes du nord-ouest de la Méditerranée (https://onlinelibrary.wiley.com/doi/abs/10.1111/gcb.15896).

Dans le cadre d’une collaboration entre le laboratoire ECOSEAS, le Centre Scientifique de Monaco et les UMR BOREA et LOG, un groupe de chercheurs vient de publier une nouvelle étude qui porte sur l’impact du réchauffement climatique sur la distribution géographique de certaines espèces de poissons méditerranéens à haute valeur économique. Sous l’effet de l’augmentation des températures, les espèces marines seront amenées à modifier leur aire de répartition pour continuer à vivre dans des conditions environnementales qui leur sont favorables. Les auteurs de cette étude ont démontré, par le biais de la modélisation, que les aires de distribution géographique de 8 poissons que l’on pêche et que l’on consomme communément en Méditerranée (dorade, loup, rouget de roche, rouget de vase, merlu, baudroie, sole et pageot), pourraient diminuer d’au moins 20% d’ici 2100 dans le cas d’un réchauffement modéré des températures et d’au moins 53% dans le cas du scénario de réchauffement le plus pessimiste. La fréquence d’observation de ces espèces diminuera considérablement en Mer Méditerranée et augmentera dans les mers du nord de l’Europe. Cette réallocation des stocks à l’échelle de Zone Economiques Exclusives ne sera pas sans répercussion sur les pêcheries nationales des différents pays qui bordent la Méditerranée et ces résultats démontrent l’urgence de mettre en place des mesures de gestions et d’adaptation adéquates face au réchauffement climatique.

Cette étude a été réalisée dans le cadre du projet CLIM-ECO², porté par le laboratoire ECOSEAS, et financé par la Fondation Prince Albert II de Monaco.

Benoit Dérijard, Chercheur CNRS au Laboratoire ECOSEAS (UMR7035 Université Côte d’Azur CNRS) explique, au micro d’une équipe de France 3 Côte d’Azur, les conséquences du réchauffement climatique sur la migration de poissons exotiques en Méditerranée.

Ce scientifique s’inquiète de la prolifération de poissons toxiques et dangereux pour les écosystèmes méditerranéens : les poissons se font manger par des carnivores invasifs et les forêts d’algues se font dévorer par d’autres espèces qui sont herbivores.

Certains poissons exotiques représentent également un réel danger pour l’homme.

Observer la nature pour son plaisir, c’est bien… mais observer et faire profiter la communauté scientifique de ses observations, c’est encore mieux !

Virginie Raybaud, enseignant-chercheur au laboratoire ECOSEAS, a formé les plongeurs de l‘association Nemo Plongée Cannes, à un protocole de sciences participatives mis au point par Patrice Francour, ancien membre du laboratoire : le protocole FAST (Fish Assemblage Sampling Technique). Cette méthode permet le recensement des peuplements de poissons côtiers de façon ludique mais informative pour les scientifiques.

Les plongeurs formés pourront participer à la collecte de données cet été, et ils transmettront leurs observations au laboratoire. Les données recueillies pourront être comparées avec celles des années précédentes pour suivre l’évolution des peuplements de poissons sur nos côtes.

Une nouvelle étude publiée par des chercheurs du laboratoire ECOSEAS montre que la litière de Posidonia oceanica, qui s'accumule sur les petits fonds des plages de la Méditerranée, est importante pour les poissons car elle leur fournit nourriture et refuge. L'étude a trouvé une plus grande richesse spécifique et une densité de poissons plus élevée sur des tâches de litière que sur des fonds sableux. Ces résultats peuvent aussi avoir des implications directes et indirectes pour la gestion de la litière de Posidonia oceanica sur les plages.

 

A new ECOSEAS study published by researchers from the ECOSEAS laboratory shows that patches of Posidonia oceanica litter, which accumulates in the surf zone of Mediterranean beaches, are important for fish species because they provides food and shelter. The study found higher species richness and fish density on litter patches than on sandy bottoms. These results may also have direct and indirect implications for the management of Posidonia oceanica litter on beaches.

Une équipe de télévision France 3 Côte d’Azur a suivi des scientifiques du laboratoire Ecoseas qui étudient les forêts de cystoseires, algues brunes endémiques de la Méditerranée, localement menacées de disparition.

 

Essentielles à la biodiversité marine, la perte de ces forêts transforme les écosystèmes en véritables déserts.

 

Sur les rochers de Saint-Jean-Cap-Ferrat, les chercheurs s’appliquent à réimplanter de jeunes pousses d’algues, cultivées in vitro au laboratoire, dans leur milieu naturel, afin de restaurer les forêts perdues.

Le second volet du sixième rapport d’évaluation du GIEC a été dévoilé ce 28 février. Traitant du thème « impacts, adaptation et vulnérabilité », il indique que l'étendue et l'ampleur des impacts du changement climatique sont plus importants que ceux estimés dans les évaluations précédentes. Il se concentre sur l'adaptation et alerte sur le fait que "s’adapter au changement climatique est possible si le réchauffement est limité à 1,5°C ou 2°C".

A l’occasion de la sortie de ce rapport, le projet CLIM-ECO², porté par le laboratoire ECOSEAS, a été mis en avant par le LIA-ROPSE au travers de la publication d’une vidéo et d’un article. Ce projet pluridisciplinaire a été fait en collaboration avec le Centre Scientifique de Monaco. Il porte sur l’étude de l’impact des changements climatiques sur les pêcheries méditerranéennes, d’un point de vue écologique et économique. Il a été financé par la Fondation Prince Albert II de Monaco.

Impact de la pollution sonore sur les juvéniles de sparidés méditerranéens

Impact of noise pollution on Mediterranean sparid settlers

Eugenio Di Franco

 

L’environnement marin est extrêmement sonore et les animaux marins utilisent ces sons pour plusieurs activités essentielles. Depuis la révolution industrielle, les activités humaines en mer n’ont cessé d’augmenter, ce qui a entrainé la production de sons pénétrant dans le milieu marin et induisant des effets néfastes allant de légers changements comportementaux ou physiologiques jusqu’à des lésions internes ou externes, voire la mort des individus. Cependant, il existe encore de multiples lacunes dans la compréhension de l’impact de la pollution sonore marine (PSM) sur les individus jusqu’aux écosystèmes. /…/ lien vers le résumé détaillé

 

The underwater marine environment is full of sounds which are used by marine animals for many essential activities. Since the industrial revolution, human activities at sea have been ever increasing, inducing the production of sounds underwater having multiple negative impacts of MNP ranging from mild behavioral or physiological changes up to internal or external injuries and even death of the individuals. However, there are still important knowledge gaps to fill to better understand the impacts of MNP from single organisms up to entire ecosystems. /…/ more details

Within the framework of the ANR project: “PAVIS: Assessing the relationships between marine protected areas and invasive species”, Sylvaine Giakoumi (PI of the project) collaborated with the comic artist Noot (http://pencilpixel.be) to produce an e-comic about Marine Protected Areas (MPAs) and invasive fishes. The main objective of PAVIS was to 1) provide evidence on whether the restoration of high-level fish predator populations within Mediterranean MPAs can trigger a top-down control on invasive alien fishes, and 2) identify and prioritize management actions for the control of invasive species. The main findings of PAVIS suggest that MPAs alone are unlikely to control invasive fish populations and thus, additional management measures should be taken within MPAs and unprotected areas, such as the targeted removal of invasive fish for consumption or other uses. Another very important management action, identified by expert scientists who collaborated within the framework of PAVIS, is education and raising public awareness about biological invasions and their impacts on native species and communities. Our comic "PAVIS FISHTALES" contributes towards that direction. Enjoy!

Alexandre Schickele: Climate induced distribution shifts: the case of European small pelagic fishes

Predicting future climate induced shifts on marine species distribution has become an important challenge for sustainable resource and ecosystem management. Our study aims to investigate the potential distribution changes of the most harvested small pelagic fish (SPF) species in the Mediterranean Sea. Species distribution models have been extensively used to over last years to investigate potential future distribution shifts. However, no consistent framework to calibrate and evaluate these models exists. Therefore we developed a comprehensive numerical procedure based on recent scientific advances, allowing a better consideration of sampling biases and improving the modelled distribution. Both temperature mean and variability appear as the major factors driving SPF’s distribution. Regardless of the emission scenario, the models converge toward a decrease in climate suitability in the Mediterranean Sea for SPF, leaving the Adriatic Sea and the Gulf of Lion as the last suitable areas in case of a pessimistic scenario such as RCP8.5.

Eugenio Di Franco: Impact of noise pollution on the development and settlement of coastal fish juveniles

The undersea environment has long been depicted as a silent world. Research carried out in the last decades, however, has raised a growing awareness about sounds and noises as important components of the marine environment. The raise of global industrialization and trading has resulted in a dramatic increase in anthropogenic noises at sea. Coastal areas, in particular, are experiencing an unprecedented increase in human population, urbanisation, industrial and touristic settlements. Most of these activities generate or contribute to the so- called “noise pollution”. There is increasing evidence that anthropogenic noise may impact a large variety of marine animal species. The effects of anthropogenic noise on marine organisms can range from very weak effects to immediate death. The aim of this thesis will be to test whether behavioural, morphological and physiological variables of juvenile sparid fish are affected by different levels of anthropogenic noise, with the objectives of better understand its biological impact on marine organisms to ecosystems.

Elena Desidera: Characterization of the spawning aggregations of the Dusky grouper, Epinephelus marginatus (Lowe, 1834) in the Marine Protected Area of “Tavolara - Punta Cavallo” (Sardinia, NW Mediterranean)

The Dusky grouper, Epinephelus marginatus, is an ecologically and economically valuable fish, highly vulnerable to overfishing due to slow growth rates, late sexual maturity, protogynous hermaphroditism and reproduction via spawning aggregations. Fishing caused dramatic declines in density and size of this fish in many areas of the Mediterranean Sea. Nowadays, this species is abundant only in Marine Protected Areas (MPAs), where its spawning aggregations are mostly documented. This multi-disciplinary project aims at investigating the effect of protection measures on Dusky groupers’ spawning aggregations in the MPA of “Tavolara-Punta Cavallo” (Sardinia). These spawning aggregations are characterized by collecting and analyzing data about i) the historical local ecological knowledge of the species, ii) abundance, iii) reproductive-related behaviours, and iv) courtship-related sound production patterns of Dusky groupers at the study sites. The project will help support monitoring and management programs to protect this endangered species during a vital phase of its life cycle. Link to presentation

Elisabeth Riera: An easy method to assess 3D underwater habitat complexity

It is a common theme in ecology that 3D habitat complexity begets faunal diversity and abundance. However, complexity is a parameter that still remains difficult to assess in the field, especially underwater. Most studies employ qualitative or semi-quantitative measures, which limits comparison between them. Recently, we have developed a method to quantitatively assess the complexity; we computed an index providing a quantitative measure of the abiotic complexity of habitats. First, based on the rugosity and the surface–volume ratios of the structure, which define the structure refolding degree important for the settlement of sessile species. Secondly, based on Shannon diversity computed on the habitat cavities that define shelter for mobile species. Those parameters can be measured directly underwater and can also be computed on a digital model representing the 3D structure of the habitat. First results on fictive 3D models and artificial reefs 3D models give promising perspectives. Link to presentation

Since several years, ECOMERS collaborates with IUCN within several specialist groups. Several contributions to the Red List have been produced (see the complete list in the "Read more" section). In November 2018, the IUCN Red List of Threatened Species published the new global assessments on Groupers. ECOMERS contributed to the status evaluation 6 of these species: the White Grouper (Epinephelus aeneus), the Dogtooth Grouper (E. caninus), the Goldblotch Grouper (E. costae), the Dusky Grouper (E. marginatus), the Haifa Grouper (Hyporthodus haifensis) and the Mottled Grouper (Mycteroperca rubra).

Two species are considered as Data Deficient, E. caninus, E. costae, two as Least Concern, H. haifensis, M. rubra, one as Near Threatened, E. aeneus, and one as Vulnerable, E. marginatus. The previous status of E. marginatus, the most important species within the Mediterranean basin, was Endangered. This change from EN to VU status does not prove that there are some improvements of the status of the dusky grouper. The population trend is clearly decreasing on its whole geographic distribution. However, the change in status from the previous assessment reflects an improved application of the IUCN Red List Categories and Criteria, as well as a better understanding of available data. It means that further research is needed on its population status, especially in the southwestern Indian Ocean, the southwestern Atlantic and West Africa, and actions that reduce fishing effort are greatly needed. Similarly in the Mediterranean, more research efforts have to be deployed to assess the current fishing effort on this species.

It is also important to highlight that these 2018 status evaluations for the Grouper species are global, i.e. considering their whole geographical distribution. At a regional scale, the Mediterranean, the present status of the Dusky Grouper is still Endangered.

CREOCEAN and GEOLAB companies are developing a methodology and know-how in underwater photogrammetry. The objective is to reconstruct in 3D as accurately as possible objects immersed from series of underwater photos. A modelling of the 3D printed artificial reefs immersed in Larvotto Marine Protected Area has been recently conducted in collaboration with AMPN and ECOMERS. The main objective is to compare the theoretical model used for 3D printing with the model reconstructed by photogrammetry. This modelling could be integrated into the work conducted by Elisabeth Riera as part of her doctoral thesis on the evaluation of the tridimensional complexity of all types of artificial reefs. Ultimately, this technique can also be applied in other areas of research.

Monitoring of marine benthos with an hyperspectral camera: a first in the Mediterranean

Habitat destruction is one of the main causes of the decline of marine biodiversity and fisheries resources. An artificial reef can be considered as a tool to protect or restore these habitats and their declining biodiversity. The Barcelona Convention defines artificial reefs as "structures specifically built to protect, regenerate, concentrate and / or increase the production of biological marine resources, whether for fishing or nature conservation, which includes the protection and protection of the environment. regeneration of habitats ". In response to these problems, nearly 88,000 m3 of artificial reefs, mostly made of concrete, have been deployed on the Mediterranean coast of France for some thirty years. To date, the assessment of reef performance has focussed primarily on fish communities and has almost completely ignored the development of epibiosis (biofilm and macrofouling). Historically in the Mediterranean, the first published works in the 70s deal with the species of macrofouling. Thereafter, during the last decades, most of the works focussed on the fish assemblages. However, the biofilm (mainly bacteria and unicellular micro-algae) and macrofouling (mostly algae and fixed invertebrates) are the first elements of the food web that will allow the installation and development of the fauna of large invertebrates (crustaceans) and fish on or around artificial reefs.

In November 2017, 6 large 3D printed artificial reefs were immersed in the Larvotto marine protected area (Monaco). ECOMERS and BOREA (Museum of Natural History of Paris), in collaboration with AMPN, launched a long-term monitoring of these reefs, including an analysis of biofilm and macrofouling.

To answer this, an innovative technique is being tested with the use of an immersible hyperspectral camera. This camera is developed by PlanBlue, a start-up from the Max Planck Institute (Germany). Briefly, hyperspectral imaging is a technique combining imaging and spectroscopy where each image is taken for a narrow band of the electromagnetic spectrum. For example, the human eye sees light in three bands (red, green, and blue) while hyperspectral imaging can 'see' in a very large number of bands typically ranging from visible to near infrared. Each species has a particular signature (hyperspectral image) that can be used to identify it. The development of a submergible camera allows to acquire underwater scuba images of different substrates colonized and thus to quickly have a precise identification (species or genus) of the species present. This speed and ease of identification are the main highlights of this camera. Once the validation is done (association between a light spectrum and a species or group of species), it will then be easy to determine the composition of the macrofouling species. Moreover, this promising technology go further than the simple identification of species. This camera can also give information about the physiological activities of photosynthetic species growing over the time.

This innovative technique has never been used in the Mediterranean. Its development in Monaco by ECOMERS and AMPN in partnership with CREOCEAN and its validation as a method of monitoring the macrofouling will be a first. This technique could subsequently be used in the monitoring of the benthos, whether on artificial or natural substrate. The prospects of application far exceed the only artificial reefs.

Oceanographic Museum of Monaco, June 20, 2018


A conference organized by the Association Monégasque pour la Protection de la Nature (special thanks to Jacqueline Gautier-Debernardi and Jean-Marc Ferrie, AMPN, and to Robert Calcagno and his staff, Oceanographic Museum of Monaco) has be led by Patrice Francour (ECOMERS laboratory and former president of the Scientific Committee Prado Artificial Reefs, Marseille). It focussed on the first Monegasque artificial reefs to the latest reefs, printed in 3D, immersed in November 2017.

Monatage pour site Web ECOMERS réduit

The first artificial reefs date back to the 17th century and were submerged in Japan, the undisputed leader in this field. Today, throughout the world, they serve to preserve, restore and improve the coastal ecosystems and related ecological services. Described simply as submerged structures, positioned deliberately on the seabed, they aim to imitate certain characteristics of natural rocky habitats. In the Mediterranean the use of artificial reefs began during the 20th century but only increased in quantity after 2000. In Monaco the first artificial reefs used were those associated with the creation of the Larvotto marine reserve some 40 years ago. In France and Monaco artificial reefs principally provide the means to sustain artisanal fisheries or to restore damaged habitats. Generally speaking they have simple shapes, nothing complex architecturally and for the most part are made of concrete.

The recent increase in the use of artificial reefs has essentially been motivated by the extent of damage to the coastline and the need to find solutions to remedy the problem. But how can an ancient concept of artificial reefs made of concrete evolve to face such a challenge ?

Recent progress in technology has led to the idea of more complex designs of artificial reefs thanks to the use of 3D printing. Using natural materials, mainly sand from the Dolomite, has allowed the creation of ecological reefs. Thanks to the joint efforts of the Monegasque Association for the Protection of Nature, the Boskalis company and the Prince Albert II of Monaco Foundation, six 3D printed reefs were immersed in November 2017 in the Larvotto MPA: a first in the Mediterranean and in the world due to the size of the reefs. The research undertaken by international scientific teams (ECOMERS, BOREA, Boskalis, D-Shape) prior to this project in Monaco was original, innovating and advanced our knowledge in the field of artificial reefs, as much in terms of management (how to put in place a programme for submerging artificial reefs) as in scientific terms (which designs, what materials).

The full presentation can be dowloaded here in French.After the presentation, Elisabeth Riera, (PhD student in ECOMERS lab; her PhD subject deals with the 3D printed artificial reefs immersed in Monaco) and Enrico Dini have joined Patrice Francour to answer the questions of the audience. Enrico Dini, CEO of D-Shape (https://d-shape.com/) is the "father" of the giant 3D printer which printed the 3D ARs. He was also involved in the world first project of 3D printed ARs immersed in Bahrain in 2012.

Landscape ecology is a multidisciplinary field that combines the spatial approach of geography with functional ecology. Concerning marine environment, a submerged landscape, called seascape, is defined as a spatially heterogeneous area of coastal environment. Measurement of spatial patterns plays a central role in monitoring environmental change and for studying the multi-scale processes that drive organism distributions and biodiversity.

In 2011, ECOMERS co-organized with the French Agency for the Marine Protected Areas an international workshop on the seascape. The contributions have been published in a Springer volume (Underwater seascapes - From geographical to ecological Perspectives. 2014. Musard O., Le Dû-Blayo L., Francour P., Beurier J.P., Feunteun E., Talassinos L. (eds). Springer Science & Business Media). In collaboration with CREOCEAN company, ECOMERS published in this book a method to assess the seascape integrity (Thorin S., Bodilis P., Schvartz T., Durtieux E., Francour P. 2014. Seascape integrity assessment: a proposed index for the Mediterranean coast: 263-275). The aim of this paper was to propose a relevant seascape index focussing on Mediterranean littoral areas, moreover rocky habitat that constitutes one of the most important and characteristic habitats of the north-western Mediterranean coastal areas. The methodology proposed to score marine sites addresses three factors: biological, geomorphologic (i.e. 3D complexity) and anthropogenic. The goal was to build a functional and relevant tool that could eventually be used for a large scale geographical analysis of submarine landscapes along the north-western Mediterranean coast. The proposed index can qualitatively assess the value of the seascape within a site. Statistical tests showed that the proposed index is an accurate and relevant proxy of the seascape complexity value. The seascape integrity index we developed can then be a new tool that could complement other existing biological indices.Paysage

Recently, in collaboration with NaturDive, an association of non professional Scuba divers interested in marine ecology, Patrice Francour (ECOMERS) proposed a training, including lecture and scuba diving, to involve non professional divers in seascape monitoring along the Riviera coast. The aim of this citizen science initiative is (1) to gather data on seascape integrity of most of the diving spots along the coast, (2) to provide some managers (marine protected areas, Natura 2000 areas, etc.) with quantitative data, scientifically validated, and (3) to improve Scuba divers awareness on the ecological importance of seascape.

This seascape initiative is included in the ECOCIMED, a program of citizen science, managed by ECOMERS and AMPN (Association Monégasque pour la Protection de la Nature; manager of the MPAs in Monaco). Contributions to ECOCIMED are available of the ECOCIMED Facebook page.

Title: Climate induced changes in Mediterranean fish communities:
A modelling approach
Abstract: Last decades, climate driven changes, including sea surface temperature increase in the Mediterranean Sea, have modified the native species’ abiotic environment, inducing northwards shifts in their distribution areas. During the same time, warm-water lessepsian migrants have settled along the south-eastern Mediterranean coast leading to competition with endemic species. The current distribution of several species including most invasive, most harvested and keystone species will be assessed using Ecological Niche Models (ENM). These models are calibrated with a given species spatial occurrence data and the associated environmental variables. Coupled with several global ocean circulation models and IPCC scenarios, we will be able to predict Mediterranean species distribution under climate change for the next decades. Using results of ENMs as input, trophic models will be calibrated on specific areas of the Mediterranean Sea to assess the complexity of climate induced changes on several type of ecosystem, including MPAs and cold-water ecoregions.

Title: Evaluating the effects of protection measures
on the reproductive biology of the Dusky Grouper, Epinephelus marginatus
Abstract: The Dusky grouper, Epinephelus marginatus, is an ecologically and economically valuable fish, highly vulnerable to overfishing due to slow growth rates, late sexual maturity, protogynous hermaphroditism and reproduction via spawning aggregations. Fishing caused dramatic declines in density and size of this fish in many areas of the Mediterranean Sea. Nowadays, this species is abundant only in Marine Protected Areas (MPAs), where its spawning aggregations are mostly documented. This multi-disciplinary project aims at evaluating the effect of reserve protection on Dusky groupers’ spawning aggregations in Tavolara–Punta Coda Cavallo MPA (Sardinia, Italy), by collecting data about i) historical local fishery and knowledge of the species, ii) Dusky grouper populations demography and iii) reproductive activity, and iv) spawning-related sound production patterns (to listen sounds produced by groupers, click here).The project will have major management and socio-economic implications for supporting MPAs effectiveness in protecting this valuable endangered species during a vulnerable phase of its life cycle.

Title: Optimization of a new generation of artificial reef:
a pilot study in Mediterranean Sea.
Abstract: Artificial reefs (ARs) have been defined as "submerged structures placed on the seabed deliberately, to mimic some of the characteristics of natural reefs”. Most of the artificial reef immersed in the Mediterranean Sea are made with concrete that presents potential pollution and shows a poor complexity compared to natural rocky habitats. Our study aims to optimize a new generation artificial reefs designed by 3D print, both for their structural potential and for the ecological suitability of the materials used to design them. To assess the quality of any kind of substrate used for ARs, we monitor the first stage of colonization (biofilm and macrofouling), a key element in the colonization of ARs and the development of its trophic network. Secondly, to assess the structure of ARs, a quantitative complexity index of marine habitats is in development. This will allow testing a potential correlation between these indexes and the diversity and abundance of species associated with complexity of habitats. This will help in the future to choose the best design to attract species of interest. Link to presentation

Title : Impact of Fishing on the Ichthyofauna in the North Lebanese coast
Abstract: An important number of Lessepsian fishes colonize the Lebanese coast, and become a part of the local fish market. Fishing in Lebanon is not subject to the application of laws, or regulations, which are applied to the minimum. The Lebanese coast is considered to be overfishing. The study is made in north Lebanon and focus on fishing techniques, fishing vessels, target species and distribution of fisheries. Results of species caught will be divided into: primary target, secondary target, accessory target, bait target, and new primary target. Then a classification of fishing techniques is presented based on their impact on fishes listed on IUCN Red List of Threatened Species. Finally, the quantity of captured species will be collected for each fishing technique. Several methods are used to collect the data: direct Interviews with fishermen, survey, accompany fishermen in different fishing techniques, and weekly data collection from 117 fishermen representing a percentage of fishing techniques and representative fishermen number in north Lebanon.

Six artificial reefs printed with a giant 3D-printer using natural products (sand of Dolomite and volcanic ash) have been immersed on November 02 in the Larvotto marine protected area in Monaco. This is a first in the Mediterranean and worldwide by the size of printed reefs ( 2,500 kilos each). This innovative project is supported by the Boskalis Company and the ECOMERS laboratory with the support of the Prince Albert II of Monaco Foundation and in partnership with the Association Monégasque pour la Protection de la Nature (Manager of Marine Protected Areas of Monaco).

Slide 1 3D
The use of a 3D printer allow to mimic the complexity of the natural environment and can therefore facilitate the restoration of ecosystems by creating suitable habitats for fish and macroinvertebrates.
Significant studies have been carried out by Boskalis to design a material that meets several requirements: water resistance, strength, compatibility with 3D printing technology and above all a lack of harmful effect on the environment.
In parallel, research programs were launched in our laboratory by Patrice Francour and Elisabeth Riera to select the most favourable substrates for subsequent colonization by fauna and flora or to develop a method for accurately measuring the structural complexity of artificial reefs.
Long-term monitoring of the reefs immersed in the Larvotto Marine Protected Area will be rapidly implemented (ECOMERS and AMPN) to follow the colonization of the reefs. In the heart of the Larvotto Marine Protected Area, a natural laboratory for scientists, this program will also promote the development of innovative methods of monitoring. The experience gained can thus be put at the service of marine protected area managers who would like to optimize the restoration of degraded land by human activities.

Taking advantage of the sampling campaign in Croatia, conducted within the project FishMPABlue 2, Ecomers researchers participated to a meeting with local small scale fishermen. The more appropriate governance tools to enhance management of small scale fisheries in the MPAs have been discussed together. In collaboration with international experts (Nathan Bennett, David Gill, Federico Niccolini), Ecomers developed a questionnaire in order to investigate the human dimension of small scale fisheries in the 11 Mediterranean MPAs included in the project.
