Aires marines protégées et récifs artificiels : méthodes d'évaluation, protocoles expérimentaux et indicateurs ArchiMer
Claudet, Joachim.
Marine Protected Areas' (MPAs) and Artificial Reef's (ARs) management requires complex assessment and monitoring programmes, dealing with different sources of variability. We studied and developed experimental designs and analysis methods suited for the establishment of a monitoring of MPAs and ARs. This methodology is developed from existing data sets in the Northwestern Mediterranean. We build multi-criteria indicators allowing a statistically testable diagnosis of the impact of MPAs and ARs on reef fish assemblages. Using ecological performance indicators permits to monitor and to give an image of the assessed system to managers. It was possible to show the global response of the fish assemblages to the protection by a MPA. This response was evidenced...

Appui à la mise en oeuvre de la Directive Cadre Stratégie pour le Milieu Marin - DCSMM ArchiMer
Fabri, Marie-claire; Andral, Bruno.
La Directive Cadre Stratégie pour le Milieu Marin (DCSMM) promeut une approche écosystémique de la gestion des mers et des océans. Face à cet objectif ambitieux et dans le cadre de leur convention signée en 2005, l’Agence de l’Eau Rhône Méditerranée et Corse a demandé à l’Ifremer une analyse de l’application de la DCSMM dans la sous-région Méditerranée occidentale, et de son articulation, notamment avec la Convention de Barcelone et la Directive Cadre sur l'Eau (DCE). Ce soutien vient en complément de celui apporté par l’Ifremer au plan national au Ministère de l’Ecologie, de l’Energie, du Développement Durable des Transports et du Logement dans le périmètre de son expertise auprès de l’Agence de l’Eau. Une analyse des onze descripteurs recommandée par la...

Des modèles et des indicateurs pour évaluer la performance des Aires Marines Protégées pour la gestion des zones côtières. Application à la Réserve Naturelle des Bouches de Bonifacio ArchiMer
Rocklin, Delphine.
These last decades have been characterized by a great development of fishing techniques, contributing to the overexploitation of numerous marine fish stocks. In order to limit this collapse and to restore impacted communities, the implementation of management measures was necessary. Marine Protected Areas (MPAs), initially developed to protect remarkable habitats and associated biodiversity, are more and more used as a tool for spatial management of fishing activities, by adult export and/or larvae migrations from protected zones to surrounding fisheries. The aim of this PhD was to use indicators and predictive models for evaluating the impact of the Bonifacio Strait Natural Reserve (Corsica) implementation on fish communities and the benefits of such...

Document technique de la campagne Nourveys. Programme de surveillance DCSMM ArchiMer
Baudrier, Jerome; Schlaich, Ivan.
Parmi les recommandations du programme de surveillance de la DCSMM, le suivi des poissons et céphalopodes démersaux des milieux meubles côtiers a été jugé prioritaire. Un suivi pérenne et opérationnel doit ainsi être mis en place au cours du premier cycle (2014-2020), il est basé sur une série de campagnes récurrentes à déployer dans les fonds inférieurs à 40 mètres, en complément de celles déjà existantes sur les façades Manche et Atlantique (Nurse, Nourseine, Noursom). Les suivis sont opérés dans les zones de nourriceries côtières des poissons bentho-démersaux, constituant des habitats essentiels pour de nombreuses espèces marines. La caractérisation de l’état écologique des peuplements et l’étude de la fonctionnalité des habitats de nourriceries...

Etude bibliographique sur l’impact des feux sur la chimie de l’environnement. Projet SEARSÉ ArchiMer
Mai, Tepoerau.
Forest fire is an important issue in New Caledonia. During the dry season, forest fire can remove vegetation from large areas (from 10 000 to 30 000 ha per year on average), leaving metal-rich soils uncover and more exposed to runoff. The impact of forest fires on the chemical and microbiological quality of water has been poorly studied in New Caledonia, either for river water bodies or coastal lagoon water bodies. The purpose of this document is to review the current knowledge on forest fires impacts on water quality that has been documented in the worldwide literature, a topic of increasing importance in the context of global warming.

Etudes des activites de peche dans le golfe du Morbihan, peche professionnelle ArchiMer
Peronnet, Isabelle; Talidec, Catherine; Daures, Fabienne.
The objective of the study is to improve knowledge of coastal fishing activity in the halieutic and economic spheres. It consists of three sections: On-board professional fishing, professional shellfish gathering, and leisure fishing, this last one being the subject of an independent report (Lesueur and Drouot). The methodology applied is based on implementation of specific surveys about the ships that frequented the Gulf of Morbihan in 2001. The emphasis was placed on identifying the occupations practiced in this zone, on describing these activities and their intensity as well as on analysing the economic performance of these fleets. The management methods, regulation of shellfish gathering on listed sites as well as their impacts on the environment are...

Évaluation du descripteur 5 « Eutrophisation » en France métropolitaine. Rapport scientifique pour l’évaluation 2018 au titre de la DCSMM ArchiMer
Devreker, David; Lefebvre, Alain.
This report is the second assessment of French marine water eutrophication status (descriptor 5) done in the framework of the MSFD. The goal of this report is to determine if French marine water reach the Good Ecological State as defined by the MSFD. It stands next to the initial evaluation made in 2012, from which it is an update. It introduces the second cycle of the Marine Environment Action Program. It shows that French marine waters, behind the 12 nm line, reach the GES as defined by the MSFD. Problems link to eutrophication occurs in marine waters above the 12 nm, where 6.5% of the area do not reach the GES.

The ecosystems exploited by fishing are complex. The species which are sought after and their distribution rely on numerous processes, in time and space. The understanding of marine ecosystems requires important means and diverse information including those of professional fishing and scientific cruises. At first, scientific fishing cruises aimed to explore marine fauna and discover new halieutic resources. They were in line with the exploration cruises carried out by Prince Albert 1st of Monaco at the end of the XIXth century. However, since the beginning of the 1970s, they have been focusing on the quantification of the resources exploited by fishing. [...] After a series of "Understanding keys" aimed at helping the reader understand the methodology and...

Impact des mesures de gestion sur la dynamique de la pêcherie pélagique du golfe de Gascogne : Quelles certitudes ? Quels descripteurs ? ArchiMer
Lehuta, Sigrid.
Quantitative evaluations of management measure impact on resource and fleet viability are required to provide diagnostics and feed decision process. Fisheries are complex systems where numerous dynamics interact at various spatial and temporal scales. This complexity and the difficulty to observe marine systems are responsible for the high uncertainty surrounding fishery functioning that makes it hard to identify adequate management measures. The increasing consideration of uncertainties in diagnostics argues in favor of robust management measures rather than optimal management measures. Identifying robust management measures requires the development of models that account for complexity and uncertainty in the description and prediction of management...

L'état des communautés exploitées au large des côtes de France. Application d'indicateurs à l'évaluation de l'impact de la pêche. Bilan 2004 – Edition 2009 ArchiMer
Morin, Jocelyne; Bertrand, Jacques; Cochard, Marie-laure; Coppin, Franck; Leaute, Jean-pierre; Lobry, Jeremy; Mahe, Jean-claude; Poulard, Jean-charles; Rochet, Marie-joelle; Schlaich, Ivan; Souplet, Arnauld; Trenkel, Verena; Vaz, Sandrine; Verin, Yves.
Since about twenty years, Ifremer have carried out fishery surveys along the French coasts. A dynamic indicator-based approach to the assessment of multi-stock fisheries has been applied to these data series. Reference points for non-commercial populations and community indicators are seldom available, but reference directions are well established: it is known whether fishing will increase or decrease the indicator, hence the direction that should be avoided. A set of simple indicators of fishing impacts on fish populations and communities were estimated from time-series data provided by scientific surveys (population abundance and average length, community total biomass and number, average length and weight, and size spectrum). Trends in these indicators...

Rapport de campagne vidéo «STAVIRO» - Parc Naturel Marin de Mayotte du 6 au 24 novembre 2017. ArchiMer
Giannasi, Paul; Gaboriau, Matthias.
La campagne STAVIRO Mayotte 2017 avait pour objectif d’acquérir les données afin de dresser un état des lieux des peuplements ichtyologiques d’intérêt commercial sur l’ensemble des récifs de Mayotte à l’aide du protocole STAVIRO. Elle a permis de confirmer la faisabilité du déploiement du protocole STAVIRO sur les récifs de Mayotte, et de valider le dimensionnement d’une campagne couvrant l’ensemble du complexe récifolagonnaire de Mayotte et du banc de l’Iris. Au total, 276 stations ont été posées pour 203 stations considérées comme exploitables (bonnes ou moyennes). L’implication de nouveaux partenaires et prestataires dans cette campagne (RNN M’Bouzi, opérateurs touristiques) permet de faire connaître et de familiariser les acteurs avec les techniques...

Suivi et évaluation de la pêche professionnelle au sein d'une Aire Marine Protégée : protocoles d'enquêtes et indicateurs de pression et d'impact. Application au Parc Marin de la Côte Bleue ArchiMer
Leleu, Kevin.
La surexploitation des ressources halieutiques a conduit à une crise majeure du secteur de la pêche professionnelle. Dans ce contexte, les pêcheries artisanales, et notamment les pêcheries aux petits métiers côtiers, apparaissent comme des modes d’exploitation potentiellement durables des ressources côtières. La diversité des engins utilisés et des espèces ciblées rend néanmoins complexe le suivi de cette composante importante de la pêche professionnelle. L’activité de pêche artisanale reste ainsi très peu évaluée en Méditerranée, et notamment à l’échelle d’une Aire Marine Protégée (AMP). Les AMP sont pourtant de plus en plus utilisées comme des outils de gestion de ces pêcheries, les effets des différentes mesures de gestion mises en place étant à même de...
