Etude de la contamination de la langouste blanche Panulirus argus et de la langouste brésilienne P. guttatus par la chlordécone le long de la côte atlantique de la Martinique. Campagnes 2011
Provedor de dados: 5
Autores: Bertrand, Jacques; Dromer, Clement; Reynal, Lionel.
Spiny lobsters are an important component of the coastal fisheries around the Martinique island. This study aimed to assess the contamination by kepone of the two main species Panulirus argus and P. guttatus in the main fishery area laying along the eastern coast of Martinique. The objectives of the study were to describe the distribution of the spiny lobster contamination in the area, to explore possible relationships with some biological parameters such as individual size, sex and colour of tegument, as well as characterize difference of kepone concentration between the muscle and soft flesh of the head, in view of helping the definition of further fishery management measures. The analyses were done from chemical analyses of 125 samples of spiny lobsters...

Une expérience de réflexion commune recherche - profession sur l'organisation de la gestion des pêches en Méditerranée
Provedor de dados: 5
Autores: Bertrand, Jacques; Catanzano, Joseph; Rey, Hélène; Tempier, Elisabeth.
The beginning of the 1990s was marked by the will of French and European Community policy makers to change the methods of managing fishing in the Mediterranean. To contribute to this dynamic by an analysis on fishing operations based on exploitation itself and by developing proposals to reinforce participation of fishing professionals in the management of regional fishing were the objectives of the study presented below. The research was conducted based on principles of action research, involving a common discussion among the actors. Within a context of implementing the principle of subsidiarity and Community integration, it became necessary to anticipate the methods of reinforcing the capacity of professional facilities so that the latter could continue...

Assessment of impacts from human activities on ecosystem components in the Bay of Biscay in the early 1990s
Provedor de dados: 5
Autores: Lorance, Pascal; Bertrand, Jacques; Brind'Amour, Anik; Rochet, Marie-joelle; Trenkel, Verena.
The ecosystem-based approach to fisheries management and, more specifically, the European Marine Strategy Framework Directive require the assessment of the state and dynamics of an ecosystem in order to determine suitable management strategies. This paper takes an analytical approach to assess the state of the Bay of Biscay ecosystem in the early 1990s, chosen as a period of reference because key monitoring data series have been collected since then. To assess the state of the ecosystem, the pressures exerted by six broad categories of human activities were examined. A literature review of the ecosystem components was made and a component tree was tailored according to data availability. Data rich components were subdivided into subcomponents for their...

We present a method for combining individual indicator results into a comprehensive diagnostic of fishing impacts on fish populations and communities. A conceptual framework for interpreting combined trends in a set of simple indicators is proposed, relying beforehand on qualitative expectations anchored in ecological theory. The initial state of the community is first assessed using published information. Which combinations of trends are acceptable or undesirable is decided, depending on the initial status. The indicators are then calculated from a time-series and their time trends are estimated as the slopes of linear models. Finally, the test results are combined within the predefined framework, providing a diagnostic on the dynamics of fishing impacts...

The results of a survey on fishers' perceptions of recent changes in the eastern English Channel ecosystem carried out in 2006 were compared with fishery and bottom-trawl survey data. A hypothesis-testing framework was used, testing the null hypothesis that fishers' statements were true, which permitted evaluation of both agreement and disagreement. Overall good agreement between fishers' statements and scientific data was found, and both sources suggested that the fish community in the Channel is undergoing large changes, among which are decreases in some commercially important species; in addition, a number of human pressures impact the ecosystem. Fishers had an accurate perception of changes and their time-frames, but not necessarily of their causes....

Large-scale studies focused on the diversity of continental slope ecosystems are still rare, usually restricted to a limited number of diversity indices and mainly based on the empirical comparison of heterogeneous local data sets. In contrast, we investigate large-scale fish diversity on the basis of multiple diversity indices and using 1454 standardized trawl hauls collected throughout the upper and middle slope of the whole northern Mediterranean Sea (36 degrees 3' - 45 degrees 7' N; 5 degrees 3'W - 28 degrees E). We have analyzed (1) the empirical relationships between a set of 11 diversity indices in order to assess their degree of complementarity/redundancy and (2) the consistency of spatial patterns exhibited by each of the complementary groups of...

Chlordecone in the marine environment around the French West Indies: from measurement to pollution management decisions
Provedor de dados: 5
Autores: Bertrand, Jacques; Bodiguel, Xavier; Abarnou, Alain; Reynal, Lionel; Bocquene, Gilles.
Chlordecone is a very persistent insecticide used in banana plantations of the French West Indies between 1972 and 1993. Chlordecone residues were found in inland water, in agricultural and freshwater products, and in marine organisms. This pollution has become of great concern in 2007. Therefore, a governmental action Plan was launched to better assess the pollution and to improve the consumer’s protection. Within this plan, 1048 samples from 69 different species of marine fishes and crustaceans were collected all around both the Guadeloupe and the Martinique Islands and analyzed. The results confirm the presence of chlordecone in marine organisms, with highly variable concentrations (from the detection limit to 1000 μg.kg-1). In 17.9 % of the samples,...

Autores: Gaertner, J; Bertrand, Jacques; Relini, G; Papaconstantinou, C; Mazouni, N; De Sola, L; Durbec, J; Jukic Peladic, S; Souplet, Arnauld.
The species richness pattern of groundfish species in the entire northern Mediterranean Sea was examined at 3 spatial scales: region, large biogeographical zone and basin. We analysed 1914 trawl hauls collected using a single sampling design in the trawlable areas of the continental shelves between the Strait of Gibraltar and the Strait of Dardanelles (from 36.3 to 45.7 degrees N and 5.3 degrees W to 28 E). Spatial pattern in species diversity was assessed using complementary methods (Chao2 estimates of total species richness, mean species richness and beta diversity). No matter which scale was used, the expected longitudinally decreasing trend in species richness, which has been widely described in previous studies, did not appear when comparing estimates...

The multi-component structuration of the species diversity of groundfish assemblages of the east coast of Corsica (Mediterranean Sea): Variation according to the bathymetric strata
Provedor de dados: 5
Autores: Merigot, B; Bertrand, Jacques; Gaertner, J; Durbec, J; Mazouni, N; Mante, C.
The multi-component aspect of species diversity of groundfish assemblages was examined on the basis of a set of experimental trawl surveys conducted on the east coast of Corsica. We analysed and compared the structuration of diversity within three different bathymetric strata: the continental shelf (60-120 m depth), the upper slope (250-400 m) and the lower slope (450-570 m). For each of these three bathymetric strata, we simultaneously analysed 12 indices that are theoretically complementary and relate to 4 diversity components: (1) the number of species, (2) rarity, (3) evenness and (4) taxonomic diversity. Principal component analysis based on Spearman's correlation coefficients was carried out to investigate empirical relationships between the selected...

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.

Devenir de la chlordécone dans les réseaux trophiques des espèces marines consommées aux Antilles (CHLORETRO)
Provedor de dados: 5
Autores: Bodiguel, Xavier; Bertrand, Jacques; Fremery, Juliette.
La chlordécone est un insecticide organochloré qui a été utilisé aux Antilles de 1972 à 1993 afin de combattre un charançon s’attaquant aux racines des bananiers. Très persistant dans le milieu, la molécule est véhiculée des terres contaminées vers les systèmes aquatiques par le biais des matières particulaires fines, contaminant ainsi le milieu marin côtier. L’objectif de l'étude était de caractériser le devenir de la chlordécone dans les réseaux trophiques de la macrofaune côtière. Il s'agissait en particulier de tenter d’identifier ses voies d’entrée à partir des apports terrigènes et sa propagation au sein de ces réseaux. Le modèle d'étude est une baie de la Martinique, avec les herbiers à phanérogamme comme système de production primaire.  Les...

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).

In the French West Indies islands, the transfer of chlordecone (kepone) from treated grounds towards the marine environment has been proved since the beginning of 2000s. In 2008, a maximal residue limit (MRL) was set at 20 µg / kg wet weight in fish and seafood, and therefore intensified the concern about the risks of high human exposure to the pesticide due to the consumption of contaminated marine products. To answer this concern, several sampling cruises were carried by public authorities and by Ifremer in order to analyze the contamination of the fish fauna around the Guadeloupe island. The data collected within these surveys improved our knowledge on the characteristics of the contamination of fish fauna and allowed to assess the distribution of this...

Large spatial scale variation of demersal fish assemblage structure on the continental shelf of the NW Mediterranean Sea
Provedor de dados: 5
Autores: Gaertner, J; Bertrand, Jacques; De Sola, L; Durbec, J; Ferrandis, E; Souplet, Arnauld.
The spatial structure of demersal fish assemblages on the continental shelf of the NW Mediterranean Sea was examined on a large scale between the Straits of Gibraltar and the Gulf of Lions. In contrast to its predominant role in the spatial distribution of species composition, described worldwide, it seems depth has only a limited effect on the distribution patterns of the total abundance and diversity of demersal fishes. In addition, evidence is provided for the division of the whole study area into 3 geographical fish assemblages. The influence of Atlantic inputs and the semi-permanent Almena-Oran hydrographic front play a key role in defining the Alboran Sea as a specific fish fauna area. Moreover, the clear differentiation between 2 distinct...

An assessment of the state of the fisheries of hake, red mullet and Norway lobster was carried out by using trawl survey data from the MEDITS research programme. The assessment was performed by means of the application of a composite model utilising the total mortality rate Z as a direct index of fishing effort. The studied area covered the whole western Italian coast (Ligurian and Tyrrhenian seas) and the eastern coasts of Corsica. The area was divided into twelve sub-areas, considered to be of similar ecological characteristics with similar initial productivity but considered to experience different rates of exploitation. Available information on fishing fleets and their geographic distribution was used in creating sub-areas. For each one of these...

Recent theoretical and field studies conducted in both terrestrial and marine ecosystems have suggested that diversity could be a more complex and multi-component concept than previously thought. However, it is still poorly understood to what extent the information provided by the various indices is complementary with regard to diversity, and to what extent this complementarity is reproducible in different situations or at different scales of observation. In the present work, we have analysed the reproducibility of the empirical relationships between 11 diversity indices related to four major aspects (components) of species diversity (species richness, rarity, evenness and species taxonomy) in order to determine whether there is a general pattern of...

Campagne internationale de chalutage démersal en Méditerranée (MEDITS). Rapport final
Provedor de dados: 5
Autores: Bertrand, Jacques.
Le présent projet de programme international s'inscrit dans la ligne des recommandations de différents forums scientifiques (CSTP, séminaire européen d'Ancone, etc.) qui ont exprime le besoin de connaissances biologiques sur les espèces démersales exploitées par les flottilles de pêche en Méditerranée. Ces groupes avaient reconnu que les caractéristiques de la pêche dans cette région, et en particulier la forte dispersion de lactivité, ne permettaient pas de recueillir les informations nécessaires à une évaluation globale des ressources halieutiques de la région avec un niveau de précision suffisant à partir des résultats de lactivité des flottilles professionnelles. Le présent projet fait également référence a l'urgente nécessité, reconnue par la...

The integration of fishing management into the ecosystemic approach has been recommended for many years by international consultative bodies; it is also written into international conventions and agreements. The implementation of the ecosystemic approach involves the development of programmes for monitoring exploited ecosystems in order to measure the effects of management steps. Plotting the results of these observations for operational reasons requires formalizing summary performance indicators.  IFREMER has carried out halieutic observation campaigns for some twenty years along the coasts of France from oceanographic ships and chartered ships. The objective of these campaigns is to produce abundance indices of species that are of halieutic interest....

Stability of spatial structures of demersal assemblages: a multitable approach
Provedor de dados: 5
Autores: Gaertner, Jean-claude; Chessel, Daniel; Bertrand, Jacques.
The present work is based on a set of bottom trawl surveys performed in the Gulf of Lions between 1983 and 1992. A new method which couples the STATIS multitable approach with the logic of correspondence analysis (CoA) is proposed to study the stability of spatial organization of demersal assemblages in terms of species composition. This CoA version of STATIS has provided a clear representation of the stable part of the spatial structure of the assemblages. In addition, it gave an insight into the interannual variations of the distribution of each population around the reference structure. Our results showed that the demersal assemblages of the Gulf of Lions exhibited strong spatial structuring, mainly orientated along a bathymetric gradient. This gradient...

The follow-up of the activity of the boats practising offshore fishing in the North-West of the La Réunion Cbaies of the Possession and Paul Saint) was carried out over one year(April 86 - March 87) thanks to the application of a strategy of sampling allowing the collection of the following statistics: total effort and by machine, captures total and by species.The study allowed a first approach of the space-time distribution of the activity of the fleet. It reveals the very high participation of the yachtmen in the halieutic exploitation of the studied sector. It also highlights the importance of tunas in the captures, which in weight are largely majority.

Variabilité spatiale et temporelle d'une pêcherie au filet dans le golfe du Lion. Essai d'évaluation de l'impact d'un récif artificiel
Provedor de dados: 5
Autores: Duclerc, Jean; Bertrand, Jacques.
The laying out of an offshore site in the gulf of Lion has been realized by immersion of concrete structures in 1985. Two complementary studies have been conducted in order to estimate the impact of such artificiel reef. Gillnet fishery surveys have been done in the vicinity of the structures and also on a control site. Moreover the local profcssional fishery has been investigated for two periods of 16 months, one berore and one arter the reef immersion. The results of the gillnet surveys have already been submitted to publication and the present study displays the investigations concerning the local fishery. It has been shown by the gillnet fishing surveys that the artificial reef led in their very close vicinity to variations in marine species...

Do population and community metrics tell the same story about recent changes in Northern Mediterranean fish communities?
Provedor de dados: 5
Autores: Rochet, Marie-joelle; Trenkel, Verena; Gil De Sola, Luis; Politou, Chrissi-yianna; Tserpes, George; Bertrand, Jacques.
This document presents a comparative study of human impacts on the length-structure of fish communities across North-Mediterranean ecosystems. We use survey data to examine trends in length-based metrics and their consistency within and among the two levels of organisation populations and communities, and to suggest interpretations of observed trend combinations. We start from a set of population processes potentially affected by human pressures: fishing will induce mortality especially in target species, whereas the hydrological environment and eutrophication potentially affect recruitment and individual growth. How population changes will be reflected at the community level is expected to depend on community evenness. Based on this expectation, a...

Autores: Bertrand, Jacques; Abarnou, Alain; Bocquene, Gilles; Chiffoleau, Jean-francois; Reynal, Lionel.
During the years 1972-1993, kepone a persistent pesticide has been used in the banana fields of the French West Indies (Martinique and Guadeloupe) to content a weevil. A slow desorption of the molecule from soil induces its transfer to the sea through the rivers from leaching and erosion. This study intended to take stock on the contamination by kepone of the fishery species around the islands fifteen years after the kepone ban. Furthermore other chemical pollutants were sought in fish and shellfish around the Martinique island.   The results confirmed persistence of marine fauna contamination by kepone, mainly in the alluvium areas in front of polluted rivers. They shown also that this contamination may spread more widely but with fast decreasing through...

Typologie de la flottille chalutière du port de Sète par une méthode de segmentation
Provedor de dados: 5
Autores: Taquet, Marc; Gaertner, Jean-claude; Bertrand, Jacques.
This work aims to define a typology of trawler f1eet in Sète, the main fishing harbour along the French Mediterranean coast, using several multivariate analysis methods. The fishing ships taken to account are represented by annual profiles of landing specific compositions. Five fishing strategies have been identified. A segmentation method using symbolic objects allows a formaI characterisation of the different strategies. These strategies are studied according to several general characteristics usually used for management rules elaboration (power, length, ship age). The typological analysis allows to characterise two main exploitation ways, one directed to the catch of a few species (Engraulis encrasicolus, Sardina pilchardus), the other characterised by...

Trois saisons de pêche aux casiers (1977 à 1979) dans le secteur de Flamanville
Provedor de dados: 5
Autores: Bertrand, Jacques.
La pêche des crustacés aux casiers constitue une part très importante de l'activité des navires (du doris au petit chalutier ponté) travaillant entre la pointe du Rozel et le cap de La Hague. Elle est pratiquée sur une période s'étendant de mars à octobre, les limites variant sensiblement suivant les années. Les activités de quatre des dix bateaux travaillant dans le secteur ont été suivies régulièrement par le relevé de carnets de pêche remplis quotidiennement par les pêcheurs. Ces quatres unités constituent un échantillonnage assez large de la flottille : du doris (environ 60 casiers) au petit chalutier (environ 400 casiers) en passant par le picoteux (environ 150 casiers) ; de ce fait on présente les différentes techniques de travail utilisées.

Estimateurs d'indices d'abondance dans le cas d'échantillonnages stratifiés
Provedor de dados: 5
Autores: Bertrand, Jacques; Chevalier, Robert.
One of the primary uses of trawl survey data is the estimation of abundance of the species involved. But these direct estimates give results with generally a high variability. Reducing this latter is one of the main problems for the scientists involved in such a research. Methods to achieve a better efficiency have been implemented. Nevertheless estimations remain highly variable, so the information on the changes in population, enclosed in the observed series of survey indices is mixed with a noise component result of both the survey sampling variability and effect of uncontrolled factors. PENNING'roN ( 1985) proposed time series models to filter measurement error from the signal. However the length of the series does not always allow using time series...

Spatio-temporal organization patterns of demersal assemblages of the east coast of Corsica (Mediterranean Sea)
Provedor de dados: 5
Autores: Gaertner, Jean-claude; Bertrand, Jacques; Samani, D; Souplet, Arnauld.
The paper deals with the spatio-temporal organization patterns demersal assemblages along the east coast of Corsica. We analysed data collected by the first standardized experimental bottom trawl surveys performed in this region from 1994 to 1999 (MEDITS programme). The use of a multiway table method (STATIS-CoA) showed that the spatial organization pattern of the demersal assemblages of eastern Corsica was highly stable during the period studied. This pattern was structured around three bathymetric areas (i) the continental shelf (between 50 to 200 m depth), (ii) the upper slope (from 200 to 500 m) and (iii) the deeper slope (from 500 to 800 m), but it did not show any heterogeneity in relation with latitude. Along the cast coast of Corsica-characterized...

P&gt;1. The development of ecosystem approaches to environmental management implies the need to account for multiple pressures on ecosystems. Trends in multiple metrics that respond differently to changes in major environmental pressures need to be combined to evaluate the impacts of fishing and environmental changes on fish communities. 2. An exploited fish community is viewed as a three-level food chain in which the two upper levels, or functional groups, are targeted by fishing fleets, while the lowest level is subject to environmental variation. Qualitative modelling is used to predict changes at the two upper levels, that is, top-down vs. bottom-up perturbations. Abundance and length metrics are calculated from survey data for 14 Mediterranean and...

The scientist community, the fishing organisations and all involved parties show a growing interest in an integrated project management of the sea space exploited by fishing communities. A key to reach such a target is to make available reliable and precise scientist data on the different components of the fishing systems.  For about twenty years, and in its mission to support the development of an integrated management for a sustainable use of marine resources, Ifremer has been organising monitoring campaigns of fishery resources along the shores of France. These campaigns aim at providing abundance indicator on species of interest. They consequently provide an essential knowledge base to characterize and trace the status of exploited fish and...
