Analyse des comportements financiers des entreprises et essais de typologie dans le secteur des peches artisanales ArchiMer
Foucault, François; Gerinette, Valérie; Lemaire, Catherine.
(Not controled OCR) The economic results of artisanal fishing enterprises are investigated through a sample of 300 to 700 artisanal vessels for which account books. The use of economic (such as added value) and financial ratios (solvency and financial autonomy) leads to identification of four groups of firms. Over the period, financial rentability and autonomy show obvious damaging that underlines the relance of a (current) analysis on the impact of public subsidies on the enterprises behaviour.

Analyse des resultats et des comportements economiques des entreprises de peche artisanale ArchiMer
Catanzano, Joseph; Gilly, Bernard; Lantz, Frederic; Durand, M.h..
(Not controled OCR) The economic results of artisanal fishing enterprises are investigated through a sample of 300 to 700 artisanal vessels for which account books are available from 1983 to 1986. The use of economic (such as added value) and financial ratios (solvency and financial autonomy) leads to the identification of four groups of firms. A rough classification has been identified from gears used and areas. Over the period, financial rentability and autonomy show obvious damaging that underlines the relevance of a (current) analysis on the impact of public subsidies on the enterprises behaviour.

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...

Distribution spatiale des stocks de poissons récifaux démersaux d'intérêt commercial et effort de pêche en Province Nord de Nouvelle-Calédonie (Pacifique occidental) ArchiMer
Letourneur, Yves; Labrosse, Pierre; Kulbicki, Michel.
Fish from lagoon and reef in New Caledonia are mainly caught by artisanal fisheries and subsistence fishing. The present study aimed at estimating these fish standing stocks, at finding the main factors influencing the spatial distribution of these fish, and at estimating the maximum sustainable yield with considerations for socio-economic aspects sensu late. A total of 1406 stations was surveyed in the Northern Province of New Caledonia. Sampling was stratified according to three zones (north, east and west) and three biotopes (coral reefs, near-reef areas and lagoon bottoms). This work demonstrates the existence of important fish stocks of commercial interest in reefal and lagoonal waters of the Northern Province, estimated at about 138 300 t. The...

Etude de la qualité des captures de la pêcherie associée aux DCP ancrés. Projet MAGDELESA ArchiMer
Dromer, Clément; Eugene, Sonia; Régina, Françoise; Reynal, Lionel; Etienne, Monique; Mathieu, Heloïse; Pau, Cedric.
Product quality is an element of sustainable development for fisheries because it guarantees the safety and quality of landings, as well as optimal uptake. Where FADs fishing is concerned, open boats used for the capture of large pelagic fish are not big enough to be equipped with sufficient (regulatory) catch preservation equipment. In collaboration with boats at sea, this study has made it possible to monitor landings and fish flesh analysis and to review fishing practices and their subsequent impact on the quality of FADs fishing products. Several post-capture treatment protocols have been implemented by fishermen based on their professional knowledge, the size of the catch or the facilities at their disposal on the boats. Observations at sea have...

Etude technico-économique sur les DCP côtiers ancrés de La Réunion. Rapport final ArchiMer
Guyomard, David; Hohmann, Sandra; Fleury, Pierre-gildas; Bissery, Claire.
Reconnus dans toute la zone intertropicale comme outils d'aménagement incontournables des petites pêches côtières, les DCP (Dispositifs de Concentration de Poissons) ont été implantés autour de La Réunion à partir de 1988 et gérés collectivement par le Comité Régional des Pêches. Ces DCP côtiers, ancrés à quelques milles des ports de pêche ont permis un redéploiement d'une grande partie de l'effort de pêche vers les espèces pélagiques du large, diminuant ainsi la pression exercée sur les espèces récifales côtières. La présente étude a pour objectifs de mettre à jour les connaissances techniques et économiques sur le "système DCP", autour des pêcheurs, de la pêche sur DCP et des DCP eux-mêmes. Une enquête des usages et des perceptions des pêcheurs vis-à-vis...

Grands pélagiques et Dispositifs de Concentration de Poissons (DCP) en Martinique (Antilles françaises) ArchiMer
Taquet, Marc.
Les ressources récifales et côtières du plateau insulaire de la Martinique subissent une pression anthropique croissante et ne sont plus en mesure d'assurer un revenu suffisant aux pêcheurs professionnels. La présente étude a pour objectif d'accompagner le redéploiement de l'activité de la flottille martiniquaise de proximité vers l'exploitation des ressources en grands poissons pélagiques à l'aide de dispositifs de concentration de poissons (DCP), sans imposer un changement d'échelle des unités d'exploitation. Les travaux sont développés selon deux axes complémentaires (i) l'amélioration technologique des DCP, (ii) une meilleure connaissance de la biologie des grands poissons pélagiques exploitables dans la zone d'activité de la flottille. La modélisation...

Investment and factor remuneration in small-scale fisheries ArchiMer
Lantz, Frederic; Junqueira-lopez, R.
Investment behaviour is a complex process which plays a major role in fisheries dynamics because it determines the size of the fishing fleet. The purpose of this paper is to examine the consequences of the main characteristics of fishing activity on investment. The theoretical dynamic model of a fishery shows us the "bangbang" pallern of investment. Furthermore, fishing activity has a high intrinsic variability. Thus, the system in which income is shared between the crew and the ship owner is also considered as a way of sharing risks and so reducing the variability ofinvestment return. Finally, the type of investment financing (subsidies, loans) can strongly stimulate fisheries dynamics but can also have some undesirable effects. [NOT CONTROLLED OCR]

La pêche artisanale des années quatre-vingt en France ArchiMer
Catanzano, Joseph; Lantz, Frederic; Vernier, C; Allard, M.o.
The artisanal fisheries industry has experienced a major development over the 80's: technology has improved and ship building costs have increased. The firms' economic behaviour and financial performances have shown that the marginal profitability of capital is lower for large units than for small units, the latter being used by coastal fisheries. Overall, conclusions on the financial situation of the industry must be qualified. Public intervention has materialized through (1) an increasing amount of state aids supporting modernization investment (Brittany being the most supported region), (2) more political and financial involvement of regions as a result of more administrative and decision making responsibilities being devolved to them, (3) the...

Le répulsif à cétacés : performances acoustiques requises ArchiMer
Le Gall, Yves; Origne, Laurent; Scalabrin, Carla; Morizur, Yvon.
Acoustic deterrent devices could be an appealing solution to tackle accidental cetacean by-catches in pelagic trawls or in fishing net gears. The bibliographical data on two species (Harbour porpoise and bottlenosed dolphin) have been analyzed in terms of audiogram, discomfort noise level that could lead to behavioural changes, sensory fatigue, and threshold for permanent hearing injuries. It is possible, on the basis of the above data, to characterize an efficient annoyance sound threshold which is not harmful to the species to be protected. Taking into account the properties of the sound waves propagation in the marine environment and according to the required range, the minimal amplitude of the repulsive sound to emit is proposed. Accordingly, the...

L’environnement, les ressources et les pêcheries de la ZEE mauritanienne OceanDocs
Girardin, M.; Chavance, P..
Les traits majeurs de l’environnement de la ZEE mauritanienne sont décrits dans le premier chapitre, tandis que le second trace les caractéristiques essentielles de l’écobiologie des espèces susceptibles d’être la cible de flottilles. Ces deux premières parties ont pour but de définir le cadre naturel dans le quel évoluent les flottilles de pêche. Ces dernières sont décrites dans un troisième chapitre en retenant leurs caractéristiques essentielles dépouillées des éléments jugés conjoncturels et anecdotiques. En conclusion, le document s'efforce de tirer quelques enseignements utiles à la recherche et à la gestion.

Les pêches artisanales de la Manche Orientale. Flottilles et ressources halieutiques ArchiMer
Lemoine, Michel; Giret, Marc.
From Normandy to Belgium bordary, the coastal fishery became during the ten last years a significant social and economic actor, which mostly lives by predominant exploitation of Eastern Channel. Recently discovering a situation of resource overexploitation and a difficult cohabitation between "metiers", these coastal fleets are in the heart of various preoccupations of managment at regional, national and european levels. Since 1985, a coordinated programme (including Boulogne and Ouistreham) allowed to progress in the knowledge of complex fisheries through : improvement of statistics, characterisation of coastal fleets and their activity, asses-ment of the knowledge on the resources.This synthesis describes, for 1987-1988, the quality of the regional...

Pêche et riziculture au Surinam. Impact de la riziculture sur les ressources halieutiques ArchiMer
Dintheer, Christian; Abbes, Rene; Fritsch, Jean-marie.
La pêche et la riziculture font partie des secteurs économiques les plus importants du Surinam. Depuis près de 30 ans, la riziculture par poldérisation des zones basses et marécageuses a permis de mettre en valeur toute la bande littorale de l’ouest du pays ; cette culture s’accroit encore aujourd’hui de façon significative. Le secteur halieutique quant à lui regroupe d’une part une pêche industrielle exploitant les crevettes du plateau continental et d’autre part une pêche artisanale traditionnelle qui recherche essentiellement les poissons sur les petits fonds côtiers et dans les marais saumâtres.

Typologie des entreprises de peche artisanale ArchiMer
Gilly, Bernard; Lantz, Frederic.
The document introduces a typology of small fishing companies from the Finistère area based on a factorial analysis of multiple correspondences. This typology is an integral part of the continuation of the study conducted on the economic analysis of small fishing companies. The analysis in multiple components is performed by using the economic criteria of profitability and investment as elements, and as additional variables the structural characteristics (techniques) of the companies. The analysis makes it possible to differentiate companies by their financial parameters on the one hand, and their operating income on the other hand.
