Observations sur l'état des stocks démersaux des accores du golfe du Lion
Provedor de dados: 5
Autores: Campillo, Albert; Dremiere, Pierre-yves.
The areas of the continental shelf neighbouring the valleys and deep sectors of the slope of the gulf of Lion, are hardly or not at all exploited by the French fleet, especially in its central and eastern part, for multiple reasons: distance from the coast, high fuel expenses, meeting the times set, complexity of the canyons' and their surroundings' morphology, mistral wind frequently blowing. This study aims to define the fisheries located on the flexure and the slope on the three following areas: east of Port-Vendres, south of Sète, south of the gulf of Fos, in order to compare their status, as far as performances and the composition, in size, of the most represented species are concerned.

Efficiency of the bottom trawl used for the Mediterranean international trawl survey (MEDITS)
Provedor de dados: 5
Autores: Fiorentini, Loris; Dremiere, Pierre-yves; Leonori, Iole; Sala, Antonello; Palumbo, Vito.
The aim of the work presented in this paper was to assess the relative efficiency of the GOC 73 sampling trawl used for the Mediterranean international trawl survey programme (MEDITS) compared with that of a typical Italian commercial trawl. The latter was chosen because it is commonly used by fishermen in the central Adriatic, where the experiment was conducted, and therefore appeared as the best possible sampler of the commercial species present in those areas. Moreover, this trawl is similar to the various trawls used for the Italian national survey programme (GRUND). Four fishing trips were conducted between 1996 and 1997 in different areas and seasons to sample different species. Each trip was conducted in the same fishing area. A codend cover mounted...

Les Systèmes de licences de pêche : le cas de la Méditerranée française
Provedor de dados: 5
Autores: Meuriot, Eric; Dremiere, Pierre-yves.
The subject of this study is to examine the operation and implications of the system of licenses for bottom trawling implemented in the French Mediterranean, this compared with the context of fishing in this area during the last twenty years. The study begins with a review and assessment of the evaluation criteria proposed in the economic literature. This review of the literature is done to find an approach for analysing licensing systems. The study then recounts the main stages of the implementation of the licensing system for trawling in the Mediterranean as well as the context of fishing. After a description of the licensing system and a reminder of the objectives and arguments defended by the various participating groups, the study examines its...

Evolution economique du chalutage en Méditerranée. Le cas du port de Sète (1970-1974)
Provedor de dados: 5
Autores: Meuriot, Eric; Dremiere, Pierre-yves.
The trawling activities of Sète ships grew markedly between 1971 and 1983: the number and above all the power of these trawls increased; marketed amounts went from less than 3,000 tonnes for the period 1971-1973 to more than 8,000 tonnes in 1982 and 1983. This development masks a distinct deterioration of the economic results of each category of trawl since the end of the 1970s. This deterioration results from the increase of certain operating expenses, like fuel and ENIM fees; it is also due to a tendency towards decreasing, since the mid-1970s, the intake of demersal species per unit of effort. The adaptations to the decrease of intake per unit of effort were made by increasing motor power, by a relative specialisation of 24-to-25-metre trawls in small...

L'impact d'une politique de limitation de l'effort de peche : Les chalutiers méditerranéens et le système des licences
Provedor de dados: 5
Autores: Meuriot, Eric; Dremiere, Pierre-yves.
Many theoretical studies since after the war have been devoted to the biological and economic aspects of exploiting halieutic resources. They often lead to, indeed focus directly on, the interest of limiting the fishing effort. In the simplest case, the one in which production automatically finds an outlet, the idea of limiting the fishing effort comes from an argument that can be presented schematically in three points:  a) halieutic resources and their renewal are limited; b) an increase in overall fishing effort cannot therefore be done while maintaining the same level of catches per unit of effort; the latter inevitably decrease. Additionally, beyond a certain level of fishing intensity, a supplementary increase of the overall fishing effort brings...

Résultat de la campagne de pêche au chalut pélagique réalisée à Sète durant l'année 1977
Provedor de dados: 5
Autores: Pichot, Paul; Dremiere, Pierre-yves.
Depuis 1970, année record de la production sardinière en Méditerranée (plus de 22 000 t dont 21 000 t en provenance des quartiers de Port-Vendres, Sète, Martigues et Marseille), la pêche de la sardine s'est trouvée confrontée à de nombreuses difficultés. Avec une production proche de 11 000 t seulement, la campagne sardinière 1976 s'est inscrite dans la ligne d'un certain déclin de la pêche de ce petit pélagique qui, se manifestant depuis six ans, a ramené le niveau de production à celui des années 1960-1965, période de début du développement et d'organisation de cette activité.

Sélectivité des chaluts à 4 faces en Méditerranée. Rapport d'étude d'avant-projet, 1992
Provedor de dados: 5
Autores: Dremiere, Pierre-yves; Burgaud, Laurence.
On the French Mediterranean coasts, trawl fishing used to be practiced exclusively with two-sided nets until the middle of the 1970s. The adoption of four-sided trawls has changed the composition of species and sizes of the trawlers'catches in this area. Experimental fisheries conducted in the Gulf of Lion on board a research vessel belonging to the IFREMER enabled the study of the selectivity parameters of a four-sided bottom trawl with a wrapping double-pocket. Three pockets of different meshes were tried out on various demersal and pelagic species. The collected data was processed through different selectivity analysis methods. Presented here is an assessment of the relative efficiency of each of these seven methods.

Compte rendu de la campagne de pêche au chalut pélagique réalisée par l'"Ichthys" sur les côtes tunisiennes (27 septembre - 2 novembre 1977)
Provedor de dados: 5
Autores: Dremiere, Pierre-yves.
L'exploitation des stocks de petits pélagiques est traditionnellement réalisée en Tunisie par des navires pratiquant la pêche au feu. La campagne de l'"Ichthys", dont le programme initial avait été établi dans le cadre d'un accord passé avec l'Office National des Pêches de Tunisie, avait pour but de montrer les possibilités de pêche de jour au moyen d'un chalut pélagique à grandes mailles. Les travaux devaient être effectués d'une part dans les zones habituelles de pêche au feu, d'autre part dans les secteurs actuellement peu ou pas fréquentés par les senneurs tunisiens, notamment le golfe de Gabès. C'est dans cette dernière zone que des essais préliminaires de pêche au chalut pélagique avaient déjà été effectués par la "Thalassa" du 6 novembre au 6...

Escapement from the main body of the bottom trawl used for the Mediterranean international trawl survey (MEDITS)
Provedor de dados: 5
Autores: Dremiere, Pierre-yves; Fiorentini, Loris; Cosimi, Giulio; Leonori, Iole; Sala, Antonello; Spagnolo, Alessandra.
Escapement through the body or under the footrope of the sampling trawl used for the Mediterranean international trawl survey programme (MEDITS) was assessed i) by means of visual observations performed with a towed operating vehicle equipped with a high-sensitivity video camera, and ii) by attaching small bags to the outside of the trawl body and under the footrope. Due to the small size of most of the individuals present in the study area and to the towing speed, fish behaviour in front of the trawl could not be frequently observed. In contrast, their behaviour was easily observed inside the net, especially upstream and inside the codend. Some species, such as horse mackerel (trachurus sp.), showed greater swimming endurance compared with others such as...
