Dynamique temporelle de la contribution du repeuplement en stades précoces de truite (Salmo Trutta l.) dans la population en place et dans la pêche sur le doubs franco-suisse.

Autores: Champigneulle, A.; Degiorgi, F.; Raymond, J. C.; Cachera, S.
The technique of otoliths fluoromarking has been used to evaluate at a large scale the practices of brown trout (Salmo trutta L.) stocking (540 000 - 570 000/year, most of them as sac fry) for three cohorts 1994-95-96 in a part of the River Doubs having a length of 40 km and fragmented in three zones (upstream, median, downstream) by three hydroelectric dams. For each of the three cohorts, there is a rather high contribution (23 to 60% according to the zone) of the stocked fry to the automnal 0+ standing population. The mass marking of all the stocked fry allowed to show that the dynamics of the contribution of the two components of recruitment (natural or stocked) differed. Indeed, the contribution of stocking decreased with time when measured in the...

Croissance de la coque (Cerastoderma edule) en baie de Somme : Morphométrie et Marquage
Provedor de dados: 5
Autores: Bellamy, Elise; Lefebvre, Alain; Mahe, Kelig; De Rafelis, Marc.
The bay of Somme is the first French field of cockles (Cerastoderma edule) with a production amounting to 3000 tons per year on average. In order to improve the stock management, it is necessary to increase our knowledge of this species. This study is looking at the growth of the common cockle. First, was carried out a morphometric analysis of the two left and right valves, which has revealed a perfect symmetry of the shell and has allowed us to establish strong correlations among the morphometric parameters. Then, a chemical marking study has been realized with calcein and manganese in order to obtain the exact growth. Calcein marking has showed a fluorescent stria only for an half hour immersion time at 150 mg.L-1. Likewise, the manganese marking has...

Revealing pelagic habitat use: the tagging of Pacific pelagics program
Provedor de dados: 5
Autores: Block, Ba; Costa, Dp; Boehlert, Gw; Kochevar, Re.
Tagging of Pacific pelagics (TOPP) is a pilot program of the Census of marine life (CoML) that will lead to understanding of pelagic habitat use by marine vertebrates and large squid in the North Pacific. Taking a multispecies approach, the TOPP project will use a range of electronic tag technologies to put the distribution and behavior of pelagic organisms, in the context of the oceanography of the North Pacific. Tag-bearing animals will be used as autonomous ocean profilers to enhance sparse oceanographic observations for vast ocean regions. These autonomous ocean samplers will provide unprecedented coverage of the water column structure of the North Pacific. The temporal and spatial data generated by this project will provide an "organism-eye" view of...

Traits biologiques et exploitation du bar commun Dicentrarchus labrax (L.) dans les pêcheries françaises de la Manche et du golfe de Gascogne.
Provedor de dados: 5
Autores: Fritsch, Manon.
Sea bass Dicentrarchus labrax (Linné, 1758) is a fish of major interest in France and in the British Isles. It is the main target species for some anglers and a growing number of professional fishermen. In spite of this, the reproduction of sea bass in natural environment, the identification of its populations, as well as the fleet participating to and the level of its exploitation are poorly known. Thus, in the perspective of a future management of the bass fisheries, this thesis collected required data for the analysis of the sea bass resource in the English Channel and the Bay of Biscay. A first chapter describes to the principal biological and ecological characteristics of Dicentrarchus labrax. The five following chapters deal successively with: (i)...

Estimation du nombre de tortues vertes femelles adultes Chelonia mydas par saison de ponte à Tromelin et Europa (Océan Indien) (1973-1985)
Provedor de dados: 5
Autores: Le Gall, Jean-yves; Bosc, Pierre; Taquet, Marc.
A research programm on the marine green turtle Chelonia mydas nesting on the two major reproduction sites for the species in the Indian Ocean, conducled over last 15 years, included intensive tagging programm. Processing of these lagging data provides estimations of adult female populations {or each site and season from two independent methods. First classical method is the ratio of total number of nests produced over a define time on the mean individual number of nests by female during the same time (November, December, January). The computed mean individual number ranges from 3 to 3.5 obtained over 2 to 3 months. The second method is the multiple capture-recapture method (JOLLY, 1965; SEBER, 1965; MANLY, 1984). Il is an original tentative of applying...

Manuel des protocoles de campagne halieutique. Campagnes de surveillance de la pêche côtière des crustacés du site de Flamanville CRUSTAFLAM
Provedor de dados: 5
Autores: Schlaich, Ivan; Miossec, Dominique.
Fishery and ecological studies have been carried out by Ifremer as part of the environnement monitoring of the nuclear power plant of Flamanville ( programme supported by "Electricité de France"). Their aim is to follow the natural fluctuations of the major species in the previous years and evaluate the impact of the power plant on the local fishery from the moment it has begun to operate. This paper presents the data collected between 1977 and 2002 and the creation of a naturel reserve which induced a modification of the relative index calculation and the introduction of a precise lobster numbering in the reserve. These points are described here with the sampling methodology and the tagging technique used. The associated data base specification is given...
