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...

Caracteristiques du stock de saumon atlantique (Salmo salar L.) capture a la ligne sur l'Aulne (riviere de Bretagne nord) durant la periode 1983-1981.

Study of fish caught by angling on the Aulne River from 1973 to 1981provides information on the characteristics of Atlantic salmon (Salmo salar) populations and on the characteristics of the fishery. A discontinuity was noted in 1973 in the catch evolution that separates two periods: 1955-1972 (630 salmons each year) and 1973-1981 (161 salmons each years).

Traits biologiques et exploitation du bar commun Dicentrarchus labrax (L.) dans les pêcheries françaises de la Manche et du golfe de Gascogne.

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)...

Comparative analysis of phylogenetic and fishing effects in life history patterns of teleost fishes
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Rochet, Marie-joelle; Cornillon, Pierre-andré; Sabatier, Robert; Pontier, Dominique.
The effects of fishing on life history traits and life history strategies of teleost fishes are analysed by a new comparative method that splits traits into an allometric part (size effect), an autoregressive phylogenetic component, and an environmental component (fishing effect). Both intra- and inter-specific variation of age and size at maturity, fecundity, adult size and egg size are analysed by comparing 84 populations of 49 species submitted to various fishing pressures. Two axes of life history diversification are found among teleosts. One is the well-known slow-fast continuum separating short-lived and early maturing species (like Clupeiformes) From longer-lived species that mature late relative to their size and spawn larger eggs (like salmonids...
