Última Are commercial logbook and scientific CPUE data useful for characterizing the spatial and seasonal distribution of exploited populations? The case of the Celtic Sea whiting ArchiMer Verdoit, Marion; Pelletier, Dominique; Bellail, Robert. A statistical approach is proposed to utilize the information contained both in scientific surveys and commercial fishing logbooks, in order to determine spatial and temporal distributions of recruiting and spawning fish of exploited populations. The approach is based on multivariate descriptive methods including ordination methods and classification techniques. A typology involving a principal component analysis (PCA), followed by a hierarchical ascending classification (HAC), is applied to both scientific and commercial data. PCA that accounts for spatial and temporal contiguities were performed. These analyses allow to compare structures observed at global and local scales, with those observed without focusing on a particular scale. The method is...

Ano: 2003 URL: http://archimer.ifremer.fr/doc/2005/publication-335.pdf Combining indicator trends to assess ongoing changes in exploited fish communities: diagnostic of communities off the coasts of France ArchiMer Rochet, Marie-joelle; Trenkel, Verena; Bellail, Robert; Coppin, Franck; Le Pape, Olivier; Mahe, Jean-claude; Morin, Jocelyne; Poulard, Jean-charles; Schlaich, Ivan; Souplet, Arnauld; Verin, Yves; Bertrand, Jacques. 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...

Ano: 2005 URL: http://archimer.ifremer.fr/doc/2005/publication-773.pdf Observations ichtyologiques effectuées en 2003 ArchiMer Quero, Jean-claude; Bellail, Robert; Spitz, J. During 2003, one flying gurnard Dactylopterus volitans is recorded in southern Brittany. In 1995, we note the northward expansion to Brittany of Diplodus sargus in relation to the warming of water. The authors give some data on the diet of Liza aurata, Chelon labrosus and Torpedo nobiliana.

During 2004, Caranx crysos and Echeneis naucrates are caught in the Bay of Biscay, at north of their known repartition. The capture in our waters of two specimens of Cyttopsis rosea, the eighth specimen of Trachinotus ovatus and six Lagocephalus lagocephalus are mentioned.

Ano: 2005 URL: http://archimer.ifremer.fr/doc/2005/publication-3658.pdf Self-sampling of cod in the Celtic Sea ArchiMer Bellail, Robert; Peronnet, Isabelle; Rochet, Marie-joelle; Lamothe, Julien. Since 2003, the application of restrictive TAC for cod in area VIIb-k has led some French Professional Organisations to manage their restrictive quota by imitations of landings by trip or period or by prohibiting the landings of the smallest commercial category. In consequence of that, le level of discarding has increased by high grading practice. In the lack of available and reliable data to estimate the level of discarding and the amount of discarded fish, the assessment of Celtic Sea Cod in Divisions VIIe-k has been in recent years more and more uncertain, especially in estimating younger year classes, for a fishery which can be qualified as a recruitment fishery. On a Professional Organisation (PMA= Pêcheries Manche-Atlantique) initiative and in the...

Ce document présente l'état des principaux stocks exploités par les flottes françaises en termes de mortalité par pêche et de biomasse de reproducteurs. La situation fin 2010 (début 2011) par rapport aux points de référence (de précaution et Fmsy) est indiqué lorsque les indicateurs sont estimés et que les références sont définies. Les grandes tendances en matière d'évolution des mortalités et biomasses sont également indiquées.

This document presents all the techniques used in routine by Ifremer to estimate the age of fish from the calcified piece. The procedure for estimating age describes each technical stage from the taking of the calcified piece through to the supplying of key sizes/ages to the European work groups. This procedure is specific to each species and even each population of fish.
