Última Détermination de l'âge et de la croissance de Buccinum undatum L. (Gasteropoda : Prosobranchia) à l'aide des isotopes stables de la coquille et de l'ornementation operculaire ArchiMer Santarelli, Leonardo; Gros, Philippe. This paper presents a simple method of individual age determination of the gastropod Buccinum undatum, based on the counting of operculum striae. The validation of this method is achieved by the use of several unrelated approaches. As a first step, oxygen stable isotopie analysis is used to check shell records of seasonal temperature fluctuations. We then establish a geometrie correspondence between simultaneously elaborated parts of the shell and the operculum, and show that the mean periodicity of operculum striae formation is annual. With the help of complementary data collected on the fishing grounds, and also of a biometrical study, it is further shown that the age criterion is marked during the warmer months of the year, between June and October....

These studies of halieutic ecology produced at the request of Electricité de France by the French Institute of Research for Exploitation of the Sea in the Normand Breton Gulf must constitute one of the elements making it possible to come to a conclusion or not on the feasibility of the tidal power plant construction project; these studies have three parts: The first part discusses halieutic zooplankton. In the first place, the main species that constitute the exploitable living resources are considered, observed from the first stages of their life, in the egg or at different larval stages preceding the juvenile state. Also of interest are certain holoplanktonic groups. The whole of these observations establishes the status of zooplanktonic populations...

Ano: 1986 URL: http://archimer.ifremer.fr/doc/1986/rapport-2333.pdf Méthode d'estimation de la surface de pêche d'un casier à l'aide d'une filière expérimentale ArchiMer Gros, Philippe; Santarelli, Leonardo. The experimental design of the capture field area of baited whelk-pots involves, as a controlled factor, four different spacings between pots (6, 12, 24 and 36m), randomly distributed along a ground line. This spectrum of values is sufficiently broad to preclude overlap of capturing fields of sorne pots. Taking account of the patterns of the M2 tidal currents in the area studied, an ellipse was chosen as a geometrical model of the shape of the capture field. Semimajor and semiminor axes were estimated by least squares, the expected catch per pot being defined as a decreasing function of the area of overlap with adjacent capture fields. · Experimental fishing of Buccinum undatum L. was carried out in the Channel Isles region (Western Channel), and provided...
