Última Metamorphosis and estuarine colonisation in the common sole, Solea solea (L.): implications for recruitment regulation ArchiMer Amara, Rachid; Lagardere, Francoise; Desaunay, Yves; Marchand, Jocelyne. Processes involved in both metamorphosis and settlement of young sole were studied at the population, cohort and individual level in order to evaluate their role in survival and recruitment regulation. Metamorphosis can be defined as a phase of variable duration (10 days on average) at the end of which the larval period of pelagic dissemination is completed. Size at the onset of metamorphosis is considerably less variable than age and is less plastic to environmental change. Metamorphosis is triggered by the acquisition of a competent size and a sufficient store of energy supplies, and occurs without a nutritional crisis or growth arrest. In addition, changes in organogenesis and behaviour that occur during metamorphosis seem to contribute to horizontal...

(Haplosporida - Haplospordiidae) chez le xanthide Rhithropanopeus Harrisii (Gould) tridentatus (Maitland) dans le canal de Caen a la mer. ArchiMer Marchand, Jocelyne. Continuous observations of a natural population of R.harrisii tridentatus in the canal from Caen to the sea, and dissections of these crabs permitted the discovery of a protozoan parasite belonging to the fam Haplosporidiidae: Minchinia sp. The parasite exists in the American sp R.harrisii in Chesapeake Bay. The sporocysts are localized in the gills, muscles, general cavity, appendages and pericardial sinus. The harmful action of Minchinia sp. induced an important reduction of R.h.tridentatus population on behalf of a Carcinus maenas one, inversions of sex-ratio and a diminution of the numbers of young crabs (<5.5 mm) imperilling the future of the Xanthid population.

Ano: 1974 URL: http://archimer.ifremer.fr/doc/1974/publication-2042.pdf Bionomie benthique de l'estuaire de la Loire. I. Observations sur l'estran maritime de la mer a Cordemais. ArchiMer Marchand, Jocelyne. This study was the first to be undertaken since 1901, since when natural and industrial changes had occurred to affect the habitat. Observations are reported here for the banks of the north and south shores, using certain points as reference. Features of the 2 shores are described, and an inventory given of the fauna of the banks. Hydrozoan Cnidaria, Bryozoans, Annelids, Molluscs, Crustacea and fish are listed with notes, and particular attention is given to the crabs found (Rhithropanopeus harrisii tridentatus). The monthly distribution of crab sizes and sexes is given, and the species of animals found in association with crabs is shown to vary according to the site studied. The percentage of female crabs found to be fertile each month was investigated,... Tipo: Text Palavras-chave: Crustacea and fish; Molluscs; Fauna; Habitat; Observation; Loire; Benthic bionomy.
