Les mortalités d'ormeaux en Bretagne nord en 1998: synthèse des observations et analyses
Provedor de dados: 5
Autores: Mazurie, Joseph; Thebault, Anne; Le Mao, Patrick; Veron, Gerard; Tige, Gilbert; Richard, Olivier.
Des mortalités anormales d'ormeaux ont été signalées en Bretagne nord (départements d'Ille et Vilaine et Côtes d'Armor) à partir du mois d'août 1998 et porté atteinte à la pêcherie professionnelle de cette zone. Des mortalités de même type avaient été signalées en Bretagne Sud, l'année précédente. Les mortalités de 1998 ont épargné le secteur plus à l'ouest (le Finistère) et plus à l'est (la Normandie). Une estimation précise n'a pas été entreprise, mais les pertes signalées par endroits dépassent 50% du stock. Les ormeaux atteints, de toutes tailles, ne présentent pas de symptôme particulier. Les analyses histologiques réalisées en priorité n'ont pas révélé d'agent infectieux. Toutefois, dans le doute et devant le caractère évolutif du phénomène, une...

Interaction de la bactérie Vibrio harveyi avec son hôte, l'hormeau Haliotis tuberculata : approches physiologiques, cellulaires et moléculaires
Provedor de dados: 5
Autores: Travers, Marie-agnes.
Abalone aquaculture only recently developed in western Europe, but already it has to face numerous pathologies. Since 1998, the natural and farm stocks of Haliotis tuberculata suffer regularly high mortalities, mainly due to the pathogenic bacterium, Vibrio harveyi. The vibriosis of the European abalone, in particular its macroscopic signs, and the conditions necessary for its development have been studied in detail by field and laboratory experiments. We have been able to show the importance of the interplay between water temperature (&gt;17°C), animal physiology (reproduction period) and a pathogenic strain (harbouring the plasmid pVCR1) for the development of this abalone disease. A limited localisation study of the abalone target tissues (gills, muscle...

La reproduction de l'Ormeau Haliotis tuberculata L.
Provedor de dados: 5
Autores: Girard, Annie.
In order to improve the regulation of abalone 'fishing' and to provide for the restocking of supplies, more details of the reproductive cycle were sought. Attention is given to gonad morphology, acquisition of sexual maturity, juvenile hermaphroditism, gonad histogenesis and histology of gametogenesis, annual cycle of gamete emission, and the relation between size and fertility. Results are presented in graphs, histograms, diagrams and photographs. It was found that female reached sexual maturity during the 3rd year, at 38-54 mm, male during year 2 at 25-40 mm; there was successive juvenile hermaphroditism; an active period from mid-June to mid-November was indicated by the volumentric index of maturity; water temperature was associated with the...
