Mise en place d'un plan de sélection génétique pour l'ormeau européen Haliotis tuberculata
Provedor de dados: 5
Autores: Lachambre, Sébastien.
In the context of an increasing demand and a declining supply from fisheries, worldwide aquaculture production of abalone has greatly increased in the last decades. Selective breeding has been initiated to improve growth in major abalone species. In France, the abalone production was initiated 30 years ago and struggles to develop. This CIFRE PhD co-financed by France Haliotis, the only French hatchery in activity, was initiated to study early domestication process of farmed abalone population and to provide knowledge required to design a selective breeding program adapted to this company. Wild and farmed populations were compared, showing that, until 2013, farmed and wild abalone presented similar performances. However, lower physiological and behavioural...

Estimation du stock naturel d'ormeaux du golfe du Morbihan
Provedor de dados: 5
Autores: Billy, Stéphanie; Peronnet, Isabelle; Salaun, Michele.
The Gulf has very tiled sea beds, and the surface areas of habitats suitable for ormer populations are rather reduced (1.56km2). Three zones have ormer densities of interest from the point of view of profitability, Brannec, lrus and Creizig. But since their surface area is not great, the exploitable biomass, that corresponding to individuals of a size greater than 80mm (legal catch size), is average. These three zones would be exploitable but following a limited fishing effort. The sectors of Ile aux moines and Jument and Henn Tenn show average to low densities and are not therefore exploitable in a profitable way. Finally, Gavrinis and le Logeo have revealed low densities of ormers, this could be due to an intensive illegal exploitation. In fact, many...

Les mortalités d'ormeaux en Bretagne et Normandie : mise en évidence de l'agent causal
Provedor de dados: 5
Autores: Basuyaux, Olivier; Nicolas, Jean-louis; Mazurie, Joseph; Thebault, Anne.
In summer 1997, massive abalone Haliotis tuberculata mortalities are monitored on the coast of Brittany, near Concarneau. They then spread out to the north of Brittany (1998) and to the Norman-Breton Bay in 1999. 60 to 80 % of the abalone populations died without any noticeable symptoms. In 1999, these mortalities reached cultivated abalones at the SMEL hatchery (Blainville). A septicemic bacteria was isolated from every organ (muscle, mucus gland, haemolymph ...) collected from abalones that had just died.
