As of 1985, Ifremer set up a selection programme for resistance to the protozoan Bonamia ostreae in European flat oysters (Ostrea edulis). Two selection lines, L85 and L89, from the third and second generation, respectively, were produced with 17 and 21 different families. The experimental design also included a mixed line (L85 x L89) of seven families and a control line of five families from Quiberon broodstock maintained without selection pressure.

Population bottleneck and effective size in Bonamia ostreae-resistant populations of Ostrea edulis as inferred by microsatellite markers

Autores: Launey, Sophie; Barre, Marc; Gerard, Andre; Naciri, Yamama.
Genetic variability at five microsatellite loci was analysed in three hatchery-propagated populations of the flat oyster, Ostrea edulis. These populations were part of a selection programme for resistance to the protozoan parasite Bonamia ostreae and were produced by mass spawns, without control of the genealogy. Evidence for population bottlenecks and inbreeding was sought. A reduction in the number of alleles, mainly due to the loss of rare alleles, was observed in all selected populations, relative to the natural population from which they were derived. Heterozygote excesses were observed in two populations, and were attributed to substructuring of the population into a small number of families. Pedigree reconstruction showed that these two populations...

Historique, expériences en cours et perspectives du programme de sélection de l'huître plate Ostrea edulis pour la résistance à la bonamiose

The Aquaculture and Pathological Genetics (GAP) laboratory at La Tremblade has been monitoring three populations of European flat oyster since 1985 or 1989 under selection for higher survival rates in the presence of the parasite Bonamia ostrea. One selection cycle (1985 population) or two (1989 populations) were carried out by mass selection by placing the oysters for several years in a highly infested zone, and then harvesting spawns from survivors.

Genetic improvement and selection in shellfish : a review based on oyster research and production
Provedor de dados: 5
Autores: Boudry, Pierre; Barre, Marc; Gerard, Andre.
Despite the economic importance of shellfish, genetic improvement has not yet had a great impact on these species. Shellfish farming is traditionally based on wild species whose natural populations are often overexploited and do not fulfill market demand. Up to now, the most effective answer to disease problems or for the improvement of productivity has been the introduction of new species. However, the introduction of new species is constrained by their ecological impact and is also limited by the availability of suitable species. Genetic improvement of local species should therefore be of great importance as a viable alternative for the long term sustainability of the shellfish industry. The different approaches to genetic improvement include...
