RESIPAL applies genomic tools to initiate marker-assisted selection or genomic selection under controlled conditions for tolerance/resistance to brown ring disease in Manila clams. In this project, we also seek to develop non-lethal diagnostic methods for the detection of the pathogen (Vibrio tapetis) in infected individuals in the laboratory, allowing the selection and breeding of individuals that exhibit resistance traits to this infection. Furthermore, this experiment will be conducted over several generations, allowing to provide a solid basis for the design of a breeding programme that can be used in European hatcheries. Finally, the genetic gain between disease resistance traits and commercial and production traits will be evaluated with the aim of balancing the gains from this genetic selection.

This project is linked to and builds on currently ongoing research projects such as the European H2020 project VIVALDI in which all RESIPAL partners are involved (SYSAAF, SATMAR).
