Development of eDNA tools for the detection of marine invasive non-native species to support European flat oyster (Ostrea edulis) restoration projects.
The European flat oyster ( Ostrea edulis ) is an important keystone species in Scottish coastal waters. However due to anthropogenic pressures, significant reductions to oyster beds have been observed across Europe. In Scotland, several projects are currently aiming to restore European flat oyster h...

The European flat oyster ( Ostrea edulis ) is an important keystone species in Scottish coastal waters. However due to anthropogenic pressures, significant reductions to oyster beds have been observed across Europe. In Scotland, several projects are currently aiming to restore European flat oyster habitats through the translocation of juvenile oysters from various sources including hatcheries and aquaculture. However, translocation of shellfish is not risk free and can increase the risk of accidental translocation of invasive non-native species (INNS). If INNS become established outside of their native range they can cause irreversible harm to native organisms and habitats. This study aims to develop molecular tools to detect environmental DNA of INNS which can be potentially associated with the translocation of live shellfish stocks. We have developed a species-specific real-time PCR assay for detection of Pacific oyster ( Crassostrea gigas) and tested its sensitivity in a large-scale replicated mesocosm based experiment with varying densities of C.gigas .
