Researchers map genome of farmed mussel species
“This research project marks a significant advancement in aquaculture” – Tim Regan.
A complete genome map of the blue mussel (Mytilus edulis) has been created by researchers at the Roslin Institute in collaboration with Atlantic Aqua Farms.
The blue mussel is an important commercial aquaculture species in Europe and North America. At the world’s only commercial mussel hatchery on Prince Edward Island, Canada, the findings could help farmers to select mussels with desirable traits to breed.
The data could be used for targeted breeding programmes to improve disease resistance, reducing the loss of mussels to illness and improving the health and sustainability of populations.
The findings could also allow farmers to select for qualities that will could improve productivity, such as stronger byssus threads. These are important for mussels to securely attach to ropes, allowing for a more stable yield. Mussels could also be selected for faster rates of growth and to produce more meat.
As well as potentially benefitting the aquaculture industry, the genome map could also contribute to the conservation of wild populations.
Because blue mussels are able to spread and become established in non-native regions, genomic data could help scientists to track the spread of mussel populations and potentially mitigate the impact they have on local ecosystems.
The research team plans to continue their research by looking into the genetic diversity of blue mussels in Scotland.
Tim Regan, a career track fellow at the Roslin Institute, said: “This research project marks a significant advancement in aquaculture. It showcases how genomic research can provide practical solutions for commercial aquaculture and environmental conservation.”
The study has been published in the journal G3 Genes, Genomes, Genetics.
