New case study: AquaLeap - harnessing genetics to strengthen UK aquaculture

Advancing the boundaries of genomic technologies in four aquaculture species

This project applied genomic tools to improve breeding and stock quality for four species: Atlantic salmon, European lobster, European flat oyster, and lumpfish. These species represent both established and emerging industries, and the project aimed to tackle major challenges such as disease threats and animal welfare while supporting sustainable growth.

The partners were the Roslin Institute (University of Edinburgh), University of Aberdeen, University of Exeter, Institute of Aquaculture (University of Stirling), Xelect Ltd, Cefas, Hendrix Genetics, Otter Ferry Seafish and the National Lobster Hatchery. The funders were: BBSRC, NERC and SAIC and the project was valued at over £1.1M

Reference genomes were developed for lobster and flat oyster, created genetic marker panels, and explored structural variants - DNA changes that strongly influence traits like growth and disease resistance.

For salmon, researchers advanced gene-editing techniques targeting viral disease resilience, paving the way for future breakthroughs. Lumpfish studies assessed genetic diversity, while oyster research focused on disease resistance genes critical for restoration efforts. The project also considered ethical and regulatory aspects of gene editing, ensuring responsible innovation.

The full title of this project is ‘AquaLeap: Innovation in genetics and breeding to advance UK aquaculture production’.
