On Wednesday 14 January 2026, our S3 Biology pupils had the opportunity to visit the Cooke Aquaculture Quoys Hatchery in Unst, allowing them to see their classroom learning applied in a real-world work setting.

The class has been studying selective breeding, as well as how varying pH levels in water can affect aquatic life.

Aquaculture staff members demonstrated how a photometer is used for pH testing, and pupils were given an insight into how exceptional Scottish salmon are grown from egg to plate.

A big thank you to DYW Shetland for organising and Cooke Aquaculture for supporting the trip.
