Detecting the Invasive Species
Sgiath works with her owner, marine ecologist Dr Texa Sim, to locate colonies of the carpet sea squirt, formally known as Didemnum vexillum. The species, believed to have originated in Japan, arrived in the UK in 2008 and has since spread to several seaside locations. It can smother native species and clog aquaculture infrastructure, costing millions of pounds annually across Europe to manage.
According to the BBC, Sgiath is thought to be the UK's first sea squirt-hunting dog, while the Herald Scotland reports she is believed to be the first dog in the world trained to detect this specific organism. The dog uses her scent detection skills to find the sea squirt, which can be difficult to spot among seaweed and on structures like pontoons.
Dr Sim, based near Glencoe, initially trained Sgiath as a mountain rescue dog. She later adapted the dog's skills for marine conservation. "When I first started this project, I genuinely didn't know whether it would work," Sim said. "No one had really explored whether dogs could help tackle this problem in the marine environment. It began as a proof-of-concept project and has exceeded every expectation I had."
