Meet the kids helping to bring back Scottish oysters

Oysters might only be tiny, but they're a key part of our oceans, helping to clean the water and providing shelter for sea life.

There used to be millions or even billions of native oysters in Scotland, but their numbers have fallen to very low levels due to problems like overfishing and disease.

In Ullapool, a project is taking place to help grow and reintroduce Scottish oysters back into the lochs and seas they used to call home.

Callum and Jamie, who are part of a local kids' environmental group, headed out on a boat trip to see the work that the community is doing for these little creatures.
