Ladyton, St Kessog’s and Haldane primaries were taking part in the Clyde in the Classroom initiative — which encourages children to engage with nature and protect their local environment.

Ninety-six schools took part in the project that sees children look after brown trouts by looking after their eggs before releasing them into the wild.

With the help of Clyde River Foundation scientists, pupils are responsible for the day-to-day care in a custom-made classroom hatchery over the course of three months.

Clyde in the Classroom started in 2000, as a one-off project for five schools in Glasgow. This year, 102 classes from 96 schools are participated in the program, totalling 2744 pupils.
