This spring, pupils at Hemyock Primary School have been sharing their classroom with some unusually fishy companions. In early February, the pupils became proud custodians of 100 fertilised salmon eggs as part of a project the Trust runs called ‘Salmon in the Classroom’.
The school was given the eggs to look after with the help of Fred Leach, a local volunteer from the River Exe and Tributaries Association. The children were able to watch the amazing process of the eggs hatching into alevins and growing into tiny fry. A group of children from the school then released the fry back into their local river, the Culm. The released fry will help boost the wild salmon population in the river, as part of conservation efforts to prevent further decline of Atlantic salmon populations in the UK.
While visiting the release site, the children also had some close encounters with the bugs and beasties that live in the river. A sample was taken to identify which aquatic invertebrates were living in the river water. The assemblage of invertebrates found gives an indication of water quality, as some species can only survive if pollution levels are low. There were some unusual species in the sample taken on the Culm, including stoneflies, indicating that water quality in the river is good.
Salmon in the Classroom is part of a larger EU funded project, the WATER project (Wetted Land: the Assessment, Techniques and Economics of Restoration). This is a European land management project involving organisations in both the UK and France, investigating the improvements that can be made to water quality through catchment restoration and payment for ecosystem services schemes. The Westcountry Rivers Trust is the lead partner in this project and has been working with local farmers and landowners to carry out restoration work in the River Exe catchment over the past three years.
Good water quality means a healthy river ecosystem and salmon require a healthy river ecosystem in which to spawn and lay their eggs. The pupils of Hemyock Primary School are hopeful that the fry they have reared and released will one day make it back to the Culm to breed, ensuring that our most iconic species of fish, the Atlantic salmon, has a future in the rivers of the Westcountry.
