The Sanday mini-hatchery

Here’s a short video filmed by the pupils showing a typical routine check of our mini brown trout hatchery: water temperature reading, removal of dead ova, solar pump check, water level, etc…
The mini hatchery is located outside and submitted to the changing weather conditions as opposed to the Stronsay set-up,located in a shed at a more constant temperature. This explains why, the Stronsay ova have all hatched by now whereas they haven’t started yet on Sanday.
