We had a visit yesterday from Willie, our visiting scientist for Clyde in the Classroom. He checked our hatchery and was really impressed with how well our fish are being looked after! Out of 200 eggs that were given to us we have around 193 that have hatched and are now classed as alevins. We have been learning about the life cycle of the brown trout and are now waiting until they develop and grow before they can be released into a local river.

Have a look at the video of our alevins, you should notice that they huddle together around the pebbles to hide. This is because in the wild they are in reds under the stones and don’t like light. Willie told us that the scientific term for this is negatively phototactic.
