The hatchery and eggs have been in P4 for a couple of weeks and we now have some young fish, known as Alevin ( they still have the yolk sac attached to them to feed from). Louise, the scientist from the Clyde River Foundation, visits the school each week to oversee the trout development and is really pleased with how well the young fish are being cared for by the class.
The children have shown great commitment in caring for the fish. They have learned how each part of the tank works and what needs to be done to maintain a perfect environment for the fish. The water must be kept cool by using ice packs, in the form of frozen bottles. The children monitor the temperature of the tank by recording the temperature 3 times a day and keep the water clean by regularly replacing with fresher water.
Here are some pictures of the tank:
As the fish continue to develop, the children will be engaging in various learning activities. These activities will allow them to become more aware of how to look after their local environment and encourage a responsible attitude.
Some examples of their learning activities:
- The trout lifecycle
- Parts of a fish body
- Looking at the fish food web
- Understand the water cycle in relation to the River Clyde
- Investigate the effect humans can have on a river eco-system
Finally, when the yolk sac is used up the Alevin are known as Fry and need to feed themselves. At this point P4 will release the fish back into the environment. The plan is for P4 to release the fish into a local stream which then feeds back into the River Clyde.
