Ms Rossvoll showed us how to feed the salmon. You take the lid off the tank.You take a pinch of food and sprinkle it on the water. The salmon swim up to the surface to catch the food. The food sinks to the bottom. We have now been given advice not to feed them. We think this is because they still have tiny yolk sacks.

During the holidays I have been checking the fish, I thought you might like to see how the salmon are progressing. Following Mr Paterson’s instructions I turned the temperature up to 6 degrees on Monday.
We are creating a model of the lifecycle of the salmon. We have made clay smolts as part of our understanding of atlantic salmon. We are making eggs, parr, alevin, smolts and fry out of different materials. The challenge is trying to make the different stages of the lifecycle to scale. We decided to make the smolts out of clay.

The salmon are being kept at 6.0 degrees and if the temperature goes up to 12 degrees they die. During the power failure there was no power in the aquarium so the temperature went up to 11.2 degrees because the cooler was off. It was 4.0 degrees when we first got the salmon eggs from the River Ythan Trust, when we moved it up to 5.0 degrees they changed to alevins faster because the temperature was higher.The temperature has gone up so they can grow faster.

When the aquarium arrived it took a week to get it up to temperature and the salmon eggs came from the West Coast from the Carron River. They were in a polystyrene box surround by ice with no water. After the weekend we were all excited about the salmon eggs. They are now alevins.
