Today we went on a trip to Ardnacrusha and Parteen Weir. I’m going to tell you about some of the things I learned.
First we went to Parteen Weir, a fish hatchery. We learned about the life cycles of the Irish salmon and the European eel. We went to see all the male salmon in the tank. Tom caught a male salmon with a net. I didn’t really want to touch him because he didn’t look too appealing.
We went to see the female salmon. They were slightly smaller and had a different pattern. To get the eggs out, you have to put your hand around her gills and squeeze.
We then saw the babies, called the fry. We learned that they get microtagged and get a fin cut off so the people at Parteen Weir know that it’s one of their fish. We saw the men doing this. First they put them in a tub of anaesthetic so the fish don’t feel the operation.
We then got the bus to Ardnacrusha, and we had our lunch in the visitors’ centre. We watched a video about hydro-energy. We got dressed in high-vis jackets and helmets, and we climbed a lot of steps and stairs. We went inside a big room at the top of the building where they control the water electricity with flicks and stuff. That was my favourite part. It was very cool.
