Pupils learn about trout’s life cycle Levin North School trout breeding project is about to end. Within the next few weeks a decision will be made on where to release the trout. Of the 100 eggs approximately 40-50 have survived and grown into fish of different sizes. The children have thoroughly enjoyed looking after the trout and learning about their life cycle. The senior class is currently studying water quality and once that project is completed a decision will be made about releasing the trout. Dan Brizzle, a past present of the Horowhenua Freshwater Anglers Club, said the whole school had enjoyed the project and was keen to do another trout hatching project next year. He had been trying for some time to find a local school prepared to take it on and was delighted when Levin North School said yes earlier this year. The trout have been the subject of several classes and study projects at the school. The children wrote about the trout’s life cycle and made drawings of it.

Aiden’s view When the trout life cycle starts it starts at eggs. Then the eggs hatch and turn into alevin. When the alevin ‘button up’, going to the top to find food, they turn into fry. After the fry it turns into fingerlings. When the fingerlings get bigger they turn into juveniles and they are just about adults. When the juvenile gets bigger it turns into an adult. Then the

trout life cycle starts all over again. Aiden

so they can get food. Then they turn into fingerlings. They get bigger and bigger. Kendall
