Salmon Habitat and Invertebrate Roles

The video discusses the 'Salmon in the Classroom' program, which uses salmon biology as an educational tool. Children observe the salmon life cycle from eggs to fry and release them into the river. The program emphasizes the importance of high water quality and diverse invertebrate populations for a healthy river ecosystem. The video also highlights the salmon's reliance on invertebrates for feeding in their natural habitat.
