Schooling

Salmonid fishes will aggregate into schools when migrating and when holding in deeper areas such as pools in streams.

Coho Salmon spawning migration
A male Coho Salmon (Oncorhynchus kisutch) begins to asert himself by using the gaping threat while schooled in a deep pool during the last stages of maturation in the Autumn in an Alaska, USA stream.
