Perch

Perch are coarse fish that have been introduced to Loch Rannoch and which are well defended with spines that are embedded in their dorsal fin. Nevertheless the pike in Loch Rannoch still eat them.

Perch are themselves predators and feed on smaller fish such as minnows. Perch breed after two years and have a lifespan of about seven years.
