There are two other less obvious spines, one on each gill cover, which quickly become known to the unwary angler who handles his catch carelessly!
The pelvic and anal fins, and the lower half of the tail are orange red in colour. The olive green back is tiger striped by six or seven dark bands which extend down to a silver/white belly.
Perch like still water and often frequent the shallows, especially where there are underwater structures or snags such as tree roots or jetty piers. Smaller perch swim in small schools, larger fish are usually solitary.
Perch are easy to catch, though they are not caught during the hours of darkness, and will take natural baits and spinbaits with great vigour. They are particularly attracted to the colour red.
Perch are usually very numerous wherever they are found and consequently the size of the fish are small. Large perch are sometimes caught weighing up to 2.2 kg.
