When to see

January to December


The perch is a medium-sized fish with a characteristic humped shape. A predator, the perch feeds on invertebrates, crayfish and other fish. It lives in large ponds, lakes, reservoirs, canals and lowland rivers, and is often seen in shoals. Spawning takes place in April; the females produce sticky bands of eggs which they wrap around vegetation and rocks, ready for the male to fertilise them. After about three weeks, the young hatch and feed on the yolk sac until it is finished.

What to look for

The perch is a greenish fish with dark, tiger stripes, a large, spiny dorsal fin, red pectoral and anal fins, and a red tail.
