The roach is one of the most popular freshwater fishing quarries in Europe. This species has an upturned mouth, much like the rudd (opposite), that enables it at times to take food from the surface of the water.
The roach inhabits mainly slow-moving rivers, canals, and well-vegetated still waters. Known for its ability to thrive in muddy or poor-quality water, the roach can also thrive in brackish inshore conditions, migrating up rivers from the sea in order to breed. It feeds primarily on insects, crustaceans molluscs, and plants – adult roach seem to prefer the latter.
The roach dislikes bright light and is most easily caught in cloudy conditions. It spawns among vegetation, from late spring through to summer. This species often interbreeds
with the common bream (below) and rudd (opposite). The roach multiplies fast and, where introduced, may become a pest. This shy fish can be caught using a variety of bait-fishing methods.
