Rudd

• Ruds are schooling fish that live mainly in stagnant, densely vegetated waters.
• Since the rudd also reproduces with other fish species, genetically pure rudd has become very rare.
• The fish can track approaching predatory fish via their sideline as they feel slight movements. However, they can ignore this "warning system" in heavy swell, which makes it easy for predators to catch them.

Rudd and roach are very similar and therefore difficult to distinguish. However, you can separate them from one another by their mouths: The rudd has a mouth that stands higher up. They can also be distinguished by the red eye of the roach that gives it its name, as the rudd has a more yellow-gold eye.
