EUROPEAN RUDD

By Pennsylvania Sea Grant and Scardinius Erythrophthalmus

Abstract

The European rudd is a medium-sized fish belonging to the carp and minnow family. It is largely carnivorous when young, feeding on snails, insects, small crustaceans, and even smaller fish; but tends to prefer aquatic vegetation as it gets older.
