Özet

Zebra mussels are a preferred prey for most crayfish but this tendency of consumption has not been tested in lab and field experiments especially in Turkey. For this reason, 18 juvenile crayfish (Astacus leptodactylus) and 240 juvenile zebra mussels (Dreissena polymorpha) of 1.95 mm in mean length were used in the experiments. At the end of the second day, faeces of the crayfish were examined in all petri dishes, and a large proportion of the granular fish feed had not been consumed by the crayfish. These results show that crayfish were potentially significant predators and may be able to limit zebra mussel populations
