AB  - Effect of four different bait types (bread, potato, apple and prussian carp Carassius auratus gibelio (Bloch 1782) on efficiency of fyke-nets for catching crayfish Astacus leptodactylus Esch. 1823 were tested. Trapping was conducted in Lake E?irdir of Turkey. The results showed that catching efficiency of fyke-nets with bread, potato, prussian carp and apple were higher 20.3%, 11.2%, 7.4% and 7.1% than those without bait, respectively. But, the difference in catch between only with bread and empty fyke-nets was found statistically significant (P0.05). In addition, crayfish caught with prussian carp and empty fyke-nets tended to be larger (in total length) than those caught with bread, potato and apple. But, there was no significantly difference between groups (P0.05). The catching rate of males captured with potato was higher than with the other bait types and without bait. Differences between potato and the other groups were statistically significant (P<0.05).
