Aim of this study was to evaluate the effects of diazinon toxicity (LC₅₀) on silver carp and roach fry for measuring resistnce of these fishes. Roach with an average weight of 7 ± 1 g and silver carp 30 ± 1 g were studied to measuring lethal concentration LC₅₀ at 96 hours. Experiment was used with a completely randomized design in 9 treatments and 3 replications for both silver carp and roach. The results showed LC₅₀in silver carp 3.93 (2. 94-4. 99) mg/l was more than roach 1.71 (1.20-2.23) mg/l that means higher diazinon resistance of silver carp than roach.
