Influence of Eyestalk ablation and temperature on molting and mortality of narrow-clawed crayfish (Astacus leptodactylus)

In this study, two experiments were conducted to investigate the effects of eyestalk ablation and temperature on molting and mortality of narrow-clawed crayfish (Astacus leptodactylus) in three replicates. In experiment 1, the percentage of molting in ablated crayfish was significantly higher than the percentage of non-ablated crayfish in control group (P<0.05). In experiment 2, the highest molting and mortality rate was found at 32°C in ablated crayfish treated with four different levels of temperature (20, 24, 28 and 32°C). At temperature of 20°C, the animals had low mortality as well as reduced molting rate (P<0.05). Mortality was mostly occurred within the first days of the trial. Proficient and proper nourishment was found to be very important in all treatments in this study.
