| In order to evaluate the effect of noise on some of growth factors and survival rate of Acipensernudiventrisfry a 40-day experiment was done through a completely randomized design framework with three repetitions.Ninety fish fry with the initial average weight and length of 18.7 g and 14.9 cm were considered.Thirty fish was considered as control and held in the voice intensity of 60 dB and the two other treatments were holdin the voice intensity of 80 and 100 dB. The Fish fry were tested in nine 45 × 40 × 70cm glass aquariums filled with water. The biometry of the fish was performed every 10 days and the weight, length, specific growth and survival factors were evaluated. ANOVA and Danken test indicated a significant difference between the mean weight, length, specific growth and survival rate in the end of the study. The control group mean total length was18.73±0.27 that was higher than two other groups (15.90±0.05 and 15.31±0.01 respectively. The Condition factor, which was the lowest for the control group, also showed statistically significant difference (P< 0.05). |
