In this study, quantitative ground vibration values and damping coefficient produced by underwater blasting were measured and analyzed. Also, hydrospace noise in aquafarm and noise in atmosphere as well as ground vibrations were measured, and maximum values of these results were 86,8 dB(A), 147,8dB(A), 0.244 cm/s, respectively, With these results, vibration influence about snakehead (channa argus) and structures were examined. the damage of those was proved that is not. Equations of vibration ($V_{50%}=1.507SD^{-0.536},;V_{95%}=2,171SD^{-0.536}$) and hydrospace noise ($SL=293.2SD^{-0.164}$) were presented from quantitative experiment results. respectively. The results of the study may be applied for the evaluation of the influence on aquafarm as a basic data before having main underwater blasting at construction sites.
