Abstract：The fish analysis is the main direction of biological monitoring of water quality at present.Aiming at the problems such as weak strength of the fish bioelectric signal, easy to be interfered by noise, and lack of effective determination basis of fish water quality monitoring sensor.Filtered and increased the fish bioelectric signal collected by the observation electrode.Then through MCU MSP430 to collect and convert the signal, while in the upper computer based on Labview program, the power spectral density of various active potential signals (breathing and swimming movement) of the fish were calculated respectively to realize the frequency domain analysis of the bioelectrical signals of the fish.Then, combining with the new criterion of whether the variation of various movement power proportions exceeds the threshold value, the early warning judgment was completed.Finally,the effectiveness of the system had been proved by experiments.
