Study on the Acoustic Signal Characteristics of Feeding Activity of Penaeus Vannamei

To solve the problem of intelligent feeding of Penaeus Vannamei, this paper presents a study on the characteristics of acoustic signals during feeding, which can adaptively control the feeding amount. In this experiment, a sound acquisition system was designed for the weak sound signal of feeding of Penaeus Vannamei. The sound signals of different feeding states of Penaeus Vannamei were collected under the condition of artificial feeding through several feeding box experiments. Through a large number of data analysis, we get and confirm the typical sound signal of feeding of Penaeus Vannamei. The frequency band of sound signal distribution in feeding of Penaeus Vannamei was studied. It provides theoretical support for further study on the feeding pattern of Penaeus Vannamei.
