An experiment of sound effects on shrimps for ecoacoustics' research

It is important to understand relationships of underwater soundscapes, marine ecology, and acoustic behaviors for refine research questions on ecoacoustics. Benthic crustaceans live in a local range and are normally used to an indication of environmental impacts, especially for the ecosystem in ocean. To get much information of interaction impacts on benthic crustaceans, this paper introduces an experiment of sound effects on shrimps in an aquatic pond. In the experiment, there is only a kind of benthic crustaceans, Penaeus prawns. Environmental and artificial noises are recorded by a passive sound monitor. The preliminary results are obtained through preprocessing data acquisition, analyzing effective phenomena, and comparing sound characteristics. It will be valuable to consider much simple cases for main questions. So data of natural rainfall noise, aerator noise and artificial noise may help to know about the acoustic ecology of shrimps in an aquaculture environment. Since the water quality is very poor in real shrimp pond, it cannot accurately obtain the relationship between the sound of shrimp and its behavioral characteristics. Further research considerations are also be prospected in this paper. [The project is funded by The National Natural Science Foundation of China (41374147) and (14111103900).]
