An acoustics survey has been performed at Genova (Italy) Aquarium aiming at characterizing the acoustic environment of tropical underwater habitats. Mid-term (5-7 days) measurements in tank containing tropical habitats have been chosen for a preliminary analysis. Spectral analyzes and eco-acoustic indices have been applied to derive information on the marine population activity and other sources. The measurements are strongly influenced by the presence of background noise, especially due to the technological systems dedicated to the operation of the aquarium which could not be completely silenced. However, the use of different indicators allowed to describe an artificial environment characterized by a strong anthropic influence and highlighted the ability of some indicators to bring out the presence of biological activity. Such approach will be used to compare environments with different degree of disturbance and derive information on the environmental quality of both artificial and natural habitats.

Abstract
An acoustics survey has been performed at Genova (Italy) Aquarium aiming at characterizing the acoustic environment of tropical underwater habitats. Mid-term (5-7 days) measurements in tank containing tropical habitats have been chosen for a preliminary analysis. Spectral analyzes and eco-acoustic indices have been applied to derive information on the marine population activity and other sources. The measurements are strongly influenced by the presence of background noise, especially due to the technological systems dedicated to the operation of the aquarium which could not be completely silenced. However, the use of different indicators allowed to describe an artificial environment characterized by a strong anthropic influence and highlighted the ability of some indicators to bring out the presence of biological activity. Such approach will be used to compare environments with different degree of disturbance and derive information on the environmental quality of both artificial and natural habitats.
