Dr. Tomonari Akamatsu from National Research Institute of Fisheries Engineering, Fisheries Research Agency, paid a visit to Baiji dolphinarium, Institute of Hydrobiology, Chinese Academy of Sciences (IHB) on Feb. 25, 2016. During his visit, he gave an academic report with the title of “Acoustic remote sensing of aquatic animals” for IHB researchers and students.   

“Passive acoustic monitoring of marine organisms has been getting popular in these years,” Dr. Akamatsu said in his lecture, “a lot of soniferous species were found and the acoustic characteristics of their vocalizations have been documented.” He afterwards played to the audience the sounds of some marine creatures. Based on these sound archives, passive acoustic monitoring network can be used as “an acoustic remote sensing” system to visualize the presence, location, species and even movement of target animals. Then Dr. Akamatsu introduced an acoustic remote sensing system, which was built on Japanese seismic monitoring network. “Location and time dependent acoustic presences of shrimp, fish and odontocetes can be visualized on a map in this way, time series of these maps provide a movie image of the distribution of aquatic animals, which was meaningful for marine biological resources management and marine wildlife conservation,” Researcher Tomonari Akamatsu summarized.   

Tomonari Akamatsu is an international renowned expert in marine mammal acoustics, who has established cooperative relationship with IHB since 1996 in acoustic research on Baiji and Yangtze finless porpoise.
