Description

How did a DFO scientist end up on Robinson Crusoe Island?

Acoustic surveys performed by Fisheries and Oceans Canada use echosounders to detect and enumerate fish using sound, in tandem with capture nets to identify the species and collect information on the size of fish. The DFO science program is working on the development of alternative and noninvasive methods to gather this information, for example by deploying underwater cameras where the use of trawls is not possible. Dr. Stéphane Gauthier, Ocean Sciences Division was contacted by colleagues in Chile to test such an alternative approach on a remote island off the central coast of Chile sponsored by the United Nations Office for Project Services (UNOPS). Robinson Crusoe Island is home to a small secluded fishing community and hosts a rich aquatic fauna unique to the Juan Fernandez ridge ecosystem. His team designed an acoustic survey around this island and used echosounders deployed off a small vessel as well as a Remotely Operated Vehicle (ROV) equipped with cameras systems. The project was highly successful, revealing a rich and diversified reef ecosystem.
