The trade in shark liver oil is an invisible threat to sharks. Not only is there limited research on the topic, but liver oil is notoriously difficult to track and trace. Enter Dr Madeline Green, molecular fisheries ecologist and Principle Investigator of the Forensic Fisheries Lab at the University of Tasmania. Madi is working to apply protocols from the tracing of olive oil to extract DNA from shark liver oil samples, in order to identify species and help monitor this complex trade. In this episode, we learn all about Madi's research, and how the trade in liver oil is presenting a significant threat to deep-water sharks.
