Lindsay Marshall is doing her PhD through the University of Tasmania and CSIRO Marine Research, Hobart.

In recent years, there has been an increase in illegal shark fishing across northern Australia, mainly by foreign fishing vessels. Vessels are regularly intercepted and catches confiscated. These often include dried shark fins. Identification of the shark species from which the fins were taken is crucial to risk assessment and exploitation rate estimates for north Australian sharks.

Lindsay’s work aims to examine the morphology of shark fins (denticle shape, fin size and shape, fin colour) as a tool to identify the species from which confiscated fins were removed.

She visited the Australian Museum on 12 April 2006 to photograph specimens and parts of Basking Sharks and Whale Sharks held in the Australian Museum Fish Collection.
