Julian Hughes is a Senior Research Scientist in the Fisheries Resource Assessment unit based at the Sydney Institute of Marine Science. He currently manages the biological monitoring component of the Recreational Fisheries Monitoring Program (RFMP). The RFMP is a comprehensive citizen science program that engages with thousands of recreational fishers who voluntarily provide information on their fishing activities within a rigorous survey framework. The aim is to deliver high quality, up-to-date information on recreational and charter fishing in NSW. Information collected by the RFMP contributes to the ongoing sustainable management of NSW’s shared fisheries.  As a member of the Fisheries Resource Assessment unit, Julian is also responsible for carrying out the regular stock assessment of several economically important fish species, including yellowtail kingfish and mulloway. Julian's other research interests include the effects of barotrauma on fish, connectivity and population structure of fish stocks, fisheries biology, trophic ecology and survey design. Julian supervises a number of post-graduate students.

Julian joined the Department in 2003. He completed a Ph.D. – "The Biology and Population Structure of Eastern Australian Salmon (Arripis trutta) in South-eastern Australia" at the University of NSW in 2012.
