Description: 
Sharks were caught by rod-and-line and a small tissue sample taken before they were released at the site of capture. DNA will be extracted from the tissue samples to allow us to compare the WA population with those in the Northern Territory (Daly River, Van Diemen Gulf) and Queensland (Wenlock River).
