Fishing authorities in Tasmania are to use DNA technology in a bid to clamp down on poaching and the catching of undersized fish. The technology has been developed through a joint project between the Tasmanian Aquaculture & Fisheries Institute and CSIRO. Nick Elliot, senior research scientist at CSIRO, explained that by using DNA it is possible to identify different species of abalone and even their places of origin, making it easier to police poachers.
