Abstract
Since 1962 anti-shark measures have considerably reduced the incidence of shark attack in Queensland. The measures include the use of baited lines as well as nets, despite earlier criticism that baits may attract sharks to regions which they otherwise would not frequent. Evidence from Queensland indicates that similar criticism could apply to the use of nets as sharks have been caught when attacking previously meshed target and non-target species. Catches of whaler and hammerhead sharks, Carcharhinus and Sphyrna spp. respectively, have declined, those of tiger sharks Galeocerdo cuvieri have increased while those of white pointer sharks Carcharadon carcharias have not altered. Catches of non-target species, some of which are otherwise legally protected in Queensland, are not as high as those reported in some commercial fisheries but are significant in the context of a long-term programme which is highly valued by the public.
