We Quote Terence I. Walker (2010) "Population biology and dynamics of the gummy shark (Mustelus antarcticus) harvested off Southern Australia"

There is now high confidence in the stock assessments of M. antarcticus and the fishery is now one of Australia’s most securely managed fisheries. Furthermore, the present study demonstrates that the effects of sampling and, more importantly, of intense fishing using length-selective gear produce various biases in the data and parameter estimation that are likely to occur in many other fisheries. The study also demonstrates that a shark species of medium biological productivity can be harvested sustainably, whereas earlier there were doubts about whether any shark species could be sustainably harvestable.
