Key Facts

  • Mud crabs are caught in recreational and commercial fisheries across northern Australia.
  • Caught in commercial fisheries in NT, QLD and NSW, there is no immediate cause for concern regarding stocks. However, the impact on the population of increasing catches in QLD and NSW is uncertain.
  • Stocks are protected as juvenile mud crabs must be returned to the water in order to reach breeding size.
  • Bycatch of undersized crabs is significant, but these are returned to the water to reach breeding size.
  • Crabs are caught in pots and traps, with minimal habitat disturbance.

Mud crabs are caught by recreational and commercial fisheries across northern Australia. While there is no immediate cause for concern around mud crab stocks, the impacts of increasing catches are unknown in both QLD and NSW. In QLD, stocks are partly protected because only male mud crabs are caught and females are returned to the water. Catches of mud crab in NT are relatively small compared to the abundance of the species in Territory waters. Juvenile mud crabs caught in all these fisheries must also be returned to the water in order to reach breeding size.

Mud crabs are mainly caught using crab pots and traps, which are lowered to the seafloor and remain in place until they are lifted up for harvest. Impacts on habitat are minimal.
