Measuring, Marking and Sexing Rock Lobster

​​​​​​​​​​

​Measuring rock lobster

The length of the rock lobster's​ carapace (shell) is used to measure its size. To measure a rock lobster:
  • Spread the antennal horns.
  • Place the gauge tip hard into the middle notch.
  • Measure from the notch to the end of the carapace.
If you are taking rock lobster close to minimum size, be sure your measuring device is accurate.




Tail-clipping rock lobster

​Rock lobster that you keep must be marked as 'recreationally-caught' fish as follows:
  • Cut off at least a quarter of the central tail flap OR punch a 10 mm hole in it.
  • If fishing from a boat, mark the tail fan within 5 minutes of the lobster being brought to the boat and before landing; or
  • If fishing from the shore, mark the tail fan within 5 minutes of landing and within 50 metres of the place where you are fishing.


Sexing rock lobster
