Fishing reefs up north we get a wide variety of small "bycatch" species, as well as undersized "targets" like coral trout and red emperor. Many are "blown", and few can "self-vent" (red emperor are notable for this ability).

The NT Fisheries has posted a video showing hollow-gutted, feeble, golden snapper (in a cage) on the seabed after venting at the surface using a hollow needle. Their policy discourages catch and release of golden snap
