2.4 Appropriate disposal of shells and viscera
[*]Abalone may only be shucked when the vessel returns to land.
[*]Under no circumstances should shells or viscera be dumped in the sea. This is especially important if the abalone are moved to another area when landed.
[*]Take abalone catch home and dispose of the waste with household rubbish.
[*]
Under no circumstances should abalone viscera be used as fishing bait.My uncle used to lay cray pots a lot outside the heads (back in the day when you could legally use cray pots recreationally) and used coota as bait - though he was laying them one day, then returning for them the next.
