Never tried this sport before but I do get a kick everytime I stick on a pair of goggles. Never seen the logic in some people thinking this or any other bloodsport is not giving the animal a fair go but that is another issue I suppose. As far as baglimits are adhered to and the bag limits are adjusted if there are issues then sustainable harvesting is cool.
Is all spearfishing done without scuba? Where are you generally allowed to spearfish ie can I spearfish in the GC Broadwater, the seaway or out on any of the GC reefs for instance?
