The Belize Fisheries Department has legislated a ban in spear fishing
The new statutory instrument states that: – No person shall engage or attempt to engage, or assist a person to engage in spearfishing, of any kind, within a Marine Reserve. – A person within any Marine Reserve who possesses any of the following equipment on board a vessel, or on his person will be presumed to be engaging in or to be attempting to engage in spearfishing; a) speargun, b) polespear, c) hand spear, d) Hawaiian Sling e) iki jime or kill spike f) any other elastic, pneumatic powered, or mechanically powered speargun or sling.
and also be aware if you just have one in your boat when your in any of the zones below or even stuffed up in the bow with no intention of using it they can impound your boat and arrest the captain and have a history of doing so.
If you need a definition of 'Marine Reserve' it includes Conservation Zone,Preservation Zone,General Use Zone, National Park and Recreation Zone.
