The AUF's vision for spearfishing is "Safe, Sustainable, Selective, Spearfishing". Spearfishing with scuba gear is widespread among recreational divers. Backpacking, camping, day hiking, scuba diving, and spearfishing are among the activities available to visitors. Bountiful reefs around Marathon make it a popular diving, snorkeling, spearfishing, and lobster tickling area. Recreational fishing techniques include hand gathering, spearfishing, netting, angling and trapping. In Mexico a regular fishing permit allows spearfishing, but not electro-mechanical spearguns. Australia allows only recreational spearfishing and generally only breath-hold free diving. Fishing techniques include hand gathering, spearfishing, netting, angling and trapping. Memory Rock is home to great spearfishing and yellowtail snapper fishing. Fishing techniques include hand-gathering, spearfishing, netting, angling and trapping. Spearfishing in this manner has some similarities to bowfishing. Other developments in single-backed wetsuits include the suits designed for free-diving and spearfishing. Sand sharks are generally not aggressive, but harass divers who are spearfishing. A common way of catching this flounder is by spearfishing or jigging.
