✍️ Sample Spearfishing Questions & Answers
1. At what time of day are many reef fish typically most active and vulnerable to spearfishing?
Dawn and dusk are crepuscular feeding periods when reef fish transition between rest and active hunting, making them concentrated near feeding areas and less wary of divers.
2. What is the function of a wishbone on a speargun band?
The wishbone connects the rubber band to the spear shaft's notch so it can be loaded.
3. Why do many spearfishers practice the 'aspetto' or wait-on-the-bottom technique?
Lying motionless on the bottom draws inquisitive fish close enough to shoot.
4. What is the primary purpose of chumming (berleying) when blue water spearfishing?
Chumming disperses fish parts and blood into the current, creating an olfactory trail that draws pelagic predators up to the surface where divers can engage them.
5. What is shallow water blackout caused by?
Falling oxygen during ascent can cause sudden blackout without warning.
6. What is the primary cause of death among spearfishers during breath-hold diving?
Shallow water blackout, caused by hypoxia during ascent after hyperventilation, is the leading cause of death among breath-hold spearfishers.
