Blue Water Spearfishing
How To Hunt In A Blue Water
Blue water spearfishing originates from Polynesia and is considered the oldest technique of spear fishing techniques. This technique is mostly conducted in crystal clear water.
The hunter selects the target i.e. a fish swimming at certain depth from the water surface. The selected prey should be positioned as vertically as possible to the position of the hunter above.
In such position the fish has the lowest perception (by its flank) of the vibrations, caused by the hunter.
With the blue water spearfishing technique, approaching the fish in the vertical direction and shooting the fish from above downwards are of key importance.
Nowadays the blue water spearfishing technique is most widely used in the regions of Oceania, Australia and other sparsely populated areas. In more densely populated areas with increased tourism, greater number of vessels and underwater hunters, however, the results of using such technique are not as good as they used to be.
The simple fact is that due to getting agitated more frequently, fish have become much more wary than they used to be.
The blue water spearfishing is considered a bit easier to conduct than the technique of waiting for the prey at a certain depth.
With this technique, there is namely no waiting at the depth for the fish to come close, hence the depths achieved are also greater.
The blue water spearfishing technique includes the following stages:
1. Swimming on the surface: swimming quietly and calmly without causing excess vibrations which could agitate the fish;
2. Observing and selecting the prey: swimming calmly to be able to observe the movements at the depth and focusing your attention onto the depth;
3. Conducting the dive: an optimum surface dive technique with the minimum of noise is of key importance. Jerky movement of arms, sudden bending at the waist and splashing fins on the surface are to be avoided.
4. Diving to the depth: for the first few metres the hunter has positive buoyancy and propels himself by means of fins. The hunter should be weighted in such a way that the neutral dive stage starts below the depth of 10 metres (and not before) when the hunter's buoyancy is equalised, the hunter thus sliding to the depth with no excess movement.
The diver is able to steer by leaning his head and upper part of the body. The next stage is that of negative buoyancy when the diving speed increases. To prevent this, the hunter should control his speed by spreading his legs and placing the fins transversely to the direction of movement.
5. The last stage of the blue water hunting involves getting close to the fish to bring it within range for a shot. Already before that, the hunter should take the position with the speargun and his arm stretched, aiming at the target. Hence no extra movement is required for getting ready to fire. Now the hunter only has to wait until the fish is within speargun range.
For the blue water hunting longer spearguns are used, usually with power bands, as greater range, precision and power of the speargun are the characteristics required. With this technique, the speargun manoeuvrability plays no key role.
The characteristics of other equipment for this spearfishing technique:
- due to reaching greater depths, the mask should be of very low volume.
- the fins should provide great propulsive power to enable effective ascent of the hunter from great depths to the surface (long blade fin).
- the wetsuit should be a smooth snug fit to prevent unnecessary noise while diving. The wetsuit thickness may considerably affect the weighting of the hunter, therefore the wetsuit material should be as thin as possible. Wetsuits made of soft and thicker neoprene are not suitable for this spearfishing technique.
- Determining the correct weighting of the hunter is closely related to the previous paragraph. Due to great depths achieved with this technique, such weighting should be the least possible. The weighting test can be performed by diving to the depth of 10-15 metres, where buoyancy is to be neutral floating in the blue.
Spearfishing tip: The blue water spearfishing requires a certain amount of experience. However, the moments of catching the sight of the fish immediately before the shot can bring a lot of adrenaline rush.
Yet such moments, on the other hand, require utmost concentration on the part of the hunter.
His attention should at all times be focused on the following:
- it is necessary to quickly evaluate the agitation of the fish and the distance to the fish so the spear can be fired before the fish escapes.
- the hunter should always be aware of the depth reached which should never go beyond his abilities.
