Bottom hunt Spearfishing Techniques
How To Hunt with waiting at depth
Bottom hunt spearfishing techniques with waiting for the prey at certain depth requires a great physical condition of a hunter. This spearfishing technique usually aims at hunting bigger predator or pelagic fish.
The bottom hunt technique of waiting at depth is conducted with dives deeper than 10 m, which usually makes apnea a little longer.
Depending on the psycho-physical condition of the hunter and the depth at which the fish is hunted, the average length of these dives last from 1 to 2 minutes.
With repeated dives, the length of surface time should be at least 3 times longer than the length of dive itself.
The best time for bottom hunt usually proves best fruitful in the early morning hours, but results should be satisfactory during the whole day.
Sea currents caused by tide greatly influence the feeding habits of the fish. During the hunt, it is best to use those sea currents that bring nutrient substances and organisms.
These increase the food chain activities, the peak of which are bigger predator fish.
The choice of a suitable terrain for bottom hunt spearfishing technique. The most appropriate are steep shores, straits or channels, and exposed shallow banks and reefs. On these areas the marine life gets very intensive while the terrain offers the hunter great places for cover while praying for the fish.
Predator fish are habituated around or in the vicinity of such terrains and pelagic fish frequently visit them on their ways.
The key to success for every hunter therefore lies in the familiarity with these locations and understanding of the basic factors that influence the marine life (winds and currents).
All these factors dictate the behaviour of the predator fish. Underwater hunter with experience should have no troubles with the right choice of the hunting location when employing the bottom hunt spearfishing technique.
When conducting this diving technique, we can count on curiosity of the predator fish. Pelagic species are usually less timid. Therefore the first part of the diving technique is no different than the usual apnea dive.
In the second part the diver should not perform any fast or unnecessary movements while drifting into the depth. The last part of the dive should be carried out with practically no excess movement due to the negative buoyancy of the hunter.
The speed of sliding is controlled by halting with the fins untill the desired depth is reached. The hunter should pick the most appropriate position on the seabed a few meters beforehand and it should provide him some cover as well.
When the desired depth is reached, he should keep perfectly still. Bottom hunt spearfishing technique will entice curiosity with predator fish which will lure them closer to the hunter.
The general rule for the position of the hunter is the following: when hunting pelagic fish, the hunter positions himself on more exposed spots on the seabed (bigger rocks, ridge edges...)
It may happen that the hunter notices hesitation of the fish. On such occasion he should give the impression that he fears the fish, e.g. slowly and calmly retreating back to his cover.
Such behaviour will only encourage the fish. Some other species of predator fish are, on the contrary, disturbed by exposed position of the hunter and will therefore keep away.
In such cases the hunter is to choose more camouflaged spots, such as crevaces, voids or positions 2 or 3 m away from the edge of the ridge.
Exploiting the direction of the sunlight and the choice of positions for the bottom hunt spearfishing technique is therefore focused on the shaded areas.
This is of key importance. It is awell known fact that predator fish have a very sharp vision and are therefore more sensitive to daylight. The hunter should choose his position in the shaded areas of seabed, with sunrays coming from behind.
With exposed seabed areas, tide or intensive sea currents, underwater hunting with the bottom hunt spearfishing technique will at least be interesting, if not very fruitful.
Experiences of underwater hunters have shown that the average waiting (bottom) time to notice the fish is 30 seconds. If the fish is not seen within this time, then waiting is no longer sensible.
There are 4 key stages of an average dive at spearfishing with bottom hunt spearfishing technique. Each of them lasts about 30 seconds:
1. Conducting a calm dive to the depth (approx. 20 metres)
2. Bottom time should not exceed 30 seconds
3. Potentially getting close to a fish and waiting for a shot. Each hunter is to make his own judgement as to how long he will persevere at stage 3
4. The last stage of the dive that must not be neglected is the time needed for the return to the surface. Underwater hunter should lay all his attention and concentration in performance of the dive with this spearfishing technique.
Why lure the fish? It may happen that while waiting the hunter notices hesitation or excitement of the fish.
At such moment he may well use some of the luring techniques. By these, the fish become curious and start approaching.
Usually we employ different gargling sounds from the throat or mouth. The hunter is not to move at that time. That precise 'something' that successfully lures the fish, however, is usually kept a well hidden secret by the experienced hunters.
Being highly demanding, spearfisghing technique of waiting at depth demands the choice of professional equipment.
When it comes to purchasing diving equipment, saving is not a safe bet. Second hand or damaged wetsuit will increase the loss of body heat and by doing so increase the use of oxygen at each dive.
This fact needs to be taken into account as on it depends the length of apnea of the underwater hunter, as well as his safety. We should add to this point the importance of carefully selected swim fins, as their quality, hardness and material strongly influence displacement. This has an important role when ascending back to the surface.
Length of the speargun is usually somewhat greater for this technique of spearfishing with waiting at depth. 110cm in length or even longer, the spearguns can also be heavier or robust, enabling the use of a thicker harpoon, which in return increases the penetration.
Manoeuvrability of the speargun does not play the key role with this technique of spearfishing.
Important spearfishing tips:
1. The spearfishing technique of waiting at depth should always be conducted in the vicinity of a boat, from which someone carefully monitors our diving and times the length of apnea. If there are no strong currents, there is no need to anchor the boat as the proximity of the boat will be of no disturbance to the fish at depth.
2. The choice of depth at which your hunt is to be carried out should be adjusted to your psycho-physical abilities and current condition and level of fitness. Diving reflex can be very different!
3. When the sea cools down, the safety factor for the length of the dive should be adequately increased.
