HARPOON is a long spear-like instrument used in fishing, whaling, sealing, and other marine hunting to catch large fish or marine mammals such as whales.
It accomplishes this task by impaling the target animal and securing it with barb or toggling claws, allowing the fishermen to use a rope or chain attached to the butt of the projectile to catch the animal. A harpoon can also be used as a weapon.
HARPOONING HARPOON
What do harpoons catch ? Fishermen use harpoons to catch very large fish, like swordfish or bluefin tuna , at certain times of the year when these fish are found swimming in surface waters.
Accessory Equipment Harpoons differ from spears in that the point becomes separated from the shaft when it penetrates the victim and the shaft floats to the surface. The point and the shaft remaining connected by a line.
Whaling harpoons have a retrieving line which runs from the shaft of the harpoon to the operating vessel. The line, with a total lengths of up to 1 000 m is running through a tension absorber, from there it is led round the drum of the whale winch then down to the hold of the vessel .
Handling Equipment Modern harpoons can be pushed or thrown by hand as well as they can be shot with rifles or guns. Harpoons are a very common fishing gear for sport divers. Commercial fishing activities with harpoons are of minor importance .
Fish Operation When a prey is sighted, the vessel is steered towards its position, and the striker positions himself on the stand with the harpoon made ready directing the helmsman so that he can make his strike and capture the target species.
