Although the terminology “deep sea fishing” seems to refer to marine fishing trips, the term actually applies to any type of fishing in waters wider than a lake. Rivers and ponds can not mean “deep sea fishing” as the water is too shallow in most cases. Open sea fishing is carried out outside coastal waters that is the habitat of lots of the larger fish.
Deep sea fishing requires bigger boats for the task so as to maneuver and store the catch conveniently. Such a boat should have enough room for the crew meant to carry out the fishing and also for the equipment needed in order to catch and store the big fish. It should be the type of boat intended to withstand storms and bad weather at sea and to facilitate access to the fishing area quickly and safely.
The wide range of fish that are caught in deep sea fishing includes marlins, swordfish, sailfish, large tunas and various types of sharks. There are also smaller species of fish captured at the same time with these large ones. However, the former are not part of the plan. These come as by-catch or, if caught intentionally, they are meant to be turned into bait for the larger fishes.
Open sea fishing became a basic occupation in coastal areas, allowing people to earn their living. Later it became a proper business. California, Nova Scotia, Hawaii, Florida, New Zealand are among the most common locations. A big advantage of those areas is that the possibility of catching big fish along the coasts is triple that of other regions where the various large species live in far deeper waters.
Deep sea fishing involves several techniques out of which the most common is trolling, that is a form of angling performed by drawing a baited line on the bottom of the ocean. The bait usually is squid or other smaller fish caught for baiting purposes and it is cast behind the boat. The stabilizers behind the boat also called outriggers work great in spreading and enlarging the area for catching the fish. Another technique is the chumming or chunking which requires that large pieces of bait fish get thrown overboard in order to attract the desired larger species.
It is easy to understand that open sea fishing has been developed commensurately with larger market consumption. Nowadays, more and more people in large cities are beginning to be able to afford to vary their diets to include various sea foods, big deep sea fish have become more popular than ever.
