Even though this term might make you think of ocean fishing, deep sea fishing refers to that which is performed in waters as large as or larger than lakes. Rivers and ponds are not meant for deep sea fishing as the water may not be deep enough. Generally speaking this type of fishing is carried out near coasts where there are a lot of large fish.

Deep sea fishing requires large vessels for the operation 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 resist strong winds and bad weather at sea and to facilitate the access in the fishing area fast 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 types of fish species captured at the same time with these large ones; however, the latter are not the real intended game. Such fish represent by-catch or even bait for other larger fish.

Deep sea fishing became a basic occupation in coastal areas, allowing people to earn their living, and later it became one profitable kind of business. It is done in California, Florida, north of New Zealand, in Nova Scotia, Hawaii and so on. One of the advantages of those areas is that large fish live close to the coasts and it does not take a long time to get to these places.

Deep sea fishing involves several techniques out of which the first to mention is trolling, that is a form of angling performed by drawing a baited line on the bottom of the ocean. The bait usually resembles squid or other smaller fish regularly used for bait and it is used behind the boat. Deep sea fishing boats have an equipment called stabilizers or outriggers that make the fish catching area larger. Another technique is the chumming or chunking which requires that large pieces of bait fish get thrown overboard in order to attract the larger wanted species.

All in all, deep sea fishing has developed proportionally because people's demand for large fish in their kitchen. Presently, diet variations with fish dishes have actually become an epitome of healthy living, and many people give up red meat for this white lighter variety.
