Deep sea fishing, often referred to as open water or off shore fishing, is a form of the sport that involves going offshore. Typically, this type of fishing occurs in large saltwater oceans and requires fishing from a boat. Boats can range from small vessels up to extremely large engine-powered fishing boats. Deep sea fishing is much more dangerous than offshore fishing, mainly because of the risks involved with being out on the ocean and unpredictable weather patterns. The types of fish in these waters are usually much larger and much more unusual than smaller fish that are found near the shoreline. Some common sought after fish in deep water include marlin, tuna, sharks, and swordfish. Special rods and reels must be used for deep sea fishing, since they have certain weight requirements. The rods must be made of strong carbon material in order to support the weight of the fish, and the line is a thicker material as well. Not everyone who enjoys deep sea fishing owns their own boat. In fact, most fishermen who enjoy this type of fishing will charter a boat for individual trips.

There are usually deep sea fishing reports that can be found on local radio stations or online that will alert fishermen to the current conditions. It tells people where the best catches can be found. These reports will also include a weather update, since certain weather conditions can prevent boats from going out on the ocean. Windy and rainy conditions are not recommended for deep sea fishing excursions. Most of the thrill of this form of fishing is trying to get the largest and heaviest fish possible. Often, people take pictures of their catch and share them with other fishermen around the world. Many people make it a point to charter a boat while on vacation in places like Florida or the Bahamas. Not all fish caught out in the deep ocean are for eating; many catches are displayed on peoples' walls as trophies. Deep sea fishing is an extremely fun and exciting sport that can bring in hundreds of pounds of fish in one trip. Many deep sea fishermen do it for a living, and can be out to sea for months at a time. No matter what your level of expertise, this is a great sport that offers a lot of fun and a thrilling experience for everyone involved.
