Big game fishing is a type of fly fishing that aims to catch fishes of huge proportions such as tunas and blue marlins. This kind of fly fishing hobby is more like a sport since the effort of actually catching a single fish requires strength and agility.

This type of game fishing is usually done near ports and temperate coasts. Since big fishes are their target, the usual spot for fishing are located in deep coastal areas. As the location pertains, the boat should be seaworthiness. This means that the boat should be sufficient enough to carry several pieces of a four to five-footer fish. Normally boats required should be trailer able eighteen-foot minimum to about a hundred feet to be able to transport fishes to and from the fishing grounds.

There are two bait techniques effective for big game fishing. First is trolling. Trolling is putting bait behind the boat. Bait normally used is squid that are lined up in several rows. Another bait technique is known as chumming or chunking. This technique requires fishermen to throw several pieces of bait fish overboard. Consistent throwing or presentation of bait fish usually attracts large game fishes.
