Big game fishing is often referred to as offshore sportfishing, offshore gamefishing, and blue water fishing. It is a form of recreational fishing. They target large fish such as tuna and marlin.

The word "marlin" should be capitalized when it is used as part of a proper noun, such as a specific species name (e.g., Blue Marlin) or a title (e.g., Marlin Fishing Competition). Otherwise, it is typically lowercase.
