Big-game fishing, open-water fishing, offshore boat fishing, and blue-water fishing are all terms used to describe deep sea fishing. It is a type of recreational fishing that takes place in waters deeper than 30 meters. Because of the requirement for the understanding of weather patterns, navigation, and safety guidelines, this sort of fishing is considered to be riskier and more involved than shallow water or lake fishing.
