During my 5 years of experience in the fishing field, I have often seen people get angry over the Swordfish vs Marlin debate. In my own fishing trips, the comparison between Swordfish and Marlin has also been a very exciting topic.
I have personally seen both Swordfish and Marlin in the ocean and gained experience in understanding them. In this article, I am going to explain the points about Swordfish vs Marlin that people often debate.
What is Marlin?
Marlin is a powerful, fast, and visually stunning fish that belongs to the Istiophoridae family. Its long spear-like bill and streamlined body give it the ability to reach very high speeds in the deep sea.
Marlin is known as the “King of the Ocean Speed” in the fishing world. Trolling techniques are mostly used to catch it, where the lure is dragged behind the boat.
Marlin is often found in warm oceans, such as the Atlantic, Pacific, and Indian Oceans.
Types of Marlin:
Blue Marlin, Black Marlin, and Striped Marlin are its popular types. According to my experience, when a Marlin is hooked, the reel literally starts snapping, with a very fast, powerful, and long jump.

What is Swordfish?
Swordfish is famous for its heavy sword-like bill. It is an aggressive predatory fish that belongs to the Xiphiidae family.
Swordfish prefer deep, cold water, so they are active at night.
Swordfish have a more muscular body. This fish is mostly caught by deep drop fishing, where heavy weights, deep rigs, and illuminated bait are used.
In my fishing trips, I have found the fight of a Swordfish to be more powerful and unpredictable than a Marlin.
Swordfish sometimes target straight deep water and show a lot of stamina.
