Reproduction
Swordfish spawn in warm waters (warmer than 24 degrees C or 75 degrees F) during the warmer months of the year. Spawning can also happen year-round in some places, where the waters stay warm year-round. One of the best-known locations for the young to be born is in the Sargasso Sea.

Swordfish are at threat from commercial and sport fishing. They are harvested on a small and large scale around the world. In some places, swordfishing is illegal or at least regulated.

Wrap-Up
There is a surprising amount of risk factors when eating seafood. Many of these health risks are the result of bad farming practices and high levels of mercury. But as you have seen from our list, there are other detrimental factors to consider.

CRANIAL PENETRATION
The business end of any billfish is a weapon to be reckoned with. Some years ago, a mate off Louisiana ended up with a billfish’s bill in his head. Apparently it did no serious damage — go figure. And the same thing happened to an angler in a fighting chair off Panama.

What Is Mercury And Where Does It Come From?
Mercury is a heavy metal that is naturally formed in the Earth’s crust. While you may associate mercury with it’s silvery, liquid metallic state, mercury is mostly found as an inorganic salt or combined with other compounds.
Why Do Fish Contain Mercury?
As coal is combusted, small particles of mercury are blown into the air with other pollutants. When it rains, this atmospheric mercury is collected into water droplets and enters the ocean, where it is converted into methylmercury by waterborne bacteria and eventually makes its way into the bellies of fish!
Why Is Mercury Bad For Your Health?
In the perfect world, our beautiful bodies would be free from mercury. This toxic heavy metal serves no physiological purpose and only offers the potential to do harm. Yet the reality of living in our polluted modern environment means that all of us have at least trace amounts of mercury in our bodies.
The WORST fish for mercury levels
These fish are known to contain the highest levels of mercury and should be avoided (or at least minimized) for human consumption wherever possible.

How Much Fish Can I Safely Eat?
This is a hard question to answer for several reasons. Firstly, mercury levels in fish change significantly between country to country, and even among the various regions and waterways within countries. I strongly encourage you to check with your local fisheries and health advisories in addition to the information I outline here.
What About Supplements?
Fish oil supplements are generally considered to be low in mercury. Within America at least, a study of many common supplements revealed negligible levels of dioxins, PCBs or mercury. However, you may like to supplement with krill as an additional precaution.
Overview
Fisheries
Swordfish were harvested by a variety of methods at small scale (notably harpoon fishing) until the global expansion of long-line fishing. They have been fished widely since ancient times in places such as the Strait of Messina, where they are still fished with traditional wooden boats called feluccas and are part of the cuisine in that area.
Taxonomy and etymology
The swordfish is named after its long pointed, flat bill, which resembles a sword. The species name, Xiphias gladius, derives from Greek ξιφίας (xiphias, "swordfish"), itself from ξίφος (xiphos, "sword") and from Latin gladius ("sword"). This makes it superficially similar to other billfish such as marlin, but upon examination, their physiology is quite different and they are members of different families.
Description
They commonly reach 3 m (10 ft) in length, and the maximum reported is 4.55 m (14 ft 11 in) in length and 650 kg (1,430 lb) in weight. The International Game Fish Association's all-tackle angling record for a swordfish was a 536 kg (1,182 lb) specimen taken off Chile in 1953. Females are larger than males, and Pacific swordfish reach a greater size than northwest Atlantic and Mediterranean swordfish. They reach maturity at 4–5 years of age and the maximum age is belie…
Behavior and ecology
The popular belief of the "sword" being used as a spear is misleading. Their nose is more likely used to slash at its prey to injure the prey animal, to make for an easier catch. The use as an offensive spear in case of dangers against large sharks or animals is under review.
Mainly, the swordfish relies on its great speed and agility in the water to catch …
Recreational fishing
Recreational fishing has developed a subspecialty called swordfishing. Because of a ban on long-lining along many parts of seashore, swordfish populations are showing signs of recovery from the overfishing caused by long-lining along the coast.
Various ways are used to fish for swordfish, but the most common method is deep-drop fishing, since swordfish spend most daylight hours very deep, in the deep scattering layer. The boat is all…
