The Journey of the Silver King: Why Tarpon Migrate

For those who pursue saltwater angling, few fish inspire awe like the tarpon. Nicknamed the “Silver King” (as you will read, a more appropriate name might be “Silver Queen”), these prehistoric giants are known for introducing you to your backing in 0.6 seconds with blistering runs that often include explosive jumps with aerial acrobatics that looked practiced, and an almost mythical migration that brings them within reach of anglers every summer —  if you know where to be. But where do they come from, why do they migrate, and where are the hot spots during that time? Let’s learn a little more…

 

Where Do Tarpon Come From?

Doing a little research I learned that Tarpon (Megalops atlanticus) have been around for more than 100 million years, making them one of the oldest living fish species on Earth. They inhabit warm waters throughout the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico, as well as parts of the African coast. While baby tarpon thrive in mangrove lagoons and estuaries, adult tarpon are world travelers.

 

Why Do Tarpon Migrate?

Like many migratory fish, tarpon migrate for two main reasons: spawning and feeding. They are highly temperature-sensitive and thrive in waters between 74 – 88°F. When the conditions line up right, tarpon gather in small to massive schools to begin the migration along coastlines, following baitfish and preparing for offshore spawning events.

 

 

When Does the Migration Happen?

In the Western Atlantic and Caribbean, the prime window is May through August. This is when anglers will typically find schools of tarpon moving along the coastlines of Mexico, Belize, Cuba, and Florida. 

 

Migratory Tarpon vs. Baby Tarpon

I’ve been asked by clients on hosted trips, “If tarpon migrate a few months a year, why do we also find year-round tarpon, known as “juvenile” or “resident”, in these saltwater locations where the migration happens?” It comes down to habitat/protection and maturity. Juveniles will spend years in sheltered lagoons, mangroves, and backwaters where predators can’t reach them and food is abundant. Once they mature, they join the migrations offshore, where they’ll spawn and grow into giants. Tarpon generally begin migrating around 6-8 years of age, once they’re sexually mature and strong enough to handle long-distance travel and spawning cycles.

 

How Old and How Big Do They Get?

Tarpon are truly legendary fish:

• They can live for 50–60 years.
• They can grow to an impressive 8 feet in length and weigh 100-280 lbs.
• Females are typically larger than males hence the reference to “Silver Queen”, since they carry and release millions of eggs during each spawning event.

 

 

How Do They Travel?

Tarpon follow coastal highways and warm-water currents, often traveling in massive schools. That’s why anglers will see them in both Belize and Ascension Bay during the same months. These fisheries are part of the same migratory corridor, and during May – August, both regions are prime staging areas where tarpon pause to feed, rest, and prepare for spawning.
