2020 Sturgeon Moon

In ancient times, the changing seasons were often tracked by the lunar month (not the solar month).

Today, we have adopted many of these full Moon names as a nod to the change of seasons, too. Think of it as a way to stay connected with the natural world around us.

Specifically, Native American peoples often named the months after “start of season” cues. These names could vary by groups, depending on where the people lived. 

The Full Moon for August is called Sturgeon Moon because Native Americans knew that the giant sturgeon of the Great Lakes and Lake Champlain were most readily caught during this full Moon.

Other names for this Full Moon include ”Full Green Corn Moon,” signaling that the corn was nearly ready for harvest, “Wheat Cut Moon,” “Moon When All Things Ripen,” and ”Blueberry Moon.”

What a Sturgeon?

These prehistoric-looking fish have been traced back to around 136 million years ago and many people call them “living fossils.”

  • Females require around 20 years to start reproducing, and they can only reproduce every 4 years. However, they can live up to 150 years!
  • Today, there are about 29 species worldwide, including the lake sturgeon found in the Great Lakes. They have evolved in size from the size of a bass to monster sturgeon as big as a Volkswagen.
  • The lake sturgeon is quite rare today, due to intense overfishing in the 19th century, pollution, and damage to their habitat.


The word “sturgeon” means “the stirrer,” which is what this giant fish does when it is looking for food; it stirs up the mud and silt on river and lake bottoms. Notice the pointed snout and whisker-like tactile organs near the mouth. Credit: Tennessee Aquarium.
