August’s full moon is commonly referred to as the Sturgeon Moon because in the past, this was the time of year when sturgeon fish, especially in the Great Lakes and Lake Champlain, were most readily caught by Native American tribes. Sturgeon are large, prehistoric-looking fish that have been part of the North American ecosystem for millions of years and are known for their leaping abilities and for spawning in late summer.

During this month, these fish were abundant and easier to catch as they swam closer to the shores in preparation for spawning. Native American tribes relied heavily on sturgeon for food, and since the full moon marked important times in the fishing calendar, they named this particular full moon accordingly.

Different Native American tribes had their own names for the moons, and the name “Sturgeon Moon” was adopted by Algonquin tribes. Other names for the August full moon include the Green Corn Moon, Grain Moon, and Fruit Moon, reflecting the ripening crops and other seasonal changes that occur during this month.
