The ancient Maya civilization in Central America flourished due to an elaborate fish-trapping system that provided a vital source of food for the growing population. Researchers have discovered a network of earthen channels in present-day Belize that directed fish and other aquatic resources into ponds as flood waters receded. This system, dating back 4,000 years, could have fed around 15,000 people annually, according to a study published in Science Advances.
The construction of these channels indicates a shift towards aquatic foods as a dietary staple, particularly during times of drought when maize cultivation became less viable. The discovery also suggests that the rise of large Maya ceremonial and urban centers around 3,000 years ago may have been supported by the abundant aquatic resources provided by the fish traps.
Using advanced technology like drones and satellite imagery, researchers identified 167 channels covering nearly 42 square kilometers in the Crooked Tree Wildlife Sanctuary. Radiocarbon dating of excavated materials revealed that the fish-trapping system was initially built by hunter-gatherers around 4,000 years ago. These early inhabitants likely relied on a variety of aquatic foods such as fish, turtles, mollusks, and waterfowl for sustenance.
The Maya civilization, which thrived from 3,200 to 1,800 years ago, continued to utilize the fish-trapping system to access the rich aquatic bounty. One of the excavated channels even led directly to a major Maya center known as Chau Hiix. Future research will focus on uncovering remains of pre-Maya settlements near the fish traps and investigating similar canal networks in other wetlands in Belize and southern Mexico.
Overall, the discovery of this ancient fish-trapping system sheds light on the importance of aquatic resources in sustaining early civilizations in Central America. The intricate network of channels and ponds not only provided a reliable source of food but also played a crucial role in the development and expansion of the Maya civilization.
