Ancient Maya built fish-trapping weirs in Belize

Discovery is first indication of aquaculture by ancient Maya

Live Science turned to a University of Cincinnati geography professor to understand the significance of the discovery of the first evidence of aquaculture among the ancient Maya. 

Researchers at the University of New Hampshire discovered evidence of ancient fish-trap weirs in Belize. The ancient Maya dug a network of canals to steer fish into the weirs, providing the first evidence of aquaculture.

Researchers said the fish traps could have fed thousands of people.

UC College of Arts and Sciences Professor Emeritus Nicholas Dunning was not part of the research project but has studied the ancient Maya in Mexico and Guatemala. He said the study provides some answers to fundamental questions about how the ancient Maya thrived 4,000 years ago.

“Over the past several decades, quite a few scholars of the ancient Maya, including myself, have suggested that aquaculture may have played an important role in the development of Maya civilization,” Dunning said. “However, the present study is the first that I know of to specifically attempt to test this hypothesis.”

Dunning called the study an important work in helping scholars of the ancient Maya understand the origins of sedentary society in the region.

An app that uses an AI model to read a single-lead ECG from a smartwatch can detect structural heart disease, researchers reported at the 2025 Scientific Sessions of the American Heart Association. Although the technology requires further validation, researchers said it could help improve the identification of patients with heart failure, valvular conditions and left ventricular hypertrophy before they become symptomatic, which could improve the prognosis for people with these conditions.
