Belem’s Ver-o-Peso open-air market, one of the largest in Latin America, was starting to get crowded with customers who came to buy from the colourful tropical fruits, herbs and vegetables on offer. Nearby, on the river, was the fish market, housed in a 19th-century iron building with high ceilings. Fishmongers had set up fish caught in the Amazon River and the Atlantic, which arrived at dawn. The salty odour of fish – new and old – hung in the humid air. Rows of stalls displayed their wares while sellers skilfully gutted fish as they waited for customers, setting the bones and heads to one side.
