I fished Pacu, also refereed to as “Morocoto” and also “Tambaqui”, on parts of the Amazon that flows through Venezuela, but only caught them up to 12 lb. They are interesting fish that are “omnivorous” eating like us, a mix of meat and vegetables. One of their favorite food is a lime-looking variety that grows on the threes that overhang the tributaries of the Amazon River. They ingest the fruit, but can’t digest the seeds, which they later deposit in different parts of the river and eventually some of those seeds take root and you have new trees growing producing more fruit.
Most “Tambaqui” between 35 and 40 kg were in fact hybrids from Brazilian fishing lakes. But in October 2013 the owner of Otorongo Expeditions caught a 37 kg specimen in the wild Amazon near the village of Oran, Peru and set a new rod & reel world record.
