Brycon is a genus of fish in the family Bryconidae and order Characiformes found in freshwater habitats in Central and South America, ranging from southern Mexico to northern Argentina. [1] Despite not being closely related to true trout, they are sometimes called South American trout. [2] Members of the genus may be referred to by a number of other different common names in various languages. They reach a maximum length of 11.9–79.5 cm (4.7–31.3 in) depending on the species involved. [1] Some species perform seasonal breeding migrations. [3]

They feed heavily on fruits and seeds, but also take other plant material, invertebrates and small fish. [4] [5] Their food is typically taken from the water, but they are able to jump out of the water to "pluck" low-hanging seeds and fruits directly from trees. [2] Some seeds are crushed when eaten, but may also pass undamaged through the fish, making them seed dispersers. [2] [4] [5]

Brycon support important fisheries and based on a review by IBAMA, they are the fifth most caught fish by weight in the Brazilian Amazon. [3]

One fossil member of this genus is known in † Brycon avus (Woodward, 1898) from the Oligocene-aged Tremembé Formation of Brazil. [6] [7] A slightly older potential specimen of B. avus is also known from the Late Eocene/Early Oligocene of the Aiuruoca Basin. [8]
